摘要
针对东海大桥主桥的抗震性能进行分析研究,基于两水准设防、两阶段的抗震设计思想,对主桥进行了抗震分析。同时考虑了支座的非线性、拉索的几何非线性和墩柱的非线性等对结构抗震性能的影响。研究结果表明,东海大桥主桥的抗震性能满足预期的设计性能目标。
The analytical study of the aseismatic performance of the main bridge of Donghai Bridge is presented. The aseismatic performance of the bridge is analyzed on the basis of two levels of seismic protection and two stages of aseismatic design. The effect of non-linearity of the bearings and pier columns, and of geometric non-linearity of the stay cables upon the aseismatic performance of the bridge structure is also considered in the study. The study results indicate that the aseismatic performance of the main bridge of the Bridge can meet the expected design goal.
