摘要
应用弹簧、阻尼体系模拟半无限地基的动力阻抗特性,建立上部结构-基础-地基耦连体系的运动方程。在此基础上考虑不同地基模型对结构响应的影响,进行了土与结构相互作用线性体系随机地震响应分析,并通过算例分析其影响程度。
A lumped mass-spring-dashpot system is used to simulate the frequency-dependent dynamic impedance of viscoelastic halfspace. The equations of motion for the dynamic analysis of soil-foundation-superstructure system is established. Based on the different viscoelastic foundation models, the stationary stochastic seismic responses of the interaction system of structure and foundation have been calculated.
