摘要

During construction, the spatial shell structure is the variable constraint structure system. In order to guarantee the construction quality and safety, its addition or disassembly scheme of temporary support must be optimized design. Based on variable constraint structure analysis method, the paper simulated and analyzed possible multiple variable constraint scheme during the long-span space reticulated shell structural construction, and put forward the principle and method abide by addition and disassembly design of temporary support. For other variable constraint structures similar to the spatial shells, the principle and method proposed has a very great reference value.
