Abstract: The height of-Kungang Technology Building is 219.3m, the concrete-filled steel column frame and concrete-encased composite corewall and outrigger truss system is adopted. To enhance the lateral-force-resisting stiffness, owtrigger trusses and belt trusses are used at mechanical story and refuge story. The key parts and key members were precisely analyzed by finite element software. Elastic and elastic-plastic time-history analysis were provided to implement the seismic performance objective and multi-line to defend earthquake.

Keywords: performance objective; outrigger; strengthened story; columns beyond several floors; concrete-filled steel tube
