Abstract
Hybrid reinforced concrete-steel (RCS) systems, which combine steel (S) beams and reinforced
concrete (RC) columns, offer more practical and cost-effective benefits than conventional steel and concrete moment frames due to their efficient use of materials.
Under the current International Building Code (IBC) and ASCE/SEI 7-05, RCS systems are classified as special moment frames and a response modification (R) factor of 8 is considered in their seismic design.
This research aims to evaluate the seismic resilience and R factor of RCS composite special moment frames following the methodology provided in FEMA P695. 3-bay multistory (3, 5, 10 and 15) archetypes were designed to conduct incremental dynamic analysis (IDA) in OpenSEES software. The nonlinear response of a typical RCS connection is implemented in the archetypes.
The fragility curves were obtained to investigate the safety margin against collapse outlined by FEMA P695. The results showed that the evaluated archetypes meet the FEMA P695 acceptance criteria for an R factor of 8.
