Experimental Study On Mechanical Behavior Of Recycled Aggregate Concrete Flexure-Shear-Torsion Components Under Cyclic Loading

Recycled aggregate concrete is the sustainable green concrete, and also the important direction of the concrete development.Recycled concrete for the current study focused on aspects of material properties, and little of the structural properties, especially for the Study on Mechanics Performance of Recycled Aggregate Concrete Members subjected to Bend Shear and Torque under Cyclic loading is blank. By experimental Study on two ordinary concrete and two recycled concrete specimen in this paper, Understanding and analysis of the Recycled concrete's crack distribution, damage characteristics, hysteresis, ductility, energy dissipation ability of the performance, and also the performance of ordinary concrete specimen are compared. Based on space truss model, a interaction relationship of combined torsion members is obtained. The unification theory describes the load-behavior of combined torsion members very well. Based the unification theory, a torsion bearing capacity equation of recycled aggregate concrete members subjected to bend shear and torque under cyclic loading is obtained, and through non-linear finite element analysis method to simulate the situation of the components.The studies show that Recycled Aggregate Concrete Members has better seismic performance.
