由于钢筋的抗腐蚀性能较差,在自然环境或使用环境较恶劣的条件下,钢筋混凝土结构常因为钢筋的锈蚀而导致结构的强度失效和破坏。随着技术的发展,生产发明了抗腐蚀性能非常好的FRP筋,且用FRP筋作为混凝土结构加强筋的应用和研究,越来越引起土木工程界和学术界的重视。本研究构造一个无剪力自锁的四边形层叠板单元,以进行中厚度FRP混凝土板的非线性分析研究。Timoshenko梁函数用来构造单元的弯曲形函数。单元模型中考虑FRP筋的脆断行为,混凝土材料的非线性行为包括拉伸、压缩、开裂和拉伸强化等行为及结构几何非线性行为。运用该四边形层叠板单元,对典型的FRP混凝土板进行了非线性分析研究。将数值分析结果和实际实验室试验结果进行了比较,以验证该非线性分析的有效和正确性。
