钢筋混凝土柱托换梁的试验研究

Experimental research on the underpinned beam of steel reinforced concrete column

通过对钢筋混凝土柱托换梁节点进行承载能力试验研究,探讨了在柱表面光滑和凿毛两种界面情况下的受力特点、破坏机理,提出钢筋混凝土柱托换设计中的主要控制参数,为实际工程节点设计提供了指导。

Through testing the bearing capacity of underpinned beam joints of steel reinforced concrete column, this paper explores the stress features and their damage mechanism of smooth and coarse of column surface, and puts forward main controlling parameters in the underpinned beam design of steel reinforced concrete column, which has provided certain guidance for actual engineering joints design.
