| 摘 要： | 在钢结构受弯构件设计中，构件塑性性能的不适度利用很容易导致过度变形，这是一个很值得重视的问题，文中针对钢结构常用的工型截面梁进行了分析，从理论上阐明了这一问题，并通过计算数据验证了所提出的观点，最后，给出了解决这一问题的几种方法及建议。

| Abstract: | While a design for flexural members in steel structure is in progress,the over use of the plastic behavior of the steel member may cause the problem of over deformation,which is a problem deserve regard.By the analysis of the beam with usual I shaped section,the real cause of the problem is revealed,further more,data validate the view which is proposed in this paper.And several measures for the settlement of this problem are given at last. |
