混凝土构件连梁在地震中起到了一种耗能的作用,对减少墙肢内力、延缓墙肢屈服有着重要的作用。介绍了连梁的变形及破坏,即延性破坏和脆性破坏,指出了使连梁设计满足强剪弱弯的原则时所必须考虑的几个问题。
The concrete beam has played an energy-dissipating role in the earthquake and plays an important role in reducing the internal force of the wall element and delaying the yield of the wall element. The deformation and failure of the connected beams are introduced, namely ductile failure and brittle failure. Several problems that must be considered in designing the coupling beam to meet the principle of strong shear weakening are pointed out.
