Once the upper structure work is completed, the stability of the foundation becomes the issue. Generally, a high-precision total station is used to measure and judge the deflection of the column frames and the corners of the building; if necessary, settlement observation of the building is conducted to determine the stability of the foundation.
Detailed Knowledge of Steel Structure Testing Mechanics: How much do you know about steel structure testing - steel structure mechanics: a. Testing of metal materials such as steel plates and round steel for tensile strength, yield strength, elongation after break, bending tests, impact tests (room temperature impact, low temperature impact,时效impact), hardness, and toughness and plasticity; tensile testing of rebars (yield strength, tensile strength), bending, etc. Z-direction tensile test of steel plates. b. Welding process evaluation of metal welded parts, tensile and bending tests of rebars. c. Metal hardness test is the ability of metal to resist local deformation, which is plastic deformation, indentation, or scratch, and is a measure of the degree of softness or hardness of metal materials. Hardness includes: Vickers hardness, Leeb hardness, Rockwell hardness, Brinell hardness.

Structural steel inspection is a specialized aspect of engineering structure inspection. It is not necessarily required to provide a separate inspection report for the entire building or structure's reliability. The results of the structural steel inspection can be listed as a single item in the overall inspection report. When a separate structural steel专项 report is requested, the inspection findings and rating results should be listed, along with recommendations and suggestions for handling, including usage management, maintenance, reinforcement, modification, or demolition, as required. Additionally, suggestions for seismic resistance and disaster mitigation strategies should also be provided.

During the operation of buildings, not only do they require regular management, but timely repairs are also necessary to fulfill the functions assigned by their design. At the same time, there are still a few buildings that may need reinforcement due to improper design, construction, or use, or may require renovation due to changes in use, or may need to be addressed due to changes in environmental conditions, etc. To handle these situations, the necessity of steel structure inspections is crucial. How much do you know about steel structure inspections? Steel structure inspections involve on-site surveys and testing of the structure, considering the impact of any defects, and assessing the reliability of the building structure according to the requirements of relevant codes or standards. To effectively address these issues, it is essential to have a clear understanding of the problems related to the building's safety, usability, and durability, in order to develop safe, reasonable, economic, and feasible solutions. What the reliability of the building provides is the correct evaluation of these problems.

All these factors necessitate reinforcement of the building structure. To economically, reasonably, and effectively reinforce the structure, it is crucial to understand the mechanism of its damage and conduct quality inspections on the building structure. This type of quality inspection of the building structure is different from construction quality inspection, as it involves direct sampling or direct testing on the existing building.
General procedures for safety inspections of industrial steel structure factory buildings:
1. On-site survey
2. Develop a testing plan (based on national building inspection standards, such as: "Code for Load of Building Structures," "Code for Design of Steel Structures," etc.).
3. Factory building, structural layout, and component dimensions verification
4. Relative settlement detection at the base of the factory building columns and column tilt detection.
5. Conduct a factory condition inspection.
6. Factory Structure Load-Bearing Capacity Calculation and Analysis
7. Analysis of Factory Construction Measures
8. Provide a factory safety inspection report.
