针对目前大跨度漂浮体系进行斜拉桥抗震设计过程中遇到的问题影响,本文分析了大跨度漂浮体系斜拉桥抗震设计影响因素的现实意义与影响因素内容,并提出了控制影响因素的抗震概念设计实践策略。其目的是为相关建设者提供一些理论依据。结果表明,要想避免大跨度漂浮体系斜拉桥抗震设计影响,可将纵向阻尼器设置在梁与主塔的连接处,以提高抗震设计效果。
Aiming at the problems existing in the anti-seismic design of cable-stayed bridges with long-span floating systems, this paper analyzes the practical significance and influencing factors of the factors that affect the anti-seismic design of long-span floating cable-stayed bridges and puts forward the anti-seismic Concept Design Practice Strategy. Its purpose is to provide some theoretical basis for the relevant builders. The results show that in order to avoid the influence of the aseismic design of long-span floating cable-stayed bridges, the longitudinal dampers can be installed at the connection between the beam and the main tower to improve the seismic design effect.
