摘要：
By using ANSYS/LS-DYNA, nine curved steel-concrete-steel (SCS) composite panels experiments subjected to concentrated load were analyzed by finite element (FE) models. The FE models of curved SCS composite panels were established, including the hammer, steel plates, concrete, shear connectors and end plate. The FE models were verified by comparing the load-displacement curves and failure characteristic between tests and numerical simulation. The parameters influencing the ultimate strength of curved SCS composite panels were analyzed including concrete thickness, steel plate thickness, spacing and diameter of shear connectors, and rise-span ratio. It turns out that steel plate thickness decides the ultimate strength of the curved SCS composite panels. The combination performance of specimens can be improved by decreasing the spacing and increasing the diameter of shear connectors. Meanwhile, the reasonable rise-span ratio is between 1/4 and 1/3. © 2019, Editorial Office of Journal of Building Structures. All right reserved.
