| Abstract: | The paper concerns the installation of 67.2 m long-span roof trusses for a high-tech factory. Because of the limited project site and economical conditions, using large capacity machines to directly lift steel trusses isn＇t feasible. A finite element method is proposed to obtain a good hybrid lifting construction scheme for the heavy and long trusses. The lifting scheme making good use of a truck crane and elevated gantry cranes, greatly increase the work efficiency of roof truss installation, and as a result total seven long trusses have been rightly positioned within two weeks. |
