50米T梁吊装过程中的稳定性分析

Analysis on Installing Stability of 50 m T-Beam by Direct Lifting

结合工程中50米T梁的一般构造,运用薄壁杆件理论分析了在吊装过程中断梁的原因,并通过有限元软件模拟吊装时的工况来做进一步仿真分析,提出避免断梁事故发生的措施,为T梁的设计和施工提供理论依据。

This paper analyses the dominant reason of beam fracture by the theory of thin-walled bar combined with the 50m T-beam structure. In order to avoid the fracture it applied the way of finite element to simulate the lifting situation and proposed the concened mensures.
