摘要
玻璃纤维复合材料(简称GFRP材料)凭借质量轻、强度高以及耐腐蚀等优势,在工程中得到越来越广泛的应用。其连接性能是结构设计的重要一环,实际工程中常采用钢套管连接形式。对于Φ200×10规格钢套管的连接性能进行研究,为了避免"尺寸效应"的影响,试件均为足尺模型。通过试验装置,对其轴心抗压与抗拉性能进行研究,得到了GFRP复合钢套管的荷载-位移曲线和应变分布规律,分析了其极限承载力、变形能力和破坏形式的影响因素。
Glass fiber composite material（ Referred to as the GFRP material） with light weight,high strength,corrosion resistance and other advantages has been more extensively used in structure engineering,whose connection properties for the whole structure are very important,for instance steel casing connection is often used in the practical engineering. In this paper,the tensile and compressive resistance connection property of the Φ200 × 10 with steel casing bonding are studied. In order to avoid the ＂size effect＂,specimens are full scale model. The axial compression and tensile properties of the device are studied by means of test device,so as to obtain the load-displacement curves and strain distribution of GFRP composite steel casing,and the ultimate bearing capacity,deformation capacity and failure modes etc. are analyzed.
