EXPERIMENTAL STUDY ON SEISMIC DAMAGE OF SRHSHPC FRAMED STRUCTURE

Based on the test of a SRHSHPC framed structure under a low cycle reversed loading, the crack propagation and failure mode were observed in this test. According to the tested load-displacement hysteretic curve and skeleton curve of the frame, the relation between component damage and storey damage was analyzed. The storey damage model was established by introducing a joint location weighting coefficient; through analyzing the relation between storey damage and structure damage, the structure damage model of the SRHSHPC frame was established. The comparison of the calculated results with test results indicates that the proposed seismic damage model can appropriately describe the damage degree and evolution process of the SRHSHPC framed structure, and the migration evolution law between local component damage, local structure damage and global structure damage is revealed.
