Analysis on the Design of complex high-rise structure with large chassis and twin towers in Xiamen
Xiamen Jiali Plaza project is a complex building.In order to fully realize the functional requirements of the building,the structure is not broken,and there is no post-pouring belt,forming a large chassis and twin tower building.The structure has many irregularities,such as multi-tower,torsional irregularity,floor discontinuity,dimensional mutation,tower bias,local inclined column and through-storey col-umn,and large span.A variety of software and a variety of models were calculated and compared in the design,and the changes of each in-dex of the whole model and the sub-tower model were compared emphatically.Through the combination of concept judgment and calcula-tion analysis,the key and weak parts of the structure were targeted to take measures,and the structure achieved the expected seismic per-formance target by SAUSAGE dynamic elastic-plastic time history analysis.This paper analyzes and summarizes the main problems in structural design for reference of engineering and technical personnel.
