不等柱距厂房的改造验算及技术处理

CHECKOUT AND TECHNIQUE MEASURE OF MILL BUILDING WITH UNEQUAL COLUMN SPACING

针对某轧钢厂的改造要求 ,对原厂房进行了全面验算。通过增大吊车之间最小间距 ,使原吊车梁满足新荷载的要求。还提出了柱距不相等厂房的计算单元选取方法 ,并给出了有别于现有文献的荷载分配方式。该分配方式力学概念清楚 。

A overall checkout has been carried out for the original mill building in accordance with the requirements of reforming a steel rolling mill Moreover,a technical measure has been adopted to make the crane girder carry the new load by adding the minimum distance of the cranes A method of selecting calculated unit and sharing load for the unequal column spacing of the mill building is also put forward in this paper The load sharing method is clear,simple and convenient
