Abstract
The structural responses of fibre-reinforced polymer (FRP)-strengthened steel-reinforced concrete (RC) slabs under moving-wheel cyclic loads are investigated numerically in this paper. A finite element model considering the deterioration of material properties of concrete, steel and FRP under moving-wheel cyclic loading is developed and employed for the numerical analysis. The finite element model is firstly employed to model the structural response of a RC-reinforced slab under moving-wheel cyclic load for validation of the loading procedures. Then the model is extended for numerical analysis of FRP-strengthened RC slabs under moving-wheel cyclic loads. The structural behaviour of FRP-strengthened RC slabs under static, fixed-point cyclic and moving-wheel cyclic loads is compared in this paper to examine the effect of the loading conditions.
