Experimental and numerical performance analysis of alccofine-based crumb rubber concrete under quasi-static cyclic load

Abstract

Structure, during its design period, may face unpredictable dynamic loading: wind, earthquake, and blast. Unavoidably, loading rates impact the dynamic behaviours of structures. Besides, the infrastructure system is more susceptible to dynamic loading. Therefore, a study on the dynamic behaviour of concrete under quasi-static cyclic load is inevitable. Fortunately, the researchers explored that innovative materials could respond better to extreme dynamic loading. One of the serious issues is the demolition of rubber tyres, which may be solved by converting the same into crumb form as an innovative construction material. In the present study, experimental and finite element method-based numerical analysis shows a substantial improvement in fatigue, flexural, ductility, inelastic performance, and energy dissipation capacity of the alccofine-based crumb rubber concrete beam. These performances are observed experimentally under monotonic and quasi-static cyclic loads. The load-carrying capacity has also been predicted analytically; the results agree with the experimental and numerical ones.
