开孔波形板剪力连接件推出试验研究

Experimental research on the shearing connector of open-hole and wave-shape plate for the promotion

通过对设有双开孔波形板剪力连接件的试件进行推出试验,探讨了这种连接件在外荷载作用下的钢板和混凝土应变分布及荷载滑移变化规律,分析了混凝土板与钢板交界面的界面特性及贯穿钢筋的受力情况、混凝土板的掀起作用等,结果表明:开孔波形板剪力连接件具有较高的抗剪能力和连接性能,混凝土与钢梁交界面相对滑移量小。

Through carrying out the promotion experiment of shearing connector of double-open-hole and wave-shape plate, the paper explores the strain distribution and load sliding law of steel plate and concrete under the external load of connectors, and analyzes the interface characteristics between concrete plate and steel plate interface and the stress conditions of crossing steel and the lifting role of concrete plate and so on. Results show that： shearing connectors of open-hole and wave-shape plate has higher anti-shearing capacity and connecting performance, there is little sliding amount of the interface between eonerete and steel beam.
