Abstract:The finite element method based on MIDAS finite element model to analyze and determinate the plastic hinge property of SRC members is adopted. Pushover analysis is performed on a hybrid frame of SRC column-steel beam with three bays and five stories based on different linear stiffness ratios of beam to column. The results demonstrate that hybrid frame of SRC column-steel beam which has reasonable linear stiffness ratio of beam to column has predominant earthquake-resistant behavior.
Keywords:SRC column-steel beam frame; Pushover analysis; linear stiffness ratio; plastic hinge; earthquake-resistant behavior
