Abstract: Logan Headquarters Center is composed of two " concrete-filled steel tube composite column frame-core tube"structural towers and steel trusses, which form multiple complex connected structure at high positions. The basic design ofthe structure and the selection of the structural system were introduced in detail. The design strategy of the structure wasdescribed comprehensively from the overall performance index of the structure, structural seismic performance target,maximum inter story displacement angle of the structure, shear weight ratio, etc. , and envelope design for the structure ofmultiple connected towers and single tower was carried out. The results show that all indicators of the structure meet therequirements of the specification, and the structure has sufficient safety redundancy.

Keywords:frame-core tube structure; conjoined structure; concrete-filled steel tube composite column; modal analysis;seismic performance objective; envelope design
