In this paper, the structural optimization and safety of double-car high-speed elevators in super-high-rise buildings are studied, taking the double-car high-speed elevators in the green center Twin Towers project as the research object. Firstly, the connotation and characteristics of double-car high-speed elevator are introduced. Then, the key factors affecting the carrying capacity and safety of the elevator are analyzed, including structural design, material selection, safety system and quality control. Through the case analysis of the green center Twin Towers project in Zhengzhou, this paper expounds the application of the project in the configuration, main difficulties and technical measures of the double-car high-speed elevator and its achievements. Then, the measures to improve the bearing capacity and safety of double-car high-speed elevator are put forward, which are mainly expounded from three aspects: structural design, material selection and structural analysis and prediction.
