Abstract:Time-history analysis on nonlinear response of the out-of-code high-rise structure of No. 7 Building of CITIC City Plaza in Tianjin under rare earthquake was conducted according to the performance-based seismic analysis method. PERFORM-3D software was used to establish calculation model using the compound component consisted of moment plastic hinge, shear plastic hinge and elastic beam section to simulate the coupling beam, using the compound component consisted of fiber wall element, steel bar and shear material to simulate the shear wall, and using the linear beam element to simulate the floor beam. Mechanical performances of the out-of-code high-rise structure of No. 7 Building of CITIC City Plaza in Tianjin under rare earthquake were analyzed according to performance index system based on FEMA356 and ASCE41-06 criterions. Numerical calculation results indicate that the story drifts are in accordance with the regulation of the design code. Seismic performances of the structural coupling beams and shear walls conform to the pre-set seismic performance targets.
Keywords:out-of-code high-rise; seismic performance target; nonlinear response; performance evaluation; time-history analysis
