摘要

本文将抗震消能支座等效线性化为Ｋｅｌｖｉｎ元件。推导了抗震消能支座连续梁桥的振动微分方程，分析了抗震消能支座连续梁桥的地震响应。在分析计算过程中采用了加速迭代法，提高了计算效率。算例计算结果表明，采用抗震消能支座后，明显改善了连续梁桥的受力特性。
n this paper, the earthquake resistance-energy dissipation(ERED) bearing is equivalently simplified as the linear Kelvin component, and the vibration differential equations of continuous beam bridge used ERED bearings are dened. Then, the earthquake response of continuous beam bridge is analyzed. In this process, the accelerated iterative method is adopted in order to promote computational efficiency. At the end of the paper, numerical example is developed to illustrate that the property of continuous beam bridge is greatly improved by using ERED bearings.
