Abstract
Nowadays, FRP-confined steel tubular columns are emerging as advanced hybrid structural members due to their efficient performance under seismic loads. Such types of double-skin tubular columns (DSTCs) usually contain two different tubular systems, the first is the inner steel tube (ST) and the second is outer FRP tube, consisting of a concrete-filled space between them. The main objective of the present investigation is to examine the dynamic response of novel FRP-electronic waste (E-waste) concrete steel tubular columns (FESTCs) having an inner ST, outer glass-FRP tube (GT), and E-waste filled between the two different tubes to propose a sustainable structural column. Five FESTC elements were fabricated and tested under quasi-static loading to examine their dynamic performance under axial compressive and lateral cyclic loadings. The effect of three variables of FESTC samples on their performance was examined in the present study including ST reinforcing ratio, compressive loading ratio, and E-waste replacement ratio. The hysteretic cycles, strain spreading, ductility, skeleton curves, stiffness behavior, dissipation of energy capacity, damaging behavior, and strength reduction of fabricated samples were evaluated and deliberated. The outcomes of the present study showed that the effect of percentage replacement of E-waste aggregates on the dynamic behavior of FESTCs was low whereas compressive loading ratio portrayed a significant influence. Moreover, the capacities of the dissipation of energy and load-carrying strength of FESTCs elements were greater as compared with DSTCs elements containing natural aggregates.
