摘　　要：由于铺设设备管线的需要,某地下车库框架梁端布置双排多个孔洞。孔洞破坏了混凝土框架梁的受力机理,特别是端部开孔使梁端塑性铰区域受力变得复杂。通过对一根梁端部开孔的框架梁检测及有限元分析,研究开孔对框架梁的承载力的影响。最后根据检测及分析结果,提出技术处理方案。As a result of the need of laying pipeline equipment, underground garage frame beam end is decorated more than double row holes. Holes destroy the working mechanism of concrete frame beams, especially the end open hole that the percussive force is complicated by the plastic hinge region. By a tie-beam opening frame beam test and finite element analysis, study the effect of hole on the bearing capacity of the frame beam. According to the test and analysis results, and puts forward technical scheme.
