To identify the reasons for the deformation of the purlins and eliminate potential safety hazards, a comprehensive structural inspection was carried out on this factory building, the inspection results indicate that the sectional dimension deviations of the measured steel components and the strength of the steel are in line with the design and code requirements. However, the mid-span deflections of some purlin components fail to meet the code requirements. The bearing capacity of the suspended loads under different working conditions was analyzed: Among the 9 hanging load working conditions of the purlins, the bearing capacity of the purlins in 4 working conditions did not meet the code requirements;among the 2 hanging load working conditions of the main frame, the bearing capacity of the frame beam components in 1 working condition did not meet the code requirements, and the deflections of the frame beams in both 2 working conditions did not meet the code requirements.

Upon on-site examination, it was discovered that the connection (or node) construction mode of the building was correct. Only local surface flaws were present, and the operation was normal. The stress wave velocity of the randomly inspected wooden columns with surface cracking was close to the critical velocity, suggesting that no obvious cavities or decay defects existed within the measured wooden components. Based on the inspection outcomes, finite element computations were carried out for the wooden structure, arriving at the conclusion that the maximum stress value of the wooden members was smaller than the designed value of wood strength, and the vertical bearing capacity conformed to the requirements of the specifications.
