Structural Design of Special Steel Industrial Workshop Office Building

特钢工业厂房办公楼由2栋长90.6 m、宽34.2 m、高36.5 m的塔楼组成,两个塔楼之间2层设置钢平台,一端铰接,一端滑移。通过方案比选,两塔楼均采用钢框架(局部设支撑)结构体系,标准轴网为8.4 m×9.0 m,结构布置基本对称,相邻处端部一跨存在斜柱。针对斜柱对结构的不利影响,对结构进行了pushover分析,并采取了相应的措施;2层的钢平台跨度较大,进而做了舒适度分析,结果表明,满足规范的要求。

The office building of special steel industrial plant is composed of two towers with a length of 90.6 m,a width of 34.2 m and a height of 36.5 m.A steel platform is set on the second floor between the two towers,with one end hinged and the other sliding.Through the scheme comparison,the two towers adopt steel frame structure system(with local support),the standard axis network is 8.4 m×9.0 m,the structure layout is basically symmetrical,and there are inclined columns at the end of the adjacent span.In view of the adverse effect of inclined column on the structure,pushover analysis is carried out on the structure,and corresponding measures are taken;the span of the second floor steel platform is large,and then comfort analysis is carried out,and the results show that it meets the requirements of the specification.
