中文摘要：
为有弹性的模量调整的新策略基于忍受比率(EBR ) 的元素被建议，并且有弹性的模量减小方法(EMRM ) 为框架结构的限制负担评估被建议。EBR 被定义采用概括收益标准，并且参考书 EBR 被在结构介绍极值和 EBR 的一致性的度决定。在有比参考书大的 EBR 的元素的有弹性的模量一个人基于线性有弹性的有限元素分析和种类精力的平衡被减少。框架结构的限制负担降低界限被分析，数字例子表明建议方法的灵活性，精确性和效率。
英文摘要：
A new strategy for elastic modulus adjustment is proposed based on the element bearing ratio （EBR）,and the elastic modulus reduction method （EMRM） is proposed for limit load evaluation of frame structures. The EBR is defined employing the generalized yield criterion,and the reference EBR is determined by introducing the extrema and the degree of uniformity of EBR in the structure. The elastic modulus in the element with an EBR greater than the reference one is reduced based on the linear elastic finite element analysis and the equilibrium of strain energy. The lower-bound of limit-loads of frame structures are analyzed and the numerical example demonstrates the flexibility,accuracy and effciency of the proposed method.
