Ensure a scientific examination and assessment of the damage to the steel structure post-fire. So, what inspections are required for the steel structure components post-fire?

1. Structural Steel Component Appearance Inspection

Inspect the appearance of the main steel structural components on-site, observing for any signs of coating peeling or deformation and bending.

2. Component Deformation Measurement

Steel column lateral movement is measured with a theodolite, and beam deflection is measured with a total station.

3. Component Mechanical Property Testing

Samples of damaged components from the fire scene were randomly selected and taken back to the lab for mechanical property testing to determine if they meet the mechanical property standards.

4. Structural Calculation and Component Verification

Based on on-site measurements and design drawings, considering dead loads, live loads, wind loads, snow loads, and seismic loads, the main structure model of the factory building was constructed and verified.

5. Authentication and Rating

Based on the post-fire structural steel inspection results, a mechanical analysis of the fire-resistant capacity of steel components was conducted, and a specific grading process was initiated for the post-fire steel components.

6. Provide key assessment conclusions, promptly formulate post-disaster response plans for damaged components, repair the main structures in the affected areas, and ensure fire prevention measures are in place during subsequent use.
