Design and Numerical Simulation on Concrete Two-Way Slab Strengthened with Partially Bonded Steel Plate

Abstract:

Taking structure strengthen of a large hotel as the engineering background, based on superposition principle, put forward the design method of concrete two-way slab strengthened with partially bonded steel plate. According to the finite element analysis, the solid finite element model is established, and then the stress, strain and deflection of two-way slab strengthened with bonded steel plate is obtained, at the meantime compared with the load test datum in situ. The analysis results show that the finite element software is a reliable tool applied to analyze the design of two-way slab strengthened with bonded steel plate. When the increasing load is larger, partially bonding steel plate strengthening has more advantage and economize than bonding carbon fiber strengthening on two-way slab, meanwhile that slab strengthened with partially bonded steel plate has better mechanical properties, strength and stiffness.
