Abstract
When designing the nuclear related reinforced concrete (RC) structures subjected to an aircraft impact, it is important to reliably evaluate the inelastic behavior of RC panels, taking into account the deformation rate of RC members. The objectives of the present study are to experimentally investigate the inelastic behavior of RC panels under high-speed loading using 1/6 scale specimens, focusing on the effects of rebar ratio and the applicability of rebar lap splices. This study consists of two parts; Part 1 describes the detailed test conditions, the results of static and high-speed loading tests of reference specimens with a typical reinforcement ratio and no lap splices as is normal in practice. It also presents the results of finite element (FE) simulation analyses. Part 2 presents the results of high-speed and static loading tests on panel specimens with reduced rebar ratio and with lap splices, and evaluates those effects on the inelastic behavior of RC panels.
