In view of the problem of morphological analysis in the construction simulation of the suspended-dome structure, an improved displacement compensation analysis method based on the model equation was adopted. The new gymnasium of Tianjin University of Traditional Chinese Medicine was taken as the research project. The lifting state of suspended-dome was obtained by using the program of APDL in ANSYS. The simulation results show that this method has a faster convergence speed and the relative error in displacement and cable force is smaller between prestressing equilibrium state and design state. What＇ s more, the discreteness of the results of the lifting state can be controlled. Through the contrast and analysis on the structural characteristics, the radial rod tensioning method which apply to the oval suspended-dome structure with discontinuous support was adopted. The prestressing tension was divided into three levels corresponding to 20%, 70% and 100% of design force. And every level was also divided into 1 - 8 steps. The whole process of construction was simulated and analyzed according to the construction method and process. The contrast and analysison the construction simulation and construction monitoring results show that the data of cable force, shell component stress, displacement of shell, displacement of support and verticality of strutsfrom experiments agree well with theoretical values of construction analysis.
