剪力连接件静载和疲劳试验研究

Experimental Study of Shear Connector under Static and Fatigue Loading

共进行了9 只栓钉连接件和6 只带孔钢板连接件的疲劳和静载破坏试验研究, 分析了混凝土材料类型和强度等级、连接件类型、横向配筋等参数对连接件疲劳性能和极限承载力的影响,建立了相应的疲劳强度与极限承载力计算公式.

This paper briefly summarizes the results of tests conducted on 9 stud-connector push-out specimens and 6 perforated-plate-connector push-out specimens under static and fatigue loading.The test specimens were designed to study the effect of a number of parameters on the behavior of fatigue and the shear capacity of the connection.These were the type and the compressive strength of concrete,the number and the position of transverse reinforcements.The expressions of calculating the fatigue strength and shear capacity of stud and perforated plate connector are proposed.
