摘要
本文介绍了4个以工字型钢为骨架的劲性砼梁柱节点组合体在低周反复荷载作用下的试验结果,井与普通钢筋砼节点作了比较。试验表明,劲性砼节点具有良好的抗剪能力和耗能能力。文中还论证了节点箍筋的作用和锚板锚固性能。在此基础上提出了劲性砼节点受剪承载力的设计建议,并与国内外资料作了比较。
Steel Reinforced Concrete ( SRC ) has been used in highrise building because of its excellent aseismic behaviour. In this paper, the experimental results of 4 SRC beam-column subassemblages composed of I-shaped steel subjected to reversed cyclic loading are described and compared with conventional RC joints. Tests showed that the SRC joints possess an apparent increase in shear strength and energy dissipation capacity. The effect of stirrups and plates on SRC joint has also been discussed. Based on the analysis of test data, a formula for calculating SRC joint shear capacity is presented and some recommendations on the design of SRC structure are suggested.
