| Abstract | ||
| The upgrade plan for the next-generation HPR1000 nuclear power plants aims to fully adopt modular construction technology. Half steel plate-concrete composite (HSC) slab-to-reinforced concrete (RC) wall joints are critical connections in modular nuclear power plants, yet their failure mechanisms remain largely unexplored and limited research. This study investigates the shear and force-transfer behavior of HSC slab-RC wall joints through experiments and numerical simulation. Two connection methods were proposed and evaluated: the normal rebar-to steel-plate lap-splice (NR-SL) connection and a newly developed anchored rebar-to-steel-plate lap-splice (AR-SL) connection. Cyclic loading tests were conducted on six large-scale joint specimens, varying the tie-bar steel ratio and connection methods. Comparison results proved that the AR-SL connection has excellent force-transfer performance similar to that of the NR-SL connection, with advantages in both efficiency and cost-effectiveness. The nonlinear finite element models were used to perform parametric analysis, further clarifying the influence of the tie-bar steel ratio, lap length, location, and tensile force ratio of lapped rebars. Finally, based on the force-transfer model, a joint design method was proposed for engineering applications. | ||
