Abstract:The various structural finite element programs were used to conduct elastic and elasto-plastic analysis on overall structure and single tower of Zhengzhou Central Plains Rising Tower respectively. Design problems in structural design of the project were focused on structural system design, concept design and performance-based seismic design, especially the design of connection parts. The calculation and analysis show that the seismic performance of the structure can meet the requirements of the specifications by the reasonable arrangement of the structural system and the appropriate structural measures.

Keywords:Zhengzhou Central Plains Rising Tower； high-position connection body; performance design; anti-progressive collapse; elasto-plastic analysis
