The Study On Seismic Behavior And Structural Infuluencing Coefficient Of Composite Steel Frame-Reinforced Concrete Infill Wall

As a new type of brace resistant steel frame, partially-restrained connection steel fFrame-reinforced concrete infill wall(PSRCW)structural system,in which the steel and concerete components work integrally through mechanical connectors,increases the lateral stiffness of traditional moment resistant steel frame,so that provides the opportunity to use partially-restrained connections instead of more expensive fully-resistant performance in the regions subjected to earthquakes. The international and domestic research of PSRCW structural system is still in the primary stage and the structural influence factors of PSRCW is not studied.Therefore making study of the PSRCW structural system are singnificant for theory and practice.The experimental research on the composite steel frame-reinforced concrete infill wall strucure under low frequency cyclic reversed lateral loads has been completed.The stiffness,lateral bearing capacity and energy dissipationg are probidedOn the basis of the experimental results,this paper applies nonlinear finite elment method to simulate the syustem at the first time ,in which ,the five main influential factors,such as width of the infill wall compressive strength of the concrete ,reinforcement ratios,numbers of the headed studs are taking into conside.Some results are obtained.At last,the structural influnence foctors of PSRCW structural system based on tests and FEM analysis are presented...
