压型钢板计算问题探讨

Discussion on Calculation of Profiled Steel Sheet

由于《冷弯薄壁型钢结构技术规范》GB50018—2002中对板材材质规定不全、加劲肋形式的认定较模糊、多个中间加劲肋的受压加劲板件未给出计算方法等问题,借鉴对澳大利亚冷弯钢结构标准AS/NZS 4600对这类问题的计算思路和方法,使计算更加详尽、合理,也是对现有规范中计算方法的一个很好的补充。

Because sheet material provisions are not identificated,stiffeners are fuzzy,and a plurality of intermediate stiffener stiffened compression plate piece did not give a calculation method of problems in the cold-formed thin-walled steel structure technical specification GB50018—2002,it is necessary to refer to the calculation methods and ideas of the Australian cold formed steel structure standard AS / NZS 4600,the calculation is more detailed and reasonable,and it is also a good supplement to the calculation method in the existing codes.
