中欧规范关于双向偏心受压构件计算方法的对比

Comparison of Calculation Methods for Biaxial Eccentric Compression Members between Central and European Codes

我国规范与欧洲规范针对双向偏心受力构件的计算要求,在计算方法上有较大不同,由此对计算结果也产生影响。故详细介绍了我国规范GB50007[1]与欧洲规范EN1992[2]有关理论背景,对影响双向偏心受力构件计算结果的因素进行了对比分析,并结合算例对两种规范的配筋计算结果进行了详细对比。分析结果表明,中欧规范在屈服理论,验算方法等方面的规定存在一定差异,反映出中欧规范在双向偏心受力构件影响因素方面存在不同考虑及机理认识上的差异,这些差异使由此计算所得到的构件配筋设计有所不同,欧洲规范方法更为保守。

China standard and European standard for the calculation of biaxial stress components, are quite different in the calculation method, which had effect on the results.This paper describes the Chinese standard GBS0007[~land European standard EN199212]related theorefical background, t~ the influ^nce ~f d^ub^e ~ccentri~ f^rce mak^s a c^ntrastive analysis ~f c^mp^n~nt fact^rs ~f the calculated results, combined with the examples of two types of reinforcement calculation results are compared in detail.The analysis results show that the EU norms in the yield theory, there are some differences between the provisions of the calculation methods, reflect the EU norms in the biaxial eccentric force component factors there are different considerations in the aspect of the element and the difference of mechanism cognition. These differences make the design of the component reinforcement different from the Calculation; and the European standard method is more conservative.
