Research on the Rebar Connection Form and Bending Performance of T-beam Wet Joint
In view of the problems of large welding work-load,much rebar interference,insufficient construction working face and long construction period in T-beam wet joint rebar connection construction,this paper takes the wet joint structure in the reconstruction engineering of Shaoxing Donghu to Haoba section on National Highway 104 in Zhejiang Province as the research object,carries out local full-scale model tests on three connection modes of straight bar welding,double-ring overlap,and end-an-chored rebar,and analyzes the structural failure character-istics and mechanical performance of wet joints when the overlap length of rebar in different connection modes is shortened to 10d(d is the diameter of longitudinal rebar),which provides reasonable suggestions for optimizing the design of wet joints.
