［摘要］考慮鋼板倉和地基的相互作用和地震時(shí)土的非線性，采用有限元程序MARC提供的動(dòng)力時(shí)程分析法，添加鄧肯-張非線性地基本構(gòu)模型，針對(duì)不同設(shè)防烈度的場地，應(yīng)用三種典型的地震波形對(duì)一個(gè)利浦式地基-鋼板倉結(jié)構(gòu)模型進(jìn)行非線性時(shí)程響應(yīng)分析。結(jié)果較符合實(shí)際，能夠描述鋼板筒倉的運(yùn)動(dòng)特征，并從中發(fā)現(xiàn)了一些特點(diǎn)和規(guī)律，分析結(jié)果可為鋼板倉結(jié)構(gòu)工程抗震分析和安全設(shè)計(jì)提供參考。

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.

Keywords:steel silo; interaction; finite element; nonlinear; seismic loading; dynamic response
