Study on Construction Technique of Complex Multi-layer Steel Structure

摘要

This paper makes a study on the stress and deformation of complex steel structure in the process of hoisting and erection combining with an actual project, to determine the proper hosting and erection techniques in order to offer references and examples for other similar engineering construction. Tianjin Gallery is one of six projects of Tianjin Cultural Center. The steel structure project has an intense time limit, complex project requirements, heavy major diameter steel pipe columns, roof steel trasses in large quantity and huge work amount. In this study, we made a computational simulation and analysis to the work progress using ANSYS to find out the weak links and key control points of work progress in advance. Meanwhile, we monitored and controlled the whole process. The actual monitoring results tally with theoretical calculation data.
