本期发表的张茂祥同志的“对结构应力分析中的变弹模法的讨论”一文(以下简称“讨论”)提出了许多宝贵的意见。现对原文(指笔者撰写的“结构应力分析中的变弹模法”)说明如下: (一)原文p·3第三行“但biⅠ/和biⅡ可事先任意确定”一语确系原文错误,应为“但biⅠ和biⅡ可事先确定”,其值为biⅠ=μⅠ.bi/μ,和biⅡ=μⅡ.bi/μ,即“讨论”给出的,现证明如下: Comrade Zhang Maoxiang’s “Discussions on Structural Change in Structural Stress Analysis” (hereinafter referred to as “discussion”) put forward many valuable opinions. Now the original text (referred to by the author as “the elastic modulus method in structural stress analysis”) is described as follows: (a) The third line of the original p.3 “But bii/and biII can be arbitrarily determined in advance” is indeed the original error , should be “but biI and biII can be determined in advance”, its value is biI=μI.bi/μ, and biII=μII.bi/μ, that is, “discussion” is given, now proved as follows:
