[摘要]在考虑剪力影响的基础上,推导了工字型钢梁的弯曲正应力公式,讨论了工字型钢梁截面跨高比变化时剪力对其弯曲正应力的影响。研究结果表明:随着跨高比的增大,剪力对弯曲正应力的影响逐渐减小;且剪力对工字型钢梁腹板最大弯曲正应力的影响较大。

[关键词]剪力; 工字型钢梁; 弯曲正应力; 跨高比

Abstract:On the basis of considering the effect of shear force, the formula of bending normal stress of I-type steel beam was deduced, and the effect of shear force on bending normal stress of I-type steel beam when the span-height ratio of cross-section changes was discussed. The results show that with the increase of span-height ratio, the effect of shear force on the bending normal stress decreases gradually, and the effect of shear force on the maximum bending normal stress of I-type steel beam web plates is greater.

Keywords:shear force; I-type steel beam; bending normal stress; span-height ratio
