摘要
根据新规程,檩条的用钢量由于活荷载取值的变化而发生了变化。本文结合《门式刚架轻型房屋结构技术规程》(CECS102:2002),《冷弯薄壁型钢技术规范》(GB50018-2002),用遗传算法对常见荷载和柱距条件下檩条的截面进行了优化设计,并根据新规程对檩条的用钢量进行了比较分析。其结论有较好的应用价值。
According to new standard, the consumption of steel of purlin in engineering changes with the variation of loading. In the paper, based on The Codes Of Technique Of Door- type Steel Support Structure For Light Houses and The Standard Of Technique Of Cold- formed Thin- wall Bar Structure （GB50018 - 2002）, genetic algorithm is used to make optimization design of size of section of the purlin under the general conditions of loading and distance between poles. The consumption of steel of new stand and traditional standard are analysed and compared. The result of paper has good value of application.
