Long-Term Load Bearing Capacity of Reinforced Concrete Coupled with Poromechanical Model for Alkali Silica Reaction
The purpose of this study is to discuss the long-term load bearing capacity of RC beams under sustained loads by using multi-scale analysis incorporating alkali-silica reaction (ASR) gel in motion through cracked concrete pores. Coupling of ASR and varying loads over the life of RC are underlined. Firstly, enhanced capacity of RC beams with coupled silicate chemical reaction and mechanical loads is investigated with different failure modes. Varying external loads over the life are also studied in considering real infrastructures subjected to soil pressure. It is computationally pointed out that alkali-silicate gels in cracks may upgrade the long-term capacity owing to arrested shear crack propagation due to crack-to-crack interaction.
