[Abstract]:The shaking table test of Y-HSS-EBF model specimen of 1: 2 scale three-story Y-shaped high strength steel composite eccentrically braced frame structure is carried out. The seismic behavior of the structure is investigated. Based on the restoring force model of the structure and the simplified model of the equivalent tensile rod, the plastic Kinematic connection element of multiple line segments in SAP2000 program is used to replace the tension bar. The simplified analysis of seismic response of Y-HSS-EBF structure is carried out, and the results of simplified analysis and test are given. The results of finite element analysis show that the structure has good seismic performance. The hysteretic curve of Y-HSS-EBF structure obtained by simplified calculation method is basically consistent with the experimental results, and the simplified analytical model can well simulate the nonlinear performance of the structure. The simplified calculation results of the shaking table model have certain accuracy. The simplified analysis model can be used for the elastic and elastoplastic seismic response analysis of Y-HSS-EBF structures. The simplified analysis model can be used to calculate the seismic action of the structure.
