土木工程学报1962年第2期中,林宣中同志在苏联倪克勤建议的斜偏心受压钢筋混凝土构件计算公式的基础上,应用微分导出了矩形对称配筋截面经济钢筋量的关系式,并编制了计算表格,使计算更为简捷。这一工作是有一定意义的。为了进一步了解该文中公式的推导和表格数值的适用性,我们对几种不同的斜偏心受压情况进行了计算和分析,对原文提出几点意见与原文作者商榷。 (一)原文称欲使钢筋面积设计得最小,必须
In the second part of the Civil Engineering Journal, 1962, Comrade Lin Xuanzhong, on the basis of the calculation formula of the oblique eccentric compression concrete member proposed by Ni Keqin of the Soviet Union, applied the differential to derive the relation formula of the economical reinforcement quantity of the rectangular symmetrical reinforcement and calculated the formula. Forms make calculations simpler. This work is of some significance. In order to further understand the derivation of the formula and the applicability of the table values, we have calculated and analyzed several different oblique eccentric compression conditions, and proposed some opinions on the original text to discuss with the original author. (a) The original said that it is necessary to minimize the design of the rebar area.
