摘要:
为了深入地认识和理解无明显屈服特征构件的屈服点确定方法,首先,揭示了已有的屈服点确定方法的基本原理;其次,对等能量法、最远点法和双直线能量等效面积法的计算方法和计算步骤进行了简化和改进;再次,比较不同屈服点确定方法之间的关系和计算结果,对计算结果存在的差异进行了理论分析;最后,通过实例验证了理论分析的正确性,并对不同屈服点确定方法进行了分析和评价。通过理论分析和实例验证,得出结论:屈服位移由大小依次为等能量法、最远点法和双直线能量等效面积法;计算工作量由大到小依次为双直线能量等效面积法、最远点法、等能量法。
Abstract:
It is significant to derive the yield point of structural components without obvious yield features in order to evaluate the ductility and energy dissipation capacity of these structures. However, there is no unified and definite expression of yield point determination methods for structural components without obvious yield features. For above problems, firstly, the existing methods employed to determine the yield point were summarized and the basic principles of these methods were revealed. Secondly, calculation method and calculation procedure were simplified and improved. Thirdly, theoretical analysis of relationship and reasons of different calculation results among above methods were carried out. Finally, the correctness of theoretical analysis results was verified by an example. The conclusion is obtained that the yield displacement calculated by above three methods from the size followed by equal energy method, the furthest point method, and bilinear energy equivalent area method; the amount of the calculation work from the size followed by bilinear energy equivalent area method, the furthest point method, and the equal energy method.
