摘　　要：本文对塔式起重机塔身标准节进行了简化,分别在三种工况下进行了内力分析,通过对四种单元的计算结果与试验结果的比较,得出beam189单元计算精度最高,beam4单元在相同的网格情况下精度略低但其计算时间较短。同时对原标准节模型进行了参数优化,并将优化结果根据规范的要求进行了调整,以便能够满足工程实际的要求。By simplifying the tower crane standard section, calculating internal force under three loading conditions and comparing results of four elements with experimental data, in the four elements beam189 element has the highest precision and that beam4 element has moderate precision and computing time. The parameters of the original standard section was optimized. The optimization results were adjusted by codes requirements so that they can meet requirements of engineering practice. The method of study may be useful as a reference for mechanical designers.
