【摘要】 对一般非对称截面梁的弹塑性弯曲变形进行了讨论,并通过分析得到了一近似种求解方法。提出非对称截面梁在荷载作用下其中性轴的位置随梁上作用弯矩的变化是线性变化的,并可通过公式确定,经过验算可知,由此公式求得的结果可满足工程精度要求。更多还原

【Abstract】 The paper studied elastic-plasticity bending deformation of cross-section of unsymmetrical beam and found a solution of deformation.Through research,the article drew a conclusion: the position of neutral axis of unsymmetrical beam linear changed with moment load,and was decided by(the means of geometric senses and physical quantities will be found on chart 1.in the equation).The equation was verified that the results satisfied engineering precision.更多还原
