Seismic Damage Law of Steel Reinforced High Strength and High Performance Concrete Frame Columns
In this paper, the damage performance of 13 SRHSHPC frame columns are tested and analyzed under low cycle loading. The effect of concrete strength, axial compression ratio and shear span ratio on the damage of SRHSHPC frame columns is discussed, and then the experimental result is quantified with damage index. Based on existing seismic damage models, a new seismic damage model is put forward for SRHSHPC frame columns by a nonlinear combination of deformation and accumulative dissipation.
