摘要
由于屋面荷载增大,造成钢梁承载力不足,需要对钢梁进行加固。通过改变钢梁的结构形式,使其变成张弦梁的新型加固技术,同时结合支撑法对钢梁进行加固。该加固方法均采用机械连接,可在结构负荷状态下施工,增大了施工的方便性。结合某工程实例,介绍该加固技术,通过计算分析其加固效果,并在实际工程中得到了良好验证。
As the roof load increases,resulting in insufficient bearing capacity of steel beams,steel beams need to be reinforced.By changing the structural form of the steel beam,it becomes a new reinforcement technology of the string beam,and at the same time,the steel beam is reinforced with the support method.The reinforcement methods are all mechanically connected and can be constructed under structural load conditions,which increases the convenience of construction.Combining with an engineering example,this reinforcement technology was introduced,and its reinforcement effect was calculated and analyzed,and it was well verified in the actual project.
