| Abstract: | Installation of large-span roof trusses is a controlling step in construction procedure of Winter Garden building in Shanghai International Transportation Center.And a reasonable installation scheme for the step is needed.According to characteristics of structure and conditions of construction site,integral lift technology was used for installation and the scheme was made.Based on the three-dimensional finite element method and incorporating the mechanic properties of the Q345B steel used for the structure,simulation analysis model was established using Bernoulli-Euler beam elements.Structural responses of each installation step were then calculated.It is shown by the results that the installation scheme is reasonable and feasible. |
