| Abstract | ||
| Steel-Reinforced Concrete (SRC) panels with self-centering capability are increasingly applied in sports facility structures to withstand dynamic impacts; however, the interaction behavior of angle shear connectors under three-dimensional dynamic loading remains insufficiently explored, limiting optimization for impact resistance. This study analyses the dynamic 3D response of angle shear connector SRC panel systems under drop-weight impact, introducing a novel integration of self centering design into computational interaction modelling for sports facility applications. A detailed Finite Element (FE) model was developed incorporating nonlinear temperature-dependent material properties, explicit contact definitions, and realistic dynamic loading scenarios. Input parameters included panel geometry, connector dimensions, and impact velocity; outputs comprised displacement histories, connector stress distribution, and energy dissipation characteristics. Results show that self centering panels reduced residual displacement by 42 58% compared to conventional designs, with self-centering efficiencies (Ψₛ) consistently above 0.55 and reaching 0.82 under low-energy impacts. Connector stress utilization remained within ductile limits, peaking at 0.95 in the most severe cases without brittle fracture. Larger connectors decreased peak deflection by up to 12 % but increased local concrete bearing stresses by ~15 %. Elevated temperature exposure (Θ = 550 °C) reduced yield strength by 22 29 %, increasing peak displacement by 6 9 % and slightly lowering Ψₛ. Energy dissipation accounted for 58 65 % of initial kinetic energy, with 35 45 % from steel plasticity, 25 35 % from concrete damage, and the remainder from frictional slip. Boundary restraint stiffness had a more substantial influence on | ||
