Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, and more specifically, relates to a construction method for buckling-restrained bracing members. Background Technology

[0002] In recent years, with the rapid development of bridge engineering, traditional support structures can no longer meet the needs of large-scale bridge construction. Therefore, curved surface restrained support components have become an effective technical solution. However, some technical problems still exist in the construction process of curved restrained support components. This invention aims to solve these problems and proposes a new construction method. my country's bridge engineering construction has developed rapidly, with many long-span and ultra-high bridges being completed and opened to traffic. This has placed higher demands on bridge construction. Traditional simply supported beam erection systems are no longer sufficient to meet the needs of large-scale bridge construction. As a new type of support system, the buckling restrained support system has excellent overall stiffness and structural rationality, and can effectively solve the construction problems of long-span bridges. The buckling restrained support system consists of curved restrained components with closed-loop cross-sections. The components are connected by nodes, and a precise control and adjustment system is set at the nodes to achieve accurate positioning and force transmission. This system has high stiffness and good wind resistance stability, making it an ideal solution for large-scale bridge construction.

[0003] However, this system also has some problems:

[0004] (1) The components are numerous and the stress is complex, requiring high construction technology;

[0005] (2) The node connection and control system have high accuracy requirements and are difficult to install and debug;

[0006] (3) Curved components have complex stress and deformation patterns, and improper handling can easily cause damage.

[0007] (4) The entire system has high stiffness and high requirements for foundation and anchorage.

[0008] Currently, this system is not yet mature enough in construction applications, lacking a complete and systematic construction plan and technical specifications. Improper construction methods may lead to safety accidents such as insufficient load-bearing capacity and overall instability. In particular, existing technologies often rely on manual experience to determine the construction sequence, resulting in a lack of mechanical calculations and insufficient safety during construction. Summary of the Invention

[0009] In view of this, the present invention provides a construction method for buckling restraint bracing members, which can solve the technical problem in the prior art that the judgment of the construction sequence is often based on human experience, and the resulting construction sequence often lacks mechanical calculations, leading to insufficient safety in the construction process.

[0010] This invention is implemented as follows:

[0011] This invention provides a construction method for a buckling-restrained brace, comprising the following steps:

[0020] Based on the above technical solution, the construction method of the buckling restraint brace of the present invention can be further improved as follows:

[0021] The steps of formulating a construction plan and determining the construction area and sequence specifically include: collecting engineering design data and related drawings to fully understand the project content, including the structural form, dimensional parameters, materials and performance, load conditions, and calculation results of the structures; accurately dividing the construction area based on the engineering design drawings and clarifying the detailed installation positions of the buckling-restrained braces; rationally planning construction transportation and temporary facilities based on full consideration of the specific site conditions; and determining a reasonable construction sequence and formulating a detailed construction plan based on the stress characteristics and calculated internal forces of each component using scientific methods.

[0022] The method for determining the construction sequence is to use topological sorting to sort the components according to their stress dependencies to obtain the installation sequence.

[0023] The steps for preparing buckling-restrained bracing components and necessary construction equipment according to the construction plan specifically include: clarifying the specific specifications and required quantities of various buckling-restrained bracing components according to the determined construction plan and sequence requirements; organizing the material supply department to purchase the determined components from qualified suppliers; formulating a scientific material transportation and on-site storage plan, and taking protective measures such as rainproofing, moisture-proofing, and rust prevention; strictly inspecting the quality of the components, paying particular attention to the control of prestressing stress in prestressed components; and determining the required construction equipment such as lifting machinery, positioning and adjustment equipment, and temporary support systems according to the specific construction conditions and plan requirements.

[0024] The steps of installing buckling-restrained braces (BRBs) within the construction area according to the construction sequence specifically include: hoisting the BRBs into position using lifting machinery according to the predetermined construction sequence; accurately determining the spatial position of the BRBs using precision measuring and positioning equipment; precisely adjusting the position of the BRBs using various mechanical devices to ensure correct alignment with adjacent BRBs; firmly connecting the BRBs using welding, bolting, or other methods; setting up temporary supports as required to ensure the positioning stability of the BRBs; and sequentially installing all BRBs in this stage.

[0025] The steps of using construction equipment to position and fix the buckling-restrained brace include: selecting a reasonable connection and fixing method, such as welding, high-strength bolt fixing, or embedded fixing, based on the specific stress calculation results of the component; developing precise and controllable construction plans and quality standards for each fixing method; setting accurate control benchmarks and elevations for later use; taking reinforcement measures to ensure reliable connections; and conducting quality inspections after completion and promptly repairing defects.

[0026] The measurement and inspection steps specifically include: using precision measuring equipment to check whether the component position conforms to the design; using equipment such as a level to detect the horizontality and verticality of the component; using methods such as probing and impact to check the connection firmness; using methods such as weld inspection to check the connection quality; checking the tightening torque of bolted connections; using methods such as load testing when necessary to test the stiffness and load-bearing capacity of the component; if the test or inspection results are unqualified, rework or reinforcement is carried out; and completing the quality inspection records for review.

