摘要:
门式刚架轻型房屋在我国低层大开间建筑中应用广泛．近年来，我国灾害频发，门式刚架房屋受损较严重，给国民经济造成巨大损失．分析原因：一方面作为一种轻钢结构，抗灾害能力较弱；另一方面，人们对门式刚架房屋的防灾减灾意识不强．针对上述情况，本文系统总结了雪灾、风灾、火灾以及地震对该种结构的破坏形式，分析了破坏原因，并提出了具体的设计对策，针对灾害破坏下门式刚架规范的修订及安全问题进行总结分析．同时，提出了“门式刚架屋面抗火性能及防护措施”和“门式刚架房屋局部倒塌引起的连续倒塌机制及防连续倒塌设计”两个新安全问题，希望引起相关人员的重视，进而推动门式刚架房屋防灾减灾工作的发展．
Abstract:
The light-weight portal frame houses were widely used in low layer and large bay building in our country. In recent years, China has suffered many natural disasters, causing more damage to this kind of architectural form. On the one hand, as a kind of light steel structure form, the anti-disaster ability is weak; on the other hand, people didn’t have a strong awareness of disaster prevention and reduction on the light-weight portal frame. This paper summarizes the snowstorm, windstorm, fire and earthquake damage to this kind of structure, and analyses the reasons. In view of the above situation, the paper summarizes the snowstorm, windstorm, fire and earthquake failure models to this kind of structure, and analyses the reasons. On this basis, the safety counter measures of portal frame is reviewed, and the revision of the specification and the key of structure design of portal frame under the disasters is analyzed. Meanwhile, the paper put forward two safe questions: 1. the fire resistance performance and protective measures of the roof of portal frame” and 2. the continuous collapse mechanism caused by the local collapse and design of portal frame in the hope of. causing the attention of people, and promoting the development of portal frame building disaster prevention and reduction
