Performance-based engineering framework for assessing and enhancing seismic resilience of fire-exposed steel building structures

The reusability of steel structures after fire under seismic combinations of actions is particularly important within a variety of disciplines including ecology, sociology, and engineering.

The best solution is to assess the reparability and retrofit the fire-exposed steel structures for desired seismic performance on a scientific knowledge base.

The proposed PBE-FireSeismicRes project will develop a performance-based engineering framework for assessing and enhancing the seismic resilience of fire-exposed steel structure that is expected to raise major international scientific and industrial interest. This framework will be sophisticated and practical.

First, collaborative research efforts will be presented to develop high-fidelity computational models of fire-exposed steel structures to assess the seismic fragility of these structures with various fire and earthquake scenarios.

Second, seismic protective technologies will be developed to promote the application of the technologies and design to restore and upgrade the seismic resilience of deficient fire-exposed steel structures.

Following this, design criteria, design methodology, and risk-based assessment approach will be established within the performance-based engineering framework to promote the reusability of fire-exposed steel structures.

Together, the research outcomes from this project bear the potential to significantly advance the state of art in better safeguarding the built environment against earthquake hazards.
