In the process of using the house, the use function may be changed, such as changing the factory into an office building, office building into a shopping mall, etc. It may also be necessary to carry out local structural changes such as local opening of doorways, local opening of floor slabs, and local extracting of beams and pulling out of columns, etc. All these factors have an impact on the structural safety of the house. These factors have an impact on the structural safety, and it is necessary to carry out housing safety inspection and assessment, check the structural components and assess the structural safety in accordance with the new use function and structural arrangement. When the function and structural changes are large, the seismic performance needs to be evaluated. Therefore, the testing of the change in the use of housing functions is mainly to test the safety and seismic performance of the housing under the situation of changing the functional loads.

Once a house changes its use or structure, such as removing load-bearing walls for renovation or remodeling a factory building, it is necessary to conduct a safety inspection of the remodeled house. Before the house is remodeled, added floors, structural changes or change of use of the house, increase the use of load, through the structure of the house test, the feasibility of the change of the structure and use of the house to make an evaluation of the structure and function of the house, that is, the structure of the house and the use of the function of the change of the test.

I. Practicality of the inspection of change of use function of the house

1、The basis for the change of the function of the house.

2. The basis for the safety after the change of the function of housing use.

3、Provide reference for subsequent construction.

Change of Use Inspection

Once a house changes its use or structure, such as removing load-bearing walls for renovation or remodeling a factory building, it is necessary to conduct a safety inspection of the remodeled house. Before the house is remodeled, added floors, structural changes or change of use of the house, increase the use of load, through the structure of the house is tested, the feasibility of the change of the structure and use of the house is evaluated, i.e., the structure of the house and the use of the change of the function of the test.

I. Practicality of the inspection of change of use function of the house

1、The basis for the change of the function of the house.

2. The basis for the safety after the change of the function of housing use.

3, for subsequent construction to provide reference.

Use function change detection

Second, the actual test content

1, the client to provide housing use change program, the inspector according to the program design analysis.

2、Material performance testing of house structural components.

3, the bearing capacity of the house and the main structural components according to the relevant regulations and standards for calculation.

4, according to the use of the house function change to observe the overall force of the house whether the change in seismic identification of the house.

5、According to the above information and data, evaluate the feasibility of the follow-up of the project of changing the use function of the house.
