Abstract: The main structure of the wind tower in Shanghai Riverside City hight is about 180m, the high-rising hangingstructures system that consist of reinforced concrete tube and steel suspended cylindrical reticulate shell was adopted. Byoptimizing the wall layout and wall thickness of the core tube, analyzing the shape change and buckling mode of wall limbunder the second order gravity effect and horizontal load of the tube, and comparing the influence of external hangingcurtain wall on the improvement of the structure′s center of gravity to ensure that the main structure has good seismicperformance. At the same time, combined with the wind tunnel test results, the independently developed connecting barbearing was set at the bottom of the hanging structure to realize the connecting function of hinge joint, the result of analysisshow that the outcome of the joint test meets the requirements of the performance of joint design, which ensuring therationality of the joint design and the safety of the steel lattice shell of the external hanging curtain wall.
