Abstract:Taking a frame-shear wall structure in a high seismic intensity region as an example, the specific seismic performance targets of the structure were determined according to the height and the complexity. The right value of the ground motion parameter in the fortification seismic analysis was discussed. The elastic analysis under frequent earthquake, non-yielding analysis under fortification earthquake and elastic analysis under fortification earthquake on the vertical components were conducted, and internal force results were compared. The minimum shear weight ratio and the tensile stress limit of vertical members under horizontal force were discussed and determined. The stress conditions of the shear wall, frame column, coupling beam and frame beam components under fortification earthquake were clarified using a quantitative way. The results show that the structure can meet the predetermined seismic performance targets.
Keywords:out-of-code frame-shear wall structure; performance design under fortification earthquake; performance status
