摘要
介绍某工程钢屋架在改造过程中由于增加荷载而导致承载力不足,设计在不改变受力简图和使用空间的情况下,通过增加构件截面的方法进行加固,并指出了施工中应注意的事项。
It was introduced that the load increase in the steel roof truss recon- struction process causes lacking of bearing capacity, under the condition of not chan- ging the force diagram and used space, the roof truss was reinforced by increasing component section in the design, and the notices for the design and construction were described.
