Ltd.Shanghai 200941 China) Abstract:As a new-type latticed shell structure the steel truss and dome pound spherical lattice shell adopts distribution form of the main backbone structure and sub-structure.It has sufficient space span capability with reasonable mechanical behavior and appealing design.But due to its plicated structure and maybe along with a lot of application of prestressed cable relatively plicated construction process is caused as well as high construction precision control and technical requirements and huge construction difficulties.Taking Shaoxing Jinsha Orient Sunseed International Business and Leisure Center as an example this article introduces the key technologies during the design and construction of large-span pound spherical lattice shell of steel truss and dome. Key words:steel structures;trusses;suspendome;shells;detailed design;construction. 1工程概况 绍兴金沙东方...
