Technical Field
[0001] This invention belongs to the field of building construction technology, and specifically relates to a method for seismic reinforcement of old buildings. Background Technology
[0002] Old houses refer to buildings in cities or towns that have been in use for a long time and are severely worn, usually without modernization or renovation. While these houses may no longer meet the needs of residents, they still present many potential problems and challenges. In many cases, these old houses need to be demolished or renovated to make way for new buildings. In the process of urbanization and modernization, the current state and problems of old houses are becoming increasingly prominent. On the one hand, the demolition or renovation of old houses can free up land, providing space for the development of new buildings. On the other hand, old houses often have many potential problems and safety hazards.
[0003] Earthquakes are a common natural disaster that not only causes enormous losses to people but also tests the earthquake resistance of buildings. With the acceleration of urbanization, more and more buildings are being constructed, making earthquakes more frequent. Therefore, improving the earthquake resistance of older buildings has become particularly important. Earthquake-resistant technology refers to a series of technical measures to improve the earthquake resistance of buildings, including structural seismic design, the seismic performance of materials, and construction quality control. With the development of science and technology, earthquake-resistant technology is constantly advancing, and new seismic-resistant materials, design methods, and technologies are constantly emerging, which can improve the earthquake resistance of older buildings.
[0004] Seismic reinforcement of old buildings aims to improve their seismic performance and reduce the risk of collapse during earthquakes. However, existing seismic reinforcement structures for old buildings are complex and difficult to modify according to the actual structure of the old buildings, resulting in a waste of human and material resources. Summary of the Invention
[0005] In view of this, the present invention provides a method for seismic reinforcement of old buildings, which can solve the problem that the existing seismic reinforcement structure of old buildings is complex and difficult to modify according to the actual structure of the old building, resulting in a waste of human and material resources.
[0006] This invention is implemented as follows:
[0007] This invention provides a method for seismic reinforcement of old buildings, comprising the following steps:
[0008] S10: Conduct a comprehensive survey of the old building to determine its structural type, load-bearing capacity, and seismic resistance.
[0009] S20: Construction personnel establish a BIM model of the old building based on its actual condition, and determine the seismic reinforcement scheme of the old building based on the BIM model of the old building.
[0010] S30: Determine the reinforcement materials used in the seismic design based on the BIM model of the old building;
[0011] S40: Reinforce the old building using the reinforcement materials according to the seismic reinforcement plan for the old building;
[0012] S50: Determine the stability of the reinforced old building to ensure its seismic safety.
[0013] The technical effects of the seismic reinforcement method for old buildings provided by this invention are as follows: By conducting a comprehensive survey of the old building, the structural type, load-bearing capacity, and seismic resistance of the old building are determined. This allows for a comprehensive understanding of the overall structure of the old building, quickly identifying the parts with poor stability. This solves the problem that existing seismic reinforcement methods for old buildings are complex and difficult to modify based on the actual structure, resulting in a waste of manpower and resources. Furthermore, by having construction personnel create a BIM model of the old building based on its actual condition, the seismic reinforcement method can be determined based on the BIM model. The plan involves simulating the actual condition of the old building to determine the optimal seismic reinforcement scheme. Reinforcement and renovation are then carried out based on the building's specific conditions to improve construction efficiency and avoid wasting manpower and resources. The plan also involves using the BIM model of the old building to determine the necessary reinforcement materials for the seismic reinforcement scheme, ensuring all materials are prepared before construction to accelerate the process. Finally, the plan involves using the reinforcement materials to reinforce the old building according to the seismic reinforcement scheme, and determining the stability of the reinforced building to guarantee its seismic safety.
[0014] Based on the above technical solution, the seismic reinforcement method for old buildings of the present invention can be further improved as follows:
[0015] The specific steps involved in conducting a comprehensive survey of the old building to determine its structural type, load-bearing capacity, and seismic resistance include:
[0016] The first step is to classify the old houses according to their construction drawings and actual conditions, based on their category, purpose, and structural type.
[0017] The second step is for the construction personnel to establish a load-bearing capacity evaluation index system for the old building and determine its load-bearing capacity.
[0018] The third step involves comparing the earthquake acceleration that the old building can withstand with the target earthquake acceleration to determine the earthquake resistance of the old building.
[0019] The old buildings are categorized into single-story or multi-story residential buildings, multi-story office buildings, commercial buildings, and industrial buildings.
[0020] The old houses were classified as residential, office, and commercial.
[0021] The structural types of the old buildings are divided into single-story residential buildings, multi-story residential buildings, multi-story office buildings, commercial buildings, and industrial buildings.
[0022] Furthermore, based on the comparison between the seismic acceleration that the old building can withstand and the target seismic acceleration, the specific steps for construction personnel to determine the seismic resistance of the old building include:
[0023] The first step was for the construction workers to calculate the elastic seismic internal forces at different locations of the old building;
[0024] The second step involves the construction personnel calculating the strength and ductility of the reinforced concrete units at different locations of the old building based on the construction drawings and actual conditions, and assessing the ground motion acceleration borne by the reinforced concrete frame structure and the frame structure containing shear walls.
[0025] The third step involves the construction workers calculating the ground motion acceleration that different parts of the old building would experience when damaged, and then comparing it with the target earthquake acceleration to determine the seismic resistance of the different parts of the old building.
[0026] Furthermore, the specific steps for determining the earthquake resistance of the old building are as follows:
[0027] When different parts of the old building are damaged and the ground motion acceleration they experience is less than 10% of the target earthquake acceleration, the old building has low seismic resistance and needs to be reinforced.
