本文应用多质点弹簧、阻尼体系模拟半无限地基的动力阻抗特性,建立上部建筑-基础-地基耦连体系在时域求解的振动方程。在此基础上考虑结构构件在强震作用下的非线性与滞回特性,进行了高层建筑地震反应的历时分析,并通过实例研究了输入地震动强度、频谱特性以及地基刚度、结构构件非线性恢复力参数等诸多因素对高层建筑地震反应的影响。
In this paper, the dynamic impedance characteristics of semi-infinite ground are simulated by using multi-mass point spring and damping system, and the vibration equation of the upper building-foundation-foundation coupling system in the time domain is established. Based on this, the nonlinear and hysteresis characteristics of structural members subjected to strong earthquakes are considered. The seismic response analysis of high-rise buildings is performed over time. The input ground motion intensity, frequency spectrum characteristics, foundation stiffness, and structural member nonlinearity are studied through examples.
