轻型钢结构吊车梁优化设计

Optimization Design of Crane Girder in Portal Frame Buildings

通过分析和研究单层门式刚架轻型钢结构厂房中的吊车梁设计 ,总结了轻型钢结构吊车梁的优化设计方法和节点连接构造 ,对合理设计吊车梁 ,降低用钢量提出了设计建议。

This paper investigates the design method of crane girders applied in portal frame buildings.An optimal design approach was proposed to reduce the grider weight and fabricate the crane girder economically.Finally some design examples were given to illustrate the efficiency of the proposed method.
