After-fire steel structure damage evaluation system based on mobile wireless technology

The invention relates to an after-fire steel structure damage evaluation system based on a mobile wireless technology. The system comprises an after-fire steel structure damage database, an after-fire steel structure residue carrying force calculating system, an after-fire steel structure safety performance authenticating system, an in-site data fast collecting system and a wireless communication transmission system, wherein the after-fire steel structure damage database, the after-fire steel structure residue carrying force calculating system and the after-fire steel structure safety performance authenticating system are built on the basis of a background server, the in-site data fast collecting system is built on the basis of mobile equipment, and the wireless communication transmission system realizes the wireless two-way connection of the in-site data fast collecting system and the background server. The after-fire steel structure damage evaluation system has the advantages that the in-site component data can be fast collected, in addition, each stage of indexes are subjected stage-by-stage recurrence calculation through the damage database, the residue carrying force calculation system and the safety performance authenticating system via quantitative analysis and qualitative analysis, the after-fire steel structure damage and the safety grade are automatically determined, and the after-fire steel structure damage and safety evaluation results are formed.
