Technical Field

[0001] This application relates to the fields of construction technology and software technology, and in particular to a method and apparatus for evaluating prefabricated structures based on toughness values ​​and carbon emissions. Background Technology

[0002] Against the backdrop of my country's comprehensive green transformation of economic and social development and large-scale development of underground space, prefabricated structures, with their advantages in construction efficiency, have been widely used in projects such as underground railway stations. In the future, with the increase in urban population density, the stock of prefabricated structures will continue to grow.

[0003] Furthermore, prefabricated structures are highly susceptible to damage under seismic forces, uneven foundation settlement, or long-term water erosion. Damage to prefabricated structures necessitates repair, a significant challenge in urban emergency disaster management that often requires extraordinary resource inputs, leading to a surge in greenhouse gas emissions and a substantial increase in environmental burden.

[0004] However, existing prefabricated structure evaluation methods are limited to the early design stage of prefabricated structures, while repair solutions for prefabricated structures occur in the later repair stage after the prefabricated structure has been damaged. Due to the significant differences between the early design stage and the later repair stage, existing prefabricated structure evaluation methods cannot determine the evaluation value of the repair solution. Therefore, how to determine the evaluation value of the repair solution is a technical problem that urgently needs to be solved. Summary of the Invention

[0110] The failure volume of each interface is summed to obtain the failure amount of the prefabricated structure.

[0111] Among them, the damage amount of prefabricated structures is the core indicator of the cumulative damage and failure degree of prefabricated structures under load. By monitoring the damage amount of prefabricated structures, weak parts of prefabricated structures can be accurately identified, providing data support for maintenance and reinforcement, and avoiding sudden collapse accidents.

[0112] S204, When the damage to the prefabricated structure is within the damage range, obtain the repair plan for the prefabricated structure, and generate the carbon emission of the repair plan through the carbon emission model;

[0113] Wherein, when the damage to the prefabricated structure is within the damage range, a repair plan for the prefabricated structure is obtained, and the carbon emission of the repair plan is generated through a carbon emission model, including:

[0119] When the damage to the prefabricated structure is within the range of minor damage, a repair plan for the prefabricated structure is obtained from the database corresponding to the range of minor damage.

[0120] When the damage to the prefabricated structure is within the moderate damage range, a repair plan for the prefabricated structure is obtained from the database corresponding to the moderate damage range.

[0121] When the damage to the prefabricated structure is in the high-damage range, a repair plan for the prefabricated structure is obtained from the database corresponding to the medium-damage range.

Based on the length of each interface, the moment of inertia of the complete part of each interface, the movement distance of the neutral axis of each interface, and the contact surface stiffness model, the contact surface stiffness of the prefabricated structure is generated. The start and end times are obtained from the repair plan. Based on the contact surface stiffness of the prefabricated structure, the material elastic modulus of the prefabricated structure, the start and end times, and the toughness model, the toughness value of the prefabricated structure is generated. Through the evaluation model, the carbon emissions of the repair plan are calculated as a ratio to the toughness value of the prefabricated structure to generate the evaluation value of the repair plan.

[0128] Among them, the contact surface stiffness model is a calculation model for the contact surface stiffness of prefabricated structures.

[0129] Among them, the toughness value model is a calculation model for the toughness value of prefabricated structures.

[0132] ;

[0133] ;

[0134]

[0135] Length of the interface;

[0136] It is the first The length of the Eth unit of the complete portion of the interface;

[0137] It is the first The moment of inertia of the complete portion of the interface;

[0138] It is the first The material elastic modulus of the Eth element of the complete portion of the interface;

[0139] di is the first The distance the interface moves along its neutral axis;

[0140] It is the first The number of units in a complete part of an interface;

[0141] ;

[0142] This refers to the total number of interfaces;

[0143] .

[0144] Among them, the contact surface stiffness of a prefabricated structure refers to a key parameter indicating the resistance of the connection interface to deformation under stress. The greater the contact surface stiffness of a prefabricated structure, the stronger its ability to resist relative deformation under stress. Conversely, the smaller the contact surface stiffness, the weaker its ability to resist relative deformation under stress.

[0145] Among them, the The overall part of the interface includes the first The complete and damaged parts of the interface.

[0146] The toughness value model is defined as follows:

[0147] ;

[0148] ;

[0149] ;

[0150] ;

[0151] in, It is the first The length of each interface;

[0152] For the first The distance from the neutral axis of each interface to its top edge;

[0153] For the first The moment of inertia of the entire interface;

[0154] b is the thickness of the wall; t is the initial time; t is the final time.

