8 concrete filled circular Cfrp-steel tubular flexural members and 2 concrete filled circular steel tubular flexural members are experimentally investigated. It is found that the load - middle span deflection curves for members with longitudinal Cfrp can be defined as the following stages: elastic, elasto-plastic and softening stage and that for members without longitudinal Cfrp is similar to that of the concrete filled steel tubular flexural members. Within the factors scope of this test, 1 layer circumferential Cfrp only has no significant influence on load bearing capacity of the concrete filled steel tubular flexural members. The ductility of the concrete filled circular Cfrp-steel tubular flexural members is better than that of the concrete filled circular frp tubular flexural members.
