摘要
苏州商服楼工程空中鱼腹式钢连廊的跨度为56.7m,距地高度为37.5、62.5m,如何确定钢连廊的结构形式是一项设计难点。本文首先对三种方案的强度、刚度、经济性能进行了对比分析,最终确定下弦双拉杆的刚接桁架结构作为钢连廊的结构受力体系;其次对钢连廊进行了构件设计、环状刚片的平面外刚度分析、支座节点设计;最后进行了楼板舒适度性能评估,期望本文能够为今后类似的工程设计提供参考和借鉴。
A fish-ellied steel gallery set in Suzhou Shangfu building project. The height of the steel gallery is 37. 5m and62. 5m off ground,which span is 56. 7m. How to determine the structure of steel gallery is complex in the design. In the first place,strength,stiffness and economic performance of three schemes were contrasted and rigid steel truss with steel rod was determined as a structure system of the fish-ellied steel gallery. Then,component was designed,stiffness out of plane was analyzed and the joint design of the steel gallery was presented. Lastly,comfort performance on floor was evaluated. This study is expected to provide reference for the similar engineering design.