[0155] The relative stiffness of the prefabricated structure at the termination moment;

[0156] Let be the elastic modulus of the prefabricated structure at time t;

[0157] Let be the moment of inertia of the prefabricated structure at time t;

[0158] The elastic modulus of the material in the prefabricated structure;

[0159] for Toughness value;

[0160] To represent the relative stiffness of the prefabricated structure at the initial moment;

[0161] express In the interval [ The cumulative value on [T].

[0162] The evaluation model is defined as follows:

[0163]

[0164] This indicates the evaluation value of the repair plan. This indicates the toughness value of the prefabricated structure. This indicates the carbon emissions of the remediation plan.

[0165] For ease of explanation, please refer to Figure 6 , Figure 6These are sample diagrams of the assembled structure provided in the embodiments of this application;

[0166] Figure 6 Precast component 1 and precast component 2 are shown. The prefabricated structure is composed of precast component 1 and precast component 2. Precast component 1 and precast component 2 have contact parts, which include T1, T2, T3 and T4. T1 represents the first interface, T2 represents the second interface, T3 represents the third interface and T4 represents the fourth interface, and b is the thickness of the wall.

[0167] Furthermore, for the sake of clarity in explaining the first interface, please refer to... Figure 7 , Figure 7 This is an example diagram of the interface provided in the embodiments of this application.

[0168] Figure 7 T1, T2, T3, and T4 are shown; T1 represents the first interface, T2 represents the second interface, T3 represents the third interface, T4 represents the fourth interface, and b is the thickness of the wall.

[0169] Before the destruction, the first interface was a whole; the first interface did not have any destroyed or intact parts. Length of the interface; For the first The distance from the neutral axis of each interface to its top edge.

[0170] After being destroyed, the first interface is no longer a single entity; it consists of both destroyed and intact parts. The length of the destruction of the first interface is the length of the destroyed part of the first interface.

[0171] in, By obtaining the length of the complete portion of the first interface, the length of the second interface can be determined. The number of units in the complete part of each interface is used to calculate the stiffness of the complete part of the first interface. Since the processing procedures for the second, third, and fourth interfaces are the same as those for the first interface, the processing procedures for the second, third, and fourth interfaces will not be described in detail here.

[0172] refer to Figure 8 , Figure 8 This is an example diagram of the structural corner provided in the embodiments of this application.

[0173] Figure 8 Precast component 1 and precast component 2 are shown. Precast component 1 and precast component 2 in the prefabricated structure are prone to bending failure under external loads. The structural rotation angle can be obtained by measurement.

[0174] Among them, the smaller the evaluation value of the repair scheme, the less carbon emissions the repair scheme releases and the better the overall performance, while achieving the same toughness value of the prefabricated structure.

[0175] From a resilience perspective, achieving the same resilience value as a prefabricated structure through a remediation plan means that the plan meets the resilience standards for prefabricated structures. From an environmental perspective, the lower the carbon emissions released by the remediation plan, the less energy resources it consumes during implementation, and the lighter the additional burden on environmental elements such as the atmosphere and soil. This effectively reduces the risk of secondary ecological damage that may be caused by the remediation activities themselves, indicating that the remediation plan can reduce carbon emissions while ensuring safety. Therefore, the lower the assessment value of the remediation plan, the better its overall performance in terms of both resilience and environment.

[0176] The higher the evaluation value of the repair scheme, the more carbon emissions it releases and the worse its overall performance, while achieving the same toughness value of the prefabricated structure.

[0177] From a resilience perspective, if a remediation plan achieves the same resilience value as a prefabricated structure, it means the plan meets the resilience standards for prefabricated structures. From an environmental perspective, the higher the carbon emissions released by the remediation plan, the greater the energy and resource consumption during implementation, and the heavier the additional burden on environmental elements such as the atmosphere and soil. This effectively increases the risk of secondary ecological damage that may be caused by the remediation activities themselves, indicating that the remediation plan cannot reduce carbon emissions while ensuring safety. Therefore, a higher assessment value for a remediation plan means a worse overall performance in terms of both resilience and environmental impact.

[0178] The prefabricated structure evaluation method includes the following steps: First, based on the length of each interface, the moment of inertia of the complete portion of each interface, the distance the neutral axis of each interface has moved, and the contact surface stiffness model, the contact surface stiffness of the prefabricated structure is generated. Then, the start and end times are obtained from the repair plan. Finally, based on the contact surface stiffness of the prefabricated structure, the material elastic modulus of the prefabricated structure, the start and end times, and the toughness model, the toughness value of the prefabricated structure is generated. Then, through the evaluation model, the ratio of the carbon emissions of the repair plan to the toughness value of the prefabricated structure is calculated to generate the evaluation value of the repair plan.

