【摘要】 基于实验研究和理论分析结果,对纤维增强复合材料(FRP)约束混凝土柱抗震性能研究中存在的若干关键问题进行了探讨,包括FRP约束混凝土构件在往复荷载作用下的受力特点、破坏特征、荷载-位移关系、弯矩-曲率关系、耗能及延性变化规律等,最后重点探讨了FRP约束混凝土柱在往复荷载作用下的刚度特性。更多还原

【Abstract】 Based on the test results and the theoretical analysis,several problems in the hysteretic behavior of FRP-confined concrete columns are discussed in this paper,such as mechanical behavior,failure modes,load-deflection relations,moment-curvature relations,energy dissipation and hysteretic models.The bending modulus and the rigidity degeneration of such confined columns are also discussed.更多还原
