HPFL加固混凝土板柱结构的有限元模拟分析

通过高性能水泥复合砂浆钢筋网薄层（HPFL）加固法对5个不同钢筋网布置方式加固后的板柱构件的力学性能进行了有限元模拟分析。分析结果表明,经不同方案加固后的板柱构件的承载力和跨中板带刚度都有了不同程度的提高,且随着加固层钢筋网布置方式（田字形、井字形、十字形）的不同,加固后的构件呈现出不同的加固效果和受力性能;在原构件抗冲切能力足够强的前提下,十字形加固方式为加固效果最好的抗弯加固方式,田字形加固方式其次。

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

Made a finite element analysis on mechanical properties of five reinforced slab-column members of differ- ent steel mesh arrangements through high performance ferrocement laminate （HPFL） reinforcement method. The analysis shows that the beating capacity of reinforced slab columns and rigidity of midspan slab band are improved differently by the schemes, and with the different layout types （‘田＇ type, ‘井＇ type and cross type） of steel mesh in reinforced layers, the reinforced members appear the different reinforcement effects and mechanical behaviors. On the condition of the punching shear resistance of original columns strong enough, the cross-type reinforcement is the best bending resistance reinforce- ment pattern and the ‘田’ type reinforcement is the second.
