Large Span Irregular Space Spherical Reticulated Shell Steel Structure Installation Technology

With the vigorous development of China’s economic construction,the continuous improvement of people’s living standards,large span industrial buildings,airports,exhibition center,theaters,sports venues and other large industrial and public buildings,the complex space steel structure has been an unprecedented rapid development,steel structure installation technology is improving.Taking liaoning province science and technology museum ball curtain cinema complex irregular space spherical reticulated shell steel structure for the installation of the carrier,research and analysis the feasibility and economy of different steel structure lifting scheme combines the actual conditions of the scene with the method of computer simulation,study and formulate the ball shell.The installation technology of steel structure.At the same time system research to the problem as follows:(1)Comprehensive analysis to compare alternative for spherical shell steel structure installation plan provides a best installation method.At the same time,through the finite element analysis software Midas Gen the hoisting of steel structure unit,and calculation and analysis of spherical shell steel structure of the break-up of lifting unit,make its scientific and reasonable,meet the conditions.(3)The design of temporary bearing support system in the process of installation of spherical shell steel structure,then analysis the finite element the installation component and temporary support system for each working condition are carried out by use the Midas Gen.(4)Analysis the internal and external shell steel structure of the lifting element of the field assembly and the ball shell steel structure of the whole process by computer simulation,for the ball shell steel structure installation program to provide the necessary support and guarantee.(5)Study on the development of this project Spherical steel temporary support uninstall program,and the uninstall process for steel spherical shell member and the temporary support of the stress state and deformation were calculated and analyzed by Midas Gen software.
