本文研究钢板梁剪切承载力问题的特点和国内外的研究现状及存在问题。提供了用ADINA模拟工字梁,由加载至丧失承载力全过程的非线性有限元计算模式和具体做法。该法已用于50多根工字梁的计算,较好地反映了翼缘、横肋等各种因素对剪切承载力的影响。计算结果与试验值能很好吻合。该法为比较、修正国内外现有计算公式,在我国的设计规范中引入这一内容打下了基础。
In this paper, the characteristics of shear bearing capacity of steel beam and the research status and existing problems at home and abroad are studied. This paper presents a non-linear finite element calculation model and concrete method of simulating I-beam with ADINA from loading to losing the whole bearing capacity. The method has been applied to the calculation of more than 50 I-beams, which better reflects the influence of various factors such as flange, transverse ribs on the shear bearing capacity. The calculated results are in good agreement with the experimental values. The law for the comparison, amendment of the existing formula at home and abroad, in the design of our country to introduce this content laid the foundation.
