强台风地区大跨度仓储结构优化设计方案

Optimal design scheme of large-span storage structure in strong typhoon area

针对强台风地区大跨度仓储结构压型金属板屋面系统易被台风破坏的问题,对网架、门式刚架、混凝土框架及其相应的屋面设计方案在强台风地区集装箱码头拆装箱仓库设计中的优劣进行比较。结果表明,以网架板做屋面系统的网架结构设计方案同时具有抗台风能力强、适用跨度大、造价较低且施工质量易得到保证等优点,是强台风地区最具竞争力的大跨度仓储结构设计方案。

Aiming at the problem that the roof system of large-span storage structure with profiled metal sheet is easily destroyed by typhoon in strong typhoon area,we carry out the comparative study on the advantages and disadvantages of space truss,light-weight building with gabled frames,reinforced concrete frame structure and their corresponding roof design schemes in the design of container freight station warehouse on container wharf in strong typhoon area.The results show that the design scheme of space truss structure with the roof system of space truss slab has the advantages of strong typhoon resistance,large applicable span,less cost,and easy construction quality assurance,which is the most competitive design scheme of large-span storage structure in strong typhoon area.
