【摘要】 考虑钢板仓和地基的相互作用和地震时土的非线性,采用有限元程序MARC提供的动力时程分析法,添加邓肯-张非线性地基本构模型,针对不同设防烈度的场地,应用三种典型的地震波形对一个利浦式地基-钢板仓结构模型进行非线性时程响应分析。结果较符合实际,能够描述钢板筒仓的运动特征,并从中发现了一些特点和规律,分析结果可为钢板仓结构工程抗震分析和安全设计提供参考。更多还原

【Abstract】 The nonlinear finite-element method is used to analyze the nonlinear temporal dynamic response of a lipp steel silo structure by considering the nonlinear characters of soil and the interaction between the foundation and the silo under seismic loads with adding Duncan-zhang model to Marc.The computed results are accordant with the practice.Some characters and regulations are found and can be used to describe dynamic characters of steel silo.These results become the basis for the dynamic stress analysis and the security evaluation of steel silo.更多还原
