利用玻璃纤维增强聚合物(GFRP)筋取代钢筋作为混凝土结构增强筋可以有效解决侵蚀环境下钢筋锈蚀问题，但存在着延性不足的问题，结构常常呈脆性破坏。研究了 GFRP 筋高韧性水泥基复合材料(ECC)梁的抗弯性能，并与 GFRP 筋普通混凝土梁和钢筋混凝土梁进行对比，结果显示 GFRP 筋 ECC 梁在抗弯承载力和延性方面均优于 GFRP 筋普通混凝土梁，并且 GFRP 筋 ECC 梁具有类似于钢筋混凝土的塑性破坏特征，不同于 GFRP 筋普通混凝土梁的脆性破坏。GFRP 筋与 ECC 具有良好的协同工作能力，并且两者均具有优异的耐久性能，因此在海洋工程、冬季撒除冰盐的公路与桥梁工程等领域具有广阔的前景。

Using glass fiber reinforced polymer (GFRP)bars instead of steel reinforced concrete can effectively solve the problem of steel corrosion,but GFRP bars reinforced concrete exists the problem of insufficient ductility,as a re-sult of brittle failure.This paper investigates the flexural behavior of GFRP bars reinforced engineered cementitious composites (ECC)beams,and compares it with GFRP bars reinforced ordinary performance concrete and reinforced concrete beams.The results show that GFRP bars reinforced ECC beams are obviously superior to GFRP bars rein-forced ordinary performance concrete in the bending strength and ductility,and GFRP bars reinforced ECC beams present plastic failure which is different from brittle failure that GFRP bars reinforced ordinary performance concrete beams present.GFRP bars and ECC have good ability of collaborative work,both of which have excellent durability, therefore,they have broad prospects in the field of marine engineering,road and bridge engineering which may experi-ence deicing salt.
