Experimental Study on Mechanical Performance of an Oval Steel Anchorage Connector

To solve the problem that the quality of concrete poured cannot be guaranteed due to a dense distribution of steel bars in beam column joints of reinforced concrete structures, we designed an oval steel anchorage connector. The mechanical performance test was conducted for traditional 90° hooked bars and oval steel anchorage connectors on plain concrete. The results showed that the bar was pulled off and the concrete was locally destroyed in the drawing destruction. Mechanical performance of specimen with oval steel anchorage connectors is better than specimen with 90° hooked bars, while they all satisfy the requirement of related specification. The weight of the single oval steel anchorage connector is about 1.01 kg less than that of the 90° hooked bar, which greatly reduces project cost, and promotes the sustainable development of construction industry in China.
