Deflection Control of One-Way Reinforced Recycled Aggregate Concrete Members

Abstract

A parametric analysis of deflection control of reinforced recycled aggregate concrete (RAC) one-way members is presented in this study. Within the study, member boundary conditions, ambient conditions (relative humidity), reinforcement ratios, and quasi-permanent–to–design load ratios (as per the Eurocode framework) are varied. Through the analysis, the change in deflections is observed relative to the substitution ratio of RCA (from natural aggregate concrete, NAC, to RAC with 100% of coarse RCA) and span-to-effective depth ratio (L/d). The results of the analysis enable a clear overview of the variability of the deflections of RAC members relative to NAC.
