摘要
本试验主要对发生脆性破坏的低强度混凝土梁柱接头构件和采用高强度混凝土增加柱截面面积加固后构件进行研究,分析梁柱接头的剪切应力衰减情况和延性,表明用增大柱截面法加固后,利用增加接头的有效抗剪面积,使接头剪切强度有效提升,使构件发生延性破坏。
The test mainly aims at the beam-column joints of low strength brittle reinforced concrete and components which is increased column section area, shear decay and ductility of beam-column joints are analyzed. It showed that the method with the increase of column section area enhanced the joint effective shear area, promoted the shear strength of joints effectively, make components occur ductile failure.
