摘要
以试验为基础,研究了装配式大板结构竖向齿槽接缝在反复荷载作用下的受力过程,分析了竖缝的抗震性能及受力机理。认为竖缝最大承载力随接合筋直径的增大而增大,与接缝宽度几乎没有关系;反复荷载作用下,竖缝抗剪能力降低。提出了竖缝抗剪承载力计算公式,并对试验值与计算值进行比较,二者吻合较好。
A study based on experiment of eighteen specimens on the seismic behavior and mechanical mechanisms of vertical alveolus connections in prefabricated panel structures is carried out under repeated cyclic loading.The test process is studied,and the seismic behavior and mechanical mechanisms of connections are analyzed.Conclusions are that the shear resistance of vertical connection increases with connecting rods,but which does not change with connection width,and which decreases under repeated loading.The shear resistance formulas are proposed.The calculated results based on proposed fromulas are good agreement with the test results.
