Abstract

This paper presents an innovative seismic isolation system for the structure and unbounded rubber soil. The dynamic interaction of the rubber soil and structure is considered. The rubber soil mixture is constituted by rubber particles and clay. The pollution problem of wast rubber is solved effectively. The rubber soil is firstly introduced into the ordinary unbounded foundation. According to the composite material theory and hybrid law, the rubber soil modulus formulation is derived by two-phase modulus innovatively. By employing the standard viscous boundary method, the radiation damping of unbounded rubber soil is considered. And then, the novel wave propagation equation of unbounded rubber soil is derived. Based on the cylindrical expansion wave and cut-off wave assumptions, the normal and tangential boundary condition equations are derived, respectively. The interaction force causing by earthquake on the rubber soil and structure is modeled. Numerical examples are presented to demonstrate the effectiveness and reliability of the proposed method for the rubber soil and structure interaction model. The seismic response of the rubber soil and structure system is discussed. Excellent seismic performance of rubber soil is confirmed. The influence of the rubber soil content and thickness are discussed in detail.

橡胶地基与结构动态相互作用的数值研究

本文介绍了一种创新的结构和无约束橡胶土壤隔震系统。考虑了橡胶土壤和结构的动态相互作用。橡胶土壤混合物由橡胶颗粒和粘土构成。有效解决了废橡胶的污染问题。首先在普通无界地基中引入橡胶土。根据复合材料理论和混合定律，创新性地推导出橡胶土壤两相模量公式。通过采用标准粘性边界法，考虑了无界橡胶土的辐射阻尼。然后，推导出无界橡胶土的新型波传播方程。基于圆柱膨胀波和截止波假设，分别导出了法向和切向边界条件方程。模拟了地震对橡胶土壤和结构造成的相互作用力。通过数值实例证明了所提方法在橡胶土壤与结构相互作用模型中的有效性和可靠性。讨论了橡胶土壤和结构系统的地震响应。证实了橡胶土壤优异的抗震性能。详细讨论了橡胶土壤含量和厚度的影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
