Description
技术领域technical field
本发明属于建筑技术领域，特别是涉及一种抗爆耗能轻钢结构柱。The invention belongs to the technical field of buildings, in particular to an anti-explosion energy-consuming light steel structural column.
背景技术Background technique
在我国，轻型钢结构多用于单层、多层厂房、2~3层的轻型钢结构宾馆、办公楼、以及地震灾区的多层民用住宅建筑等。 然而，轻型钢结构建筑对爆炸冲击荷载作用比较敏感，抗爆性能相对交差。作为轻型钢结构最重要的承重构件轻钢柱，在爆炸冲击荷载作用下，抗力明显降低，一旦发生破坏，可能引起连锁反应并导致整个建筑结构的跨塌。因此，轻钢柱的抗爆设计十分重要。In my country, light steel structures are mostly used in single-story and multi-story factory buildings, 2-3-story light steel structure hotels, office buildings, and multi-story residential buildings in earthquake-stricken areas. However, light-weight steel structure buildings are sensitive to blast impact loads, and their anti-blast performance is relatively poor. As the most important load-bearing component of light-gauge steel structure, light-gauge steel column, under the action of blast impact load, its resistance is significantly reduced. Once damaged, it may cause a chain reaction and lead to the collapse of the entire building structure. Therefore, the blast-resistant design of light steel columns is very important.
