对在建的某大厦拟开洞的框架大梁进行了开洞前、后的荷载试验 ,根据试验结果及有限元分析计算 ,探讨了框架大梁腹部洞口附近应力变化及分布规律 ,为该大厦拟开洞大梁的加固与否及如何加固提供了依据。
Based on the test results and the finite element analysis and calculation, the stress variation and distribution in the vicinity of the hole of the frame girder are explored, which is proposed for the building Girder reinforcement and whether or how to reinforce the basis.
