Abstract:The seismic performance analysis of a super high-rise shear wall structure with high-position connected structure was introduced in detail. Based on the engineering characteristics and out-of-code conditions, the performance-based seismic design was proposed for the vertical members and key connectors of members. For the whole structure, considering vertical seismic action, elastic and non-yielding designs under fortification earthquake were conducted. In the case of frequent earthquake analysis, YJK and SATWE were used to calculate the results. The results show that the vibration cycle of the structure is reasonable and meets the regulations of the code. The dynamic elastic-plastic analysis was carried out with MIDAS/Building to study the influence of the connector body on the mechanical properties of the structure and the failure mechanism of the shear wall structure with high-position connected structure. The ANSYS was used to conduct finite element analysis of the connection node. The results show that the connection node could satisfy performance design goals, and finally the structural feasibility of rigid connectors in the super high-rise shear wall structural system is demonstrated.
Keywords:super high-rise shear wall structure; high-position connected structure; performance-based seismic design
