According to the two kinds of tension plate joint proposed for the frame drum wharf structure,through the axial tensile tests of concrete,we analyzed the ultimate tensile bearing capacity and failure mode of the I-steel joint with different flange width,the steel plate+steel bar joint with different total area and different diameters of the steel bar.The test results show that the ultimate tensile bearing capacity of I-steel joint is less than the whole section of concrete’s;the ultimate tensile bearing capacity of steel plate+steel bar joint is equal to the whole section of concrete’s when the ultimate tensile load the whole steel bar provide is greater than the ultimate tensile bearing load of the whole section of concrete;the ultimate tensile bearing capacity of steel plate+steel bar joint is higher than the I-steel joint’s,the frame drum wharf structure should adopt steel plate+steel bar joint.
