钢梁—钢筋混凝土柱框架节点抗震性能试验研究

试验设计制作了两个钢梁-钢筋混凝土柱框架中间层中节点试件,水平加载装置采用MTS力学加载系统,对结构试件施加低周反复荷载。在节点区的型钢腹板、翼缘和箍筋上预埋应变片,用以观测节点区的应力应变状态。通过在节点区的梁端上下翼缘处布置拉杆传感器观察钢梁的受力过程。利用MTS自身配置的数据采集系统对结构试件的力和位移等信息进行采集和分析,研究表明:钢梁-钢筋混凝土柱节点有利于结构抗震,同时具有较强的耗能能力。

Study on seismic resistance of joints made of steel beam and reinforced concrete columns

This experiment design two steel beam - reinforced concrete column specimens in the middle tier, horizontal loading device using MTS mechanics test system, applying low cyclic reversed loading on structure specimen.In the node area of steel, flange and web embedded strain gauge on the stirrup to observate the stress and strain state . Arrange sensor through up and down of the node and flange to observe the stress of the steel beam process. Use their own configuration data acquisition system (MTS) collect the information such as the force and displacement of the specimen , Studies have shown that Steel beam- reinforced concrete column joints is use for structure seismic, and at the same time has good energy dissipation capacity .
