| 摘 要： | 玻璃钢(FRP)筋防腐混凝土是一种强度高、全方位耐腐蚀的新型工程材料,具有十分广泛的应用前景.本文先对防腐混凝土梁采用四点弯曲试验方法,对FRP筋加强混凝土梁的弯曲长期力学特性进行了试验研究与分析,得到了梁在不同荷载水平作用下的蠕变曲线.结果表明,FRP筋不仅提高了防腐混凝土梁的初始刚度和强度,且明显降低了梁的蠕变变形.最后,运用最小二乘法确定蠕变模型参数,分别建立了防腐混凝土粱和FRP筋加强防腐混凝土梁的弯曲蠕变幂律模型,为估计材料的长期力学性能提供依据,对FRP筋防腐混凝土结构设计具有重要的价值. |

| Abstract: | FRP fural resin concrete which has extensive application prospect is a kind of anti-corrosive new engineering material.Although it's stronger in compression than cementitious concrete,its tension behavior is weak,the reinforcement of polymer concrete beams in the tension zone with pultruded profiles made of resin and glass fibers are a good compromise between strength and stiffness.In this paper,firstly the experience has performed about the bending and creep characteristic of non-FRP reinforced furan resin... |
