【摘要】 为了探索大震情况下岸边集装箱起重机结构的弹塑性分析方法,运用Matlab编程对岸边集装箱起重机进行大震下的弹塑性地震响应分析,通过对比弹性地震响应以说明弹塑性分析的合理性。结果表明,弹塑性分析对研究大型起重设备在地震载荷下的结构响应,以及利用分析结果进行改进设计以提高岸边集装箱起重机结构的抗震能力具有工程实际意义。更多还原

【Abstract】 To study the elastic-plastic method of the quayside container crane under the condition of large vibration,Matlab programming is used to perform elastic-plastic seismic response analysis under large vibration for the quayside container crane,in order to indicate reasonability of the elastic-plastic analysis through comparison with elastic seismic response. The result shows that elastic-plastic analysis indicates actual engineering significance in studying the structural response of large-scale hoisting crane under the seismic load and improving the seismic capacity of the quayside container crane by improving the design based on analysis results.更多还原