[0027] The steps for protecting buckling-restrained braces specifically include: marking the components and parts requiring protection before construction begins; selecting appropriate protective materials according to protection requirements; taking effective measures such as wrapping and covering to reduce mechanical impact on components; setting up shading facilities to prevent overheating or wind and rain erosion; and regularly inspecting the protection status and promptly repairing any problems.

[0028] The steps for monitoring and adjusting the installation of buckling-restrained braces during construction include: setting up automated monitoring equipment to monitor the stress and deformation of the components in real time; setting reasonable alarm values ​​and promptly alarming when abnormalities occur; periodically re-measuring to determine whether adjustments are needed; and taking timely adjustment measures such as tightening bolts and welding reinforcement based on the monitoring results until the results meet the requirements.

[0029] Furthermore, the topological sorting steps specifically include:

[0030] Build the graph, treat each component as a node, and the force dependence relationship as a directed edge;

[0031] Calculate the in-degree of each node;

[0032] Initialize the set S of nodes with an in-degree of 0;

[0033] Repeat the process of deleting nodes from S and updating the graph;

[0034] The order in which records are deleted is used as the result of topological sorting.

[0035] Compared with existing technologies, the beneficial effects of the construction method for buckling-restrained braced members provided by this invention are as follows: A topological sorting algorithm is used to rationally determine the installation sequence of the components. This algorithm fully considers the force dependencies between components, can rationally arrange the order of installation, effectively ensures the structural bearing capacity, avoids structural safety accidents caused by unreasonable sequences, and improves the rationality of construction. A detailed positioning and adjustment plan is formulated, and precise measuring equipment is used to ensure that the spatial position and geometry of curved components fully meet the design requirements, ensuring the accuracy of node connections and improving the overall stiffness of the structure. This solves the technical problem in existing technologies where the judgment of the construction sequence often relies on manual experience, resulting in a lack of mechanical calculations and insufficient safety during construction.

[0052] The specific implementation methods of the above steps are described in detail below:

[0053] Detailed implementation of step S10:

[0054] 1. Collect engineering design data and drawings, and understand the project content in detail, including but not limited to the structural form and dimensions of bridges or other structures, the materials used and their performance parameters, load conditions and calculation results, etc.

[0055] 2. Based on the engineering design drawings, divide the construction area and determine the installation locations of the buckling-restrained braces.

Use finite element analysis or other calculation methods to determine the internal force distribution and key components of each member.

[0057] 4. Based on the stress analysis results, the topological sorting algorithm is used to determine the installation sequence of the buckling-restrained brace members:

[0058] (1) Based on the force relationship between components, establish the topology of the construction sequence. Each node represents a component, and the directed edge represents the force dependency relationship.

[0059] (2) All nodes with an in-degree of 0 represent the components that can be installed first. Output these nodes.

[0060] (3) Delete these component nodes and related edges, and repeat step (2) until all nodes are deleted.

[0061] (4) Record and output the topology sorting result, which is the construction sequence.

[0062] 5. Considering the availability of construction machinery and manpower, as well as the conditions of the work surface, rationally arrange the construction operation surface and hoisting positions, and formulate a specific construction plan. Special emphasis should be placed on ensuring the continuity of the load-bearing chain.

[0063] 6. The buckling-restrained bracing members constituting the support system shall have their cross-sectional dimensions, materials, and prestress parameters determined based on the calculated internal forces.

[0072] 1) Construct a directed graph G = (V, E), where:

[0073] V = {v1, v2, ..., v} n} represents n buckling-restrained braces.

[0074] E = {(v i ,v j )|v i ,v j ∈V} represents the force dependency relationship between components, where v i Requires v j Previous installation

[0075] 2) Calculate v for each node i in-degree:

[0076] inDegree(vi )=|{(v j ,v i )∈E}|, that is, with v i Number of nodes with dependencies

[0077] 3) Initialize the set of zero-in-degree nodes:

[0078] S={v i |inDegree(v i )=0}

[0079] 4) While S is not empty, perform the following loop:

[0080] Take a node v from S. i

[0081] Output v i

[0082] Delete v from graph G i

[0083] forall v j Satisfy (v) i ,v j )∈E:

[0084] inDegree(v j =inDegree(v j )-1

[0085] If inDegree(v j If ) = 0, add v to S j

[0086] 5) Output the topology sorting result

[0087] The variables and constants are defined as follows:

[0088] v i (i = 1, 2, ..., n): represents the i-th buckling-restrained support member.

[0089] V: Represents the set of all buckling-restrained braced members.

[0090] E: Represents the set of force dependencies between components.

[0091] inDegree(v i ): represents point v i in-degree, i.e., dependency on v i Number of nodes

[0092] S: The set of nodes with an in-degree of 0, which can be installed first.

[0093] Algorithm idea:

[0094] Using topological sorting, the installation order is obtained by sorting the components according to their force dependencies. Specifically, it includes:

[0095] 1) Graphing: Treat each component as a node and the force dependency relationship as a directed edge.

[0096] 2) Calculate the in-degree: Calculate the in-degree of each node.

[0097] 3) Initialize the set S of nodes with an in-degree of 0.

[0098] 4) Repeatedly delete nodes in S and update the graph.
