In order to ensure the smooth change of cable-strut internal forces before molding cable domes, a construction optimization method is proposed, focusing on alternately lifting the inner ring and tensioning the outermost diagonal cables. The lifting height of the inner ring is first optimized for minimizing average structural strain energy in the construction process. The cable-strut internal forces and nodal displacements from simulation are compared with those from the construction method with the tensioned outermost diagonal cables. The results show that, alternately lifting the inner ring and tensioning the outermost diagonal cables can effectively reduce the cable-strut internal forces by 61.83%, avoiding sharp fluctuation of cable-strut internal forces before molding. It causes more gentle change of structural configuration with 1.43 m maximum vertical displacement difference between adjacent construction steps, and low average structural strain energy of only 55.03%, which demonstrates its remarkable optimization effect. Thus, the proposed method is applicable to the construction simulation of cable domes.