[0028] Furthermore, the specific steps of the method for determining the target earthquake include:
[0029] The first step was for construction workers to collect historical earthquake magnitudes and the number of times they occurred in different regions.
[0030] The second step is for construction workers to collect the lengths of earthquake zones in different regions;
[0031] The third step involves the construction workers establishing a neural network model for determining the target earthquake of the old building. The model is trained using the length of the seismic zones in different regions as the data input and the historical earthquake magnitude and frequency in different regions as the output.
[0032] The fourth step involves the construction workers inputting the length of the seismic zone where the old house is located, as well as the magnitude and frequency of earthquakes over the years, into the neural network model for determining the target earthquake of the old house, and then optimizing the neural network model for determining the target earthquake of the old house.
[0033] The fifth step involves the construction workers inputting the length of the seismic zone below where the old house is located into the optimized neural network model for determining the target earthquake of the old house. This model predicts the frequency and magnitude of earthquakes in the area where the old house is located, ensuring that the earthquake with the highest predicted magnitude is the target earthquake.
[0034] Furthermore, the specific steps for the construction personnel to establish a load-bearing capacity evaluation index system for the old building and determine its load-bearing capacity include:
[0035] The first step is for the construction workers to determine the degree of thickness difference, the number of insufficient thicknesses, and the locations of insufficient thicknesses in different parts of the old building.
[0036] The second step involves the construction workers applying the above information to the load-bearing capacity assessment formula for the old building.
[0037] Where F = a * b * (1 - c)%;
[0038] D = 1 - (mn)%;
[0039] Where, a represents the initial bearing capacity at the corresponding location; b represents the degree of thickness difference at different locations of the old house; c represents the number of locations with insufficient thickness; F represents the bearing capacity at different locations of the old house; D represents the degree of thickness difference at different locations of the old house; m represents the original thickness at the corresponding location; n represents the actual thickness at the corresponding location.
[0040] The initial bearing capacity and the original thickness of the corresponding location of the old house were obtained from the construction drawings of the old house.
[0041] Furthermore, the specific steps for the construction personnel to establish a BIM model of the old building based on its actual condition include:
[0042] The first step involves the operators classifying the old house's design drawings, installation locations, support points, and support methods using a hierarchical classification method. They then propose an information organization-based coding rule to encode each part of the old house.
[0043] The second step involves the operators standardizing the parameters of each part of the old house and creating a shared parameter file for use in different families and projects.
[0044] The third step involves the operator inputting the shared parameter file into the Graphisoft Archicad software platform, constructing a 3D model of each part of the old house according to the design drawings, installation location, support points, and support methods of the old house, classifying and summarizing the 3D models, and establishing the old house family library.
[0045] The fourth step involves the operator calling upon various components in the old house family library based on the actual installation situation of the old house, and modifying the structural parameters of the old house through an external data file driver to generate corresponding instances.
[0046] The fifth step involves the operators performing standardized assembly to create a complete BIM model of the old building.
[0047] Furthermore, the specific steps for determining the seismic reinforcement scheme for the old building based on its BIM model include:
[0048] Structural panels are fixed at locations where the load-bearing capacity of the old building is 80-100%, and cracks are filled.
[0049] Concrete is poured at a location where the load-bearing capacity of the old building is 50-80%, and the thickness of the concrete is greater than 1 cm.
[0050] Steel columns are fixed at locations where the old building's load-bearing capacity is below 50% and its seismic resistance is low, to support the old building.
[0051] Furthermore, the specific steps for reinforcing the old building using the reinforcement material according to the seismic reinforcement scheme include:
[0052] The old building was reinforced according to its load-bearing capacity, from highest to lowest.
[0053] Furthermore, the specific steps for determining the stability of the reinforced old building and ensuring its seismic safety include:
[0054] The first step involves the construction team establishing a load-bearing capacity evaluation index system for the old building to determine the load-bearing capacity of the reinforced old building.
[0055] The second step involves comparing the earthquake acceleration that the old building can withstand with the target earthquake acceleration to determine the earthquake resistance of the old building after reinforcement.
[0056] The third step is to complete the reinforcement of the old house if the load-bearing capacity of different locations after reinforcement is greater than 90% and the seismic resistance is strong.
[0057] Compared with existing technologies, the beneficial effects of the seismic reinforcement method for old buildings provided by this invention are as follows: By conducting a comprehensive survey of the old building, the structural type, load-bearing capacity, and seismic resistance of the old building are determined, the overall structure of the old building is grasped, and the parts with poor stability are quickly identified. This solves the problem that existing seismic reinforcement methods for old buildings are complex and difficult to modify according to the actual structure of the old building, resulting in a waste of manpower and resources. Furthermore, by having construction personnel establish a BIM model of the old building based on its actual condition, the seismic resistance of the old building can be determined based on the BIM model. The seismic reinforcement scheme involves simulating the actual conditions of the old building to determine the optimal seismic reinforcement plan. Reinforcement and renovation are then carried out based on the actual conditions of the old building, improving construction efficiency and avoiding waste of manpower and resources. The reinforcement materials used in the seismic reinforcement scheme are determined based on the BIM model of the old building, and all materials are prepared before construction to accelerate efficiency. The old building is then reinforced using the reinforcement materials according to the seismic reinforcement scheme. Finally, the stability of the reinforced old building is determined to ensure its seismic safety. Attached Figure Description
