The Finite Element Simulation Analysis of HPFL Reinforced Concrete Slab-Column Structure

High performance ferrocement laminate (HPFL) reinforcement method is used in this paper to make a finite element analysis on mechanical properties of five reinforced slab-column members. The analysis shows that the bearing capacity of reinforced slab columns and rigidity of midspan slab band have been improved accordingly. Furthermore, with different layout types (field type, groined type and, cross type) of steel mesh in reinforced layer, reinforcement effect and mechanical behavior of reinforced columns can be different. On the premise that punching shear resistance of original columns is strong enough, cross-type reinforcement is the best bending resistance reinforcement pattern of the best reinforcement effect with field-type reinforcement as the second. A reasonable selection of reinforcement pattern shall be made on the basis of the structure’s own mechanical characteristics while a reasonable reinforcement pattern can both ensure the effect of reinforced columns and cut the costs. Conclusions of the paper are supposed to provide some references for reinforcement design in practical engineering.
