Abstract
To investigate the influence of adding transverse ribs near the end of the precast ribbed bottom panel on the flexural performance of the concrete composite slab with precast ribbed panel (CSPRP), bending test is conducted on concrete composite slab with precast one-way ribbed panel (SORP) and slab with precast two-way ribbed panel (STRP). The test results indicate that the static performance of the SORP and STRP specimens is similar in terms of cracking load, ultimate bearing capacity, and deflection. Compared with the SORP, the bearing capacity of the STRP is higher when the component enters plasticity from elasticity. The overall performance is better and the crack distributions are more uniform. Numerical simulation is performed with the finite element (FE) analysis software ANSYS and FE results are basically consistent with the experimental results. In addition, comparison of the theoretical values with the test indicates that the formulas proposed are accurate and applicable for calculation of ultimate bearing capacity of the CSPRP.
