摘要
设计、试验了 18榀试件 ,分析了装配式大板结构竖缝在反复荷载作用下的抗剪机理 .爆裂前 ,接缝的抗剪机理为斜压杆机制和压力摩擦机制 ,抗剪承载力随接合筋直径的增大而增大 ;爆裂后 ,抗剪机理为削弱的斜压杆机制和接合筋的销拴作用 ,抗剪承载力随接合筋直径及接缝宽度的增大而增大 .
specimens are designed and tested,the shear resistance mechanisme of vertical connections in precast reinforced concrete structures under repeating cyclic loading is analyzed. The shear resistance of vertical connection before sudden cracking is diagonal compressive rod mechanism and compression friction mechanism;the bigger the diameter of connection rod,the stronger the resistance.After sudden cracking,the mechanism is weakened diagonal compressive rod mechanism and dower action of connection rod;the bigger the connection rod and connection width,the stronger the resistance.What′s more,equations based on above mechanisms are accordance with test result.
