Ensure scientific inspection and assessment of the damage to steel structures post-fire. So, what inspections are necessary for steel structure components post-fire?

1. Structural Steel Component Aesthetics 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 using a theodolite, and beam deflection is measured using a total station.

3. Component Mechanical Property Testing

Samples of components damaged in the fire were randomly selected on-site and brought back to the lab for mechanical property testing to determine if they meet the mechanical property standards.

4. Structural Calculations and Component Verification

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

5. Authentication & 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 main identification conclusions, promptly formulate post-disaster handling plans for damaged components, repair the main structures in the affected areas, and ensure fire prevention measures are in place during subsequent use.
