Simulation of concrete structures deformation affected by alkali–silica reaction considering environmental conditions and multiaxial stress state

In this study, the expansion and deformation of alkali–silica reaction (ASR)-affected concrete structures under natural environment multiaxial stress state are predicted. The performance ASR model proposed in previous research is quantitatively investigated terms relative humidity, stress, temperature dependencies based on experimental results. simulation results indicate that humidity-dependent caused by can be simulated effectively slightly modifying humidity threshold model. a focusing dependency, insufficient consideration relationship between compressive gel absorption into pores resulted discrepancies simulating dependency improved referring to rate recorded from specimens exposed real environment. An exposure experiment reinforced (RC) slab steel girders using modified show reproduce tendency three-dimensional RC slab, while improvement considering time-dependent stress-dependent phenomena should needed for long-term quantitative predictions.
