轨道式集装箱门式起重机地震响应分析
|
摘要
地震是一种破坏性极大的自然灾害,会对人类生命和财产安全造成巨大威胁。因此,结构的抗震研究是工程领域的重要研究内容。以轨道式集装箱门式起重机为研究对象,采用动力时程分析法对起重机进行地震响应分析,获得危险截面处地震响应曲线。分析结果表明:该机能够抵御7度罕遇地震的作用。
Earthquake is a destructive natural hazard, causing enormous threat to safety of human life and property. Therefore,anti-seismic study on the structure is an important task in the engineering field. With the rail-mounted container gantry crane as the study object,the earthquake response analysis is performed for the crane with the dynamic time-procedure analysis method,in order to get the earthquake response curve at hazardous cross-section. The analysis result shows that the crane is able to withstand Degree-7 rarely-occurring earthquake.
