Abstrait:

In order to improve the support and isolation performance of the escape cable-stayed bridge with super wide A-type tower in high-intensity areas, the paper takes Jingyuan Jinshatan Yellow River Bridge as the background, based on the finite element method, and takes the design of 20000 ton isolation bearing as the case, optimizes the design parameters, structural composition and friction pair settings of the bearing, and develops the actual bearing to meet the needs of the project by combining simulation analysis and experimental testing. The results of time history analysis show that the displacement of the strength support seat at the bottom of the pier and the expansion joint at the beam end can meet the design requirements.
