Prestressing steel tensile strip cable dome and its construction process analysis
摘要
Abstract
In order to solve the problem of the complex connecting details in rigid roofs used in con-ventional cable dome structures,a new prestressing steel tensile strip cable dome structure was put forward.Considering the characteristics of steel tensile strips,a positive construction process analysis method by establishing a pre-analysis model to determine the initial shape was proposed according to the nonlinear dynamic finite element method.Based on the roof structure in the Wuxi New District Science and Technology Exchange Center,a model for this new prestressing tensile steel strip cable dome was established.The construction process of non-bracket tow-lifting was analyzed.The results show that during the constructing process,the configuration of the prestressing tensile steel strip ca-ble dome undergoes suspension state,adjustment state and stiffening state.The forces of lifting and towing cables increase significantly when the endpoints of steel strips approach outside supports.The steel tensile strips remain elastic throughout the whole construction process,and the final configura-tion is similar to that of the ridge cable simulated by cable or bar elements,which demonstrates that the new structure is feasible.关键词
