Based on the test results and numerical analysis, rigidity degradation rules and hysteretic rules are analyzed. A trilinear hysteretic model considering rigidity degradation is proposed for steel reinforced high strength and high performance concrete frame joints. The proposed restoring force model tallies with the test curves, which can be a good reference for seismic design of SRC structures.
