Abstract

Abstract

Half steel plate concrete composite (HSC) structures are a kind of structural form developed on the basis of steel structures and concrete structures. Compared with ordinary reinforced concrete structures, they have the characteristics of high bearing capacity, good tightness, good impact and explosion resistance, with great application prospects in the fields of nuclear power plant containment shells and roof panels. However, at present, the connection type of tie bars has not been clear, and the impact resistance of different types of tie bars have not been studied. In order to investigate the influence of different structural forms on the failure mechanism and impact resistance of tie bars in actual engineering, the HSC target panels with a scale ratio of 1∶20 and 1∶10 were designed respectively, with three types of tie bar connections. Dynamic impact tests were carried out, and the force mechanism as well as failure modes of different tie bar connections were revealed under dynamic impact load. The results showed that the failure modes of HSC target plates under local impact were mainly bulging and penetrative. The local failure phenomenon was more obvious with the increase of kinetic energy of projectile body. The main factor affecting the failure mode was the plate thickness, followed by the impact velocity. The application of end anchor structure is more beneficial to control the deformation in the impact area and the dynamic response peak near the impact area.
