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。
Introduced a steel truss frame in the process of transformation due to increased load caused by the lack of capacity, the design does not change the stress diagram and the use of space under the circumstances, by increasing the cross-section method to reinforce the reinforcement and pointed out that the construction should be noted matter.
