Finite Element Analysis of Friction Coefficient on Recycled Concrete Wall-Beam Interface

Abstract:

Mechanical testing on the first group of ordinary brick wall-beam and second group of recycled brickbat concrete wall-beam, measured its ultimate load and the maximum deflection, establishing finite element model to analyze, and comparing with the test results. It will be show that under the action of ultimate load, friction coefficient between the upper-wall of the wall-beam and joist can be desirable between 0.35 ~ 0.45, and the friction coefficient of recycled concrete wall-beam is bigger than ordinary wall-beam, and the higher the intensity of the upper-wall is, the bigger its friction coefficient is, as well as the greater stiffness of the wall-beam is.
