玻璃厂门式刚架轻型钢结构厂房的加固

门式刚架轻型钢结构厂房的受力模型同实际情况比较吻合,因此能够在设计中充分利用钢材的受力特性,具有非常经济合理的效果。但同时其安全储备相对较低,如果在施工阶段出现较大的质量问题或在使用中外部荷载和作用发生变化,则刚架就易处于不安全的状态而必须进行加固才能保证安全使用。该文通过2个工程实例讨论门式刚架厂房加固常用的方法。

Strengthening of Portal Frame Light Steel Structure Workshop Building in Glass Plants

The bearing model of portal frame light steel structure workshop building is relatively consistent with the real situation,therefore,it has much reasonable economic effect if it is possible to make sufficient use of steel bearing characteristics during the design,but at the same time its safety margin is relatively low.If serious quality problem appears during construction stage or external load & function change during its usage,the frame is liable to unsafe condition,so that it has to be strengthened for the safety purpose.The paper discusses the normal method for strengthening of portal frame workshop building through 2 engineering examples.
