| Abstract: | A type of novel shear connectors for steel-concrete-steel(SCS)composite wall were reported.By using the SCS composite walls with C-channel connectors,the axial compression tests of six specimens were carried,the influences of shear connectors spacing and concrete material on the compressive behaviors were studied.The results show that the arrangement of connectors and material properties of concrete have a great influence on the compressive behaviors of SCS composite walls.The greater spacing of shear connectors reduce the ultimate capacity and the ductility of SCS composite wall,but has little effect on the initial stiffness.Ultrahigh performance concrete(UHPC)can significantly improve their compressive resistance and initial stiffness,but reduce the ductility as well.Meanwhile,by comparing the experimental values with the theoretical values based on the Chinese standard and the European code,it is found that the load capacity design formula based on European code is safer. |
