Yixing Jiangsu 214231 China: 2.Beijing Construction Engineering Group Co.Ltd.Beijing 100055 China) Abstract:The library of Yixing Cultural Centre is a special building with a special lighting dome.The lighting dome applies a novelty structure which has a great span the hyperboloid single-layer shell and steel casting connection.So it is very difficult for spatial positioning and the requirements on installation deformation of ponents is strict.According to the specificity of this structure engineers use the construction technology of pre-assembly on the ground and block-installation by large crawler cranes. Moreover the finite element software is used to analyze the structure.The whole construction process is finished safely and precisely without any temporary support. Key words:steel structures;lighting domes;shells;steel casting ponents;construction 1工程概况 宜兴文化中心位于宜兴市东沈新城启动区核 心位置，包括大剧院、科技馆、博物馆、图书馆等公 ...
