Construction technology analysis of space heterotypic steel frame of concert hall in Changsha

摘要

Many heterotypic steel frames with special-shaped are used in the concert of Changsha. It causes difficulties to the construction technology. Based on the characteristic, It is studied the construction process, then put forward the subsection lifting technique, applied energy analysis method for lifting point and used finite element analysis for supporting system. At the same time, it is used measuring robot 3d positioning method and elaborated the operation points, At last, it is analyzed the welding technology. All of these provide guarantee to the smooth construction.
