1977年11月,英国标准协会技术委员会13/20颁发了《英国房屋钢结构规范》(草案)(征求意见稿)(以下简称“英规(草)”)。“英规(草)”与该规范的1969年版(BS449:第二部分)相比,变化较大。它吸收了近一二十年来英国和其它一些国家钢结构的研究成果,也保持了英国规范的传统形式。本文对“英规(草)”不作全面的介绍,主要就其基本计算方法和稳定计算问题介绍一些情况。
In November 1977, the British Standards Association Technical Committee 13/20 issued the “Britain House Steel Structural Code” (Draft) (Draft for Comment) (hereinafter referred to as “British Regulations (Grass)”). “British regulations (grass)” compared with the 1969 version of the specification (BS449: Part 2) has changed considerably. It absorbed the research results of steel structures in the United Kingdom and other countries in the past decade or two and also maintained the traditional form of British norms. This article does not give a comprehensive introduction to the “British Regulations (Grass)” and mainly introduces some basic calculation methods and stability calculation issues.
