Structural Behavior of Recycled Aggregate Concrete Elements

Abstract

This chapter focus on the basic structural behavior of recycled aggregate concrete (RAC) components, which includes the bending and shear behavior of RAC beam, the flexural and shear behavior of RAC semi-precast beam, the flexural behavior of RAC gradient slab, the punching shear behavior of steel fiber reinforced RAC slab, the behavior of RAC column under eccentric compression. The suitability of the code formulae to calculate RAC’s bending and shear capacity was verified, and based on this, a reliability analysis for RAC elements was carried out, investigating RAC beam bending moment and shear capacity reliability, analyzing the cracking patterns, deflections, bearing capacities of U, and C-typed semi-precast beams, studing the gradient slabs through experiment and the FEM analysis, analyzing the effectiveness of both recycled aggregate replacement percentage and steel fiber volume ratio when it refers to the punching shear of the slab, and carring out the reliability analysis of RAC column under axial compression and eccentric compression loading.
