Abstract: The Phoenix Place is an enlarged base multi-tower complex tall building which is irregular both in plane and elevation. According to the owner's request on building function and construction progress, seismic joints are set between the towers and the podium to make each one remain a separate structural unit. This article gives a brief introduction of the selection of ground treatment and floating treatment, the selection of main structural style and integral structural analysis, and gives a reference value for similar projects.
Keywords: enlarged base multi-tower; CFG pile; seismic joints; time-history analysis
