Hysteretic Behavior of Steel Members Strengthened With CFRP Under Cyclic Lateral Loading in Different Temperature

摘要

With the development of strengthening and repairing technology, carbon fiber-reinforced polymer (CFRP) has been widely applied in concrete and masonry structures for high efficiency. However, there is limited information about how they can be used to strengthen steel members. This paper presents the strengthening effect of CFRP on steel column under cyclic lateral loading in thermal environment. The results indicate that application of CFRP in steel column under cyclic lateral loading in thermal environment has substantial benefits. In particular, the CFRP wraps can improve the ultimate cyclic lateral load and ductility of steel column prominently in thermal environment which can meet the higher requirements of stiffness.
