A Performance-Based Design Approach for Rectangular Concrete-Filled Steel Tube (RCFT) Frames under Seismic Loading
Performance of buildings under seismic loading is often decided based on damage states observed in the structural and non-structural members. The type and extent of damage states exhibit a wide range depending on the structural system resisting the earthquake loading. While developing performance-based design methodologies, it is critical to provide computational tools to assess the available capacity of structural members corresponding to various performance-levels (e.g., Immediate Occupancy, Life Safety). In this paper the progression of local damage states (e.g., concrete crushing, steel yielding) of rectangular concrete-filled steel tube (RCFT) members and the effect of local damage states on the structural performance of composite RCFT frames was investigated using a new distributed plasticity finite element formulation. The computational findings of the detailed structural performance, particularly the interaction of the local damage states, were compared with experiments, as well as to damage indices of RCFT members and frames proposed by. Adopting the local damage states as the main design parameters, a performance-based design methodology is introduced and illustrated for the RCFT beam-columns of a three-story composite RCFT frame.
