摘要
GFRP筋具有较好的力学和耐腐蚀性能,被作为钢筋的替代材料应用于岩土工程等腐蚀性很强的混凝土结构中。通过GFRP筋现场纵向拉伸试验,分析其应力与应变、变形的关系,研究其基本破坏形态,并建立不同直径GFRP筋材的抗拉强度的公式。
The glass fiber reinforced plastic （GFRP） rebar, which has good mechanical properties and excellent corrosion resistance, is used as an alternative reinforcement material in geotechnical engineering, such as highly corrosive environment. Through the tensile test of GFRP rebar, the stress-strain and stress deformation curves are discussed, the tensile strength formula for GFRP rebar in various dimensions is obtained by studying the damage patterns.
