ABSTRACT
This chapter focuses on mechanical performance of tubular joints with a brief summary of their advantages and limitations. It provides discussion of research insufficiency of Carbon Fiber Reinforced Polymer reinforcement and some possible further investigation research spots. Tubular joint has been widely applied on various engineering structures, ranging from offshore platform jackets, truss-type structures of civil engineering, bridges, and ship loaders to crane structures. Tubular joints are connection regions between different Circular Hollow Section members, which are identified as crucial components in tubular structures. Many tubular joints are required to be reinforced in advance or repaired after damage because of their increasing load demands or decreasing mechanical performances. According to the classification of structural form, tubular joints can be divided into various shapes, such as Y-joints, K-joints, X-joints, and DT-joints. Grouted clamp is a utilized and advanced technique for tubular joints reinforcement. The function of grouted clamps is to reinforce tubular static strength or fatigue endurance.
