近场地震作用下框架结构的损伤机理

A near-fault earthquake usually has the features of larger value of parameter PGV/PGA and obvious velocity pulse.

近场地震以具有较大的PGV/PGA值及明显的速度脉冲为主要特征,本文分析了不同类型的近场地震对深水桥墩地震响应的影响;采用Morison方程的基本理论,将水视为附加质量,利用有限元方法来分析动水压力对深水桥墩地震响应的影响。

The elastic displacement design spectrum compatible with the spectrum of dynamical amplification factor in the UBC97 code is calculated, and using the strength-reduction factor obtained from the regression analysis of 387 near-fault earthquake records, the non-linear displacement design spectrum based on structural damage performance is also establisked.

用387条近场地震记录通过回归分析得到了强度折减系数, 计算了与美国UBC97规范动力放大系数谱相容的弹性位移设计谱, 并建立了相应的基于结构破坏性能的非弹性位移设计谱。
