| 摘 要： | 为了研究贯穿钢筋直径对波形PBL连接件极限抗剪承载力的影响,设计了贯穿钢筋直径分别为16 mm、20 mm和25 mm三组PBL连接件推出试验试件,通过使用5 000 kN的加载试验机对试件进行加载试验,测量出试件中工字钢与混凝土板之间的相对位移,并绘制出试件的荷载位移曲线.试验结果表明,当贯穿钢筋直径从16 mm增加到20 mm时,波形PBL连接件的抗剪承载力随着贯穿钢筋直径的增加而提高,当贯穿钢筋直径从20 mm变到25 mm时,波形PBL连接件的抗剪承载力虽在增加但增幅明显下降.

| Abstract: | In order to study the influence of diameter of through rebar on the ultimate shear capacity of corrugated PBL shear connector,a test specimen is designed for the three groups of PBL connectors,which are 16 mm,20 mm and 25 mm of diameter of through rebar,meanwhile,vertical load to text specimens is applied through 5 000 kN-loading test machine,relative displacement of I-beam and concrete plates is measured,and the load-displacement curve is plotted.The text results shows that,the ultimate shear capacity of corrugated PBL connector increases with the increase of the diameter of rebar.But when the diameter of the rebar increases from 20 mm to 25 mm,the increasing rate of the ultimate shear capacity of corrugated PBL connector is obviously reduced. |
