Study on seismic performance ofa six-tower connected structure
The"Three Museums and Three Centers"project in Changle District,Fuzhou City.It comprises one basement and an above-ground structure that is a conjoined construction of six independent single towers(ranging from four to five floors),with the towers intercon-nected at the top.The bottom towers utilize a cast-in-place reinforced concrete frame-shear wall structure,while the connecting struc-ture of the top two floors employs a steel truss design.The structure exhibits various irregularities,including torsional irregularity,discontinu-ity in floor slabs,discontinuity of vertical components,and abrupt changes in size,classifying it as a particularly irregular structure.Taking this project as an example,this article employs the earthquake-resistant design approach and utilizes the YJK-Paco software to conduct an elastoplastic analysis of the model.It compares the dynamic characteristics of both the single-tower model and the multi-tower model,analyzing the force transmission paths and characteristics of the conjoined structure.Through time-history analysis under rare earthquake conditions,the working state of key components under strong earthquakes is understood,ensuring that the performance of the critical compo-nents of the conjoined structure remains uncompromised.This study provides valuable references for complex connection projects involving multiple towers of this kind.
