| 摘 要： | 采用能量法对多自由度剪切型结构隔震体系进行非线性地震反应分析时,其计算量大、分析复杂,难以用于工程实际.针对上述问题,将对其多自由度振动方程进行求解分析,找到一种等代体系来简化隔震体系的求解过程,并简要分析了近断层地震动三要素对滑移隔振结构总输入能的影响.最后,对一五层框架隔震结构模型分别采用能量分析法和简化后的能量法进行计算,将其结果进行对比,说明了本文提出的计算方法是偏于安全的,为工程的抗震设计提供参考. |

| Abstract: | A large amount of calculation and complex analysis is involved in the nonlinear seismic response analysis of the multi-DOF shear structure isolation system with the energy method,not ready for use in engineering practice.In order to solve these problems,this paper,through its analysis of free vibration equation,finds an equivalent system to simplify the solution of the isolation system.And the influence of three elements of near-fault ground motion on the total input energy was simply analyzed.Finally,a five-storey framework isolation structure model under the action of earthquake is respectively analyzed by energy method and the simplified calculation method Compared with the results,it shows the method proposed is rather safe,which also provides the reference for the seismic design of the project. |
