【摘要】 通过对 12根钢筋混凝土梁的斜截面抗剪试验 ,研究了采用外加螺栓箍筋、梁侧膨胀螺栓固定钢板、梁侧粘贴钢板网、外贴 U形碳纤维布对梁进行抗剪加固的效果 ,并与未加固的钢筋混凝土梁作了对比 ,还对试验结果进行了分析 ,可供工程应用参考更多还原

【Abstract】 Through the test of 12 pieces reinforced concrete beam strengthened by screwed bond steel ,steel plate fixed with expanding screw , steel net with epoxy mortar and adhesing U Shape bondes carbon fiber plate on the side surface. Shear capacity of reinforced concrete beam is studied and analysed. Contrasting experiment result between strengthened and non strengthened beam.The formulas for estimating the shear capacity is put forward,which can give referance for application.Selecting suitable way to use in one civil engineering.更多还原
