Performance-Based Seismic Design and Dynamic Elasto-Plastic Analysis of a Super High-Rise Building

The structural height of the north tower of Henghe International Business Hotel and Convention Exhibition Center in Luoyang is 184m.It exceeds limit of technical specification of class B for concrete frame-core wall tall building structures.Since the height exceed the specification limit of the code the performance-based seismic design method was adopted and the dynamic elasto-plastic time history analysis was carried out in order to evaluate the seismic performance.The results show that the structure has effective yielding mechanism under rare earthquakes and can meet the design goals of the seismic performance.
