龙卷风荷载致多跨轻钢厂房结构响应的影响参数
Influencing Parameters on Structural Response of Multi-span Light Steel Industrial Building Induced by Tornado Loads
摘要
Abstract
In this paper,the on-site disaster investigation,tornado simulation test and finite element modeling analysis are carried out for the multi-span light steel industrial building that was seriously damaged in the Shengze tornado.Test parameters are the swirl ratio,the distance from the simulated tornado to the building model and the building orientation,and the finite element model focuses on the superstructure of the light steel industrial building.The wind load characteristics and structural response of the light steel industrial building under the EF3 tornado are systematically analyzed with several parameters,and the most vulnerable section of the industrial building under the tornado-induced wind load is given.The results show that under the action of tornado,the damage degree of the roof of different spans on the multi-span light steel industrial building is different,and the windward roof edge of the side span is the most seriously damaged section.The finite element analysis verifies that the tornado-induced wind pressure on this section is the largest,therefore the most unfavorable structural response is generated.关键词
