Durability Experimental Method of RC Components Strengthened with FRP in Hot-Wet Environment
Taking bridge structures in service period as research objects, durability experimental method of reinforced concrete (RC) components strengthened with fibre reinforced polymer (FRP) under time-varying hot-wet environment and random fatigue load coupling/interaction was discussed and corresponding experimental system of structural components was developed and integrated.To prove the effectiveness and feasibility of the experimental method proposed, durability/environmental fatigue experiments of RC beams strengthened with carbon fibre laminates (CFL) were carried out including the following four experiments: a) non-interaction experiments (the current method) of constant temperature, constant humidity and fatigue loads, b) interaction experiments of constant temperature and humidity and fatigue loads, c) interaction experiments of real service environment and fatigue loads, d) interaction experiments of real service environment and vehicle random loads.The results showed the durability/environmental fatigue experimental method proposed by this paper was effective and feasible.
