ABSTRACT

This paper presents experimental results of bending test of composite beam made of recycled concrete slab and glue-laminated bamboo (glubam) beam. Two types of shear connectors, which are commonly used in timber concrete composite (TCC) beams, were used for the test. The load/mid-span displacement curve, strain distribution curve at the mid-span section of the composite beam, and the load-relative slip curve of the composite beam were obtained. The relevant mechanical properties such as the maximum bearing capacity and the flexural stiffness of the composite beam are also obtained. Analysis and comparison of the results show that the failure mode of the composite beam with screw-connector is a delamination cracking failure of the glued bamboo beam while the beam with notch connection showed a flexure tensile failure. And use of recycled aggregate concrete is viable for bamboo-concrete composite beam.
