型钢混凝土梁、柱节点试验研究

Experimental study of joints of steel reinforced concrete beams and columns

依据在建和已建工程中采用的型钢混凝土节点性能,通过单轴施加荷载研究型钢混凝土柱与钢筋混凝土梁、型钢混凝土柱与型钢混凝土梁节点性能,并依据工程特点分析了采用钢筋连接器和传统连接方法在性能上的差异,进行了3个1∶2模型节点整体试验。通过试验研究得出型钢混凝土梁节点(SRC-SRC)和钢筋混凝土梁节点(SRC-RC)的承载力等各项性能;得出了在其他条件相同的情况下,采用钢筋连接器与不采用连接器的节点的对比性能,为型钢混凝土梁、柱节点的合理设计以及施工中钢筋连接器的合理使用提供了依据。

The development history of steel reinforced concrete structures and research status in our country were desrcibed.Basing on the constructions that been built and building,3 joint specimens of steel reinforced concrete beam and column with ratio of 1 ∶ 2 were designed.The specimens were subject to uniaxial load.Through the test,the paper obtain the performances of bearing capacity and deformation capacity for the joints of steel reinforced concrete beam and steel reinforced concrete column(SRC-SRC) and reinforced concrete beam and steel reinforced concrete column(SRC-RC).At the same time,the comparative performances of using rebar connectors were researched,and not using rebar connector in joints in the case of other conditions.The study provides a support for the rational design of joints for steel reinforced concrete beams and columns.
