( Shanghai Institute of Architectural Design ＆Research Co., Ltd., Shanghai 200041, China)Abstract: The citizen senuce center of Caofeidian is a conjoined structure with four towers. Computational analysis and design principle of the special structure were introduced. The design load and effect, the consideration of concrete slab in the steel structure design, the vibration comfort of the floor, the stiffness degradation of concrete structure were discussed, which can be reference for similar projects.
Keywords: conjoined structure; large-span steel truss; envelop design; vibration comfort; stiffness degradation
