The number of building components is numerous, and the parameters that need to be tested vary depending on the situation.
★ Count testing ★ The count testing items of the testing batch should be randomly sampled once or twice according to the quantity specified in Table 3.3.10 of the “Technical Standard for Building Structure Testing” GB50344-2019
.
Building structure detection refers to the detection work carried out to evaluate the quality of building structural engineering or identify the performance of existing building structures.
The corresponding situations for building structure testing vary greatly, and standardized testing items and quantities cannot be applicable to different situations.
02 Random Sampling Inspection Plan: Random sampling of inspection batches during building structure inspection can be divided into various forms such as counting inspection, metrological inspection, and material performance inspection.
Building structure testing should be based on the requirements of the client and the characteristics of the testing project, and the following methods should be used to determine the testing objects and quantity: (1) a comprehensive testing plan; (2) A plan for random sampling of testing batches; (3) Determine the plan for important testing batches; (4) Determine the plan for important testing items and objects in the testing batch; (5) Adopting a special structural testing technology plan in response to the client’s requirements.
Extracting appropriate testing batches to ensure sufficient representativeness is an important prerequisite for ensuring the accuracy and reliability of testing results.

A testing batch is a testing object composed of a certain number of components, with similar testing items, quality requirements, and production processes.
01 Full inspection plan: The following items should be checked and inspected using a full inspection plan: (1) component layout and important structural verification of the structural system; (2) Verification of support nodes and connection forms; (3) On site inspection of visible defects and damages in structural components, support nodes, and connections; (4) Inspection of obvious displacement, deformation, and deviation of structural components.
