在一般钢结构工程的设计与施工中,往往需要应用角钢重心距离这一杆件截面几何特性参数,作为设计制图和施工放样与号料的依据。对于热轧等边角钢,从YB166-65冶金部部颁标准中,可查得不同规格等边角钢重心距离Z。的给定值。现在提出一个简单的近似计算方法,在工程实践中,省去查找数据的过程,颇为方便。
In the design and construction of general steel structure engineering, it is often necessary to apply the geometrical parameters of the angle of the center of gravity of the bar section as the basis for the design drawing and construction of lofting and numbering materials. For hot-rolled equilateral angle steel, from the YB166-65 Ministerial Standard of the Ministry of Metallurgical Industry, the Z-distance center-of-gravity distance Z of various specifications can be found. The given value. Now a simple approximate calculation method is proposed. In the engineering practice, it is convenient to save the process of searching for data.
