大跨度轻钢结构厂房施工过程中整体倒塌的结构分析

对某钢结构厂房施工过程发生倒塌事故的结构分析与计算表明,大跨度轻钢结构厂房施工中保证结构整体稳定至关重要。支撑、檩条、压杆与钢架同步安装;临时缆风是否按计算后确定的数量、位置、规格设置,是保证结构安全的关键。

STRUCTURE ANALYSIS OF INTEGRAL COLLAPSE IN CONSTRUCTION OF BUILDINGS WITH LARGE SPAN LIGHT-WEIGHT STEEL STRUCTURE

According to the analysis and calculation of the collapse accident occurring in the construction of some steel structure building, it shows that to ensure the integral stability in the construction of the light-weight steel structure building with large spans is very important. All the brace, the purlin, the pressure bar and the steel frame are installed synchronously. Under the condition that the wind strength should be calculated in the temporary cable, setting the determined amount, position, and specification is the key to ensure the safety of structures.
