    Abstract
    A steel-concrete composite frame is typically used for building construction. Earthquake action and progressive collapse event caused by accidental local failures are the primary threats affecting the safety of steel-concrete composite frames. Currently, multi-hazard resistance and building resilience have garnered much research attention from the international civil engineering community. Based on the previously proposed first-generation seismic and progressive collapse resistant composite frame (SPCRCF), an improved second-generation seismic and progressive collapse resilient steel-concrete composite frame (SPCRCF-2) is ...

    A steel-concrete composite frame is typically used for building construction. Earthquake action and progressive collapse event caused by accidental local failures are the primary threats affecting the safety of steel-concrete composite frames. Currently, multi-hazard resistance and building resilience have garnered much research attention from the international civil engineering community. Based on the previously proposed first-generation seismic and progressive collapse resistant composite frame (SPCRCF), an improved second-generation seismic and progressive collapse resilient steel-concrete composite frame (SPCRCF-2) is proposed. The performance of SPCRCF-2 is compared with that of SPCRCF as well as a conventional steel-concrete composite frame (CSCCF) through seismic and progressive collapse experiments. Compared with CSCCF and SPCRCF, SPCRCF-2 is proven to be able to localize the damage to the replaceable energy-dissipating (ED) components under both seismic and progressive collapse conditions, whilst maintaining the other key components (beams and columns) damage-free. This special feature facilitates rapid repair of the structure thereby achieving multi-hazard resilience. Finally, theoretical models are proposed to calculate the initial stiffness and flexural yield strength of the beam-column joint connection in SPCRCF-2. The models are further validated by the experimental results.