[0179] Obtain the evaluation values ​​of different repair schemes, sort the evaluation values ​​of different repair schemes, and select the repair scheme with the smallest evaluation value as the optimal repair scheme.

[0180] For ease of explanation, the following example is provided:

[0181] For example, there are repair scheme 1, repair scheme 2, and repair scheme 3; the evaluation value of repair scheme 1 is evaluation value 1, the evaluation value of repair scheme 2 is evaluation value 2, and the evaluation value of repair scheme 3 is evaluation value 3. Sort the evaluation values ​​1, 2, and 3.

[0182] If the evaluation value 1 is the smallest, then repair scheme 1 is selected as the optimal repair scheme.

[0183] If the evaluation value 2 is the smallest, then repair scheme 2 is selected as the optimal repair scheme.

[0184] If the evaluation value 3 is the smallest, then repair scheme 3 is selected as the optimal repair scheme.

[0185] The beneficial effects of this application's embodiments are twofold. Firstly, based on the length of each interface, the moment of inertia of the complete portion of each interface, the movement distance of the neutral axis of each interface, and the contact surface stiffness model, the contact surface stiffness of the prefabricated structure is generated. The start and end times are obtained from the repair scheme. Based on the contact surface stiffness of the prefabricated structure, the material elastic modulus of the prefabricated structure, the start and end times, and the toughness model, the toughness value of the prefabricated structure is generated. Through the evaluation model, the carbon emissions of the repair scheme are calculated as a ratio to the toughness value of the prefabricated structure, generating an evaluation value for the repair scheme, thus solving the problem of how to determine the evaluation value of the repair scheme. Secondly, the smaller the evaluation value of the repair scheme, the less carbon emissions are released under the premise of achieving the same toughness value of the prefabricated structure, and the better the overall performance. Conversely, the larger the evaluation value of the repair scheme, the more carbon emissions are released under the premise of achieving the same toughness value of the prefabricated structure, and the worse the overall performance of the repair scheme.

[0190] In this embodiment of the application, the carbon emissions of the repair scheme are calculated as a ratio to the toughness value of the prefabricated structure by using an evaluation model to generate an evaluation value for the repair scheme.

Figure 4 The prefabricated structure evaluation device 400 shown can be applied to, for example... Figure 1 The application scenario diagram shows electronic devices. The following section uses electronic devices as an example to illustrate this. Figure 4 The prefabricated structure evaluation device 400 shown will be described in detail. The prefabricated structure evaluation device 400 may include an acquisition module 401, a generation module 402, an addition module 403, a selection module 404, and an evaluation module 405.

[0192] The acquisition module 401 is used to acquire monitoring data of the prefabricated structure and obtain the damage length of each interface of the prefabricated structure from the monitoring data.

[0193] The generation module 402 is used to generate the failure volume of each interface based on the failure length, structural rotation angle and volume model of each interface. The structural rotation angle is the rotation angle formed by splicing different prefabricated components in the prefabricated structure.

[0194] The summation module 403 is used to sum the failure volumes of each interface to obtain the failure amount of the prefabricated structure.

[0195] Module 404 is selected to obtain a repair plan for the prefabricated structure when the damage to the prefabricated structure is within the damage range, and to generate the carbon emission of the repair plan through a carbon emission model.

It obtains the start and end times from the repair plan, and generates the toughness value of the prefabricated structure based on the contact surface stiffness, the material elastic modulus of the prefabricated structure, the start and end times, and the toughness model. Through the evaluation model, it calculates the ratio between the carbon emissions of the repair plan and the toughness value of the prefabricated structure to generate the evaluation value of the repair plan.

[0198] The beneficial effects of this application's embodiments are twofold. Firstly, based on the length of each interface, the moment of inertia of the complete portion of each interface, the movement distance of the neutral axis of each interface, and the contact surface stiffness model, the contact surface stiffness of the prefabricated structure is generated. The start and end times are obtained from the repair scheme. Based on the contact surface stiffness of the prefabricated structure, the material elastic modulus of the prefabricated structure, the start and end times, and the toughness model, the toughness value of the prefabricated structure is generated. Through the evaluation model, the carbon emissions of the repair scheme are calculated as a ratio to the toughness value of the prefabricated structure, generating an evaluation value for the repair scheme, thus solving the problem of how to determine the evaluation value of the repair scheme. Secondly, the smaller the evaluation value of the repair scheme, the less carbon emissions are released under the premise of achieving the same toughness value of the prefabricated structure, and the better the overall performance. Conversely, the larger the evaluation value of the repair scheme, the more carbon emissions are released under the premise of achieving the same toughness value of the prefabricated structure, and the worse the overall performance of the repair scheme.
