【Abstract】 Structural dynamic elastic-plastic analysis was made for Wuhan Wanda super high-rise building,the constitutive relation of material was described by considering the seismic wave selection and seismic parameters etc.from the angle of performance-based design goal of the structure. ABAQUS was used for modeling and analysis,the bottom shear,interlayer displacement angle and the plastic damage of concrete were analyzed emphatically. In view of the elastic-plastic analysis conclusions,the measures which should be taken for seismic design of over-limit building were put forward.更多还原
