【摘要】:在多尺度計(jì)算方法的基礎(chǔ)上提出了一種精確、高效的結(jié)構(gòu)局部精細(xì)化計(jì)算方法,并采用通用有限元軟件ABAQUS建立一鋼框架的精細(xì)化模型、多尺度模型、基于子結(jié)構(gòu)的多尺度模型和宏觀模型進(jìn)行受力分析。分析結(jié)果表明,基于子結(jié)構(gòu)的多尺度模型能夠達(dá)到與多尺度模型相同的計(jì)算精度,同時(shí)能夠大大提高計(jì)算效率減少計(jì)算時(shí)間,并且計(jì)算容易收斂;谧咏Y(jié)構(gòu)的多尺度模型為復(fù)雜結(jié)構(gòu)關(guān)鍵構(gòu)件的應(yīng)力分析提供了一種新方法。
[Abstract]:On the basis of multi-scale calculation method, an accurate and efficient local fine calculation method of structure is proposed. The fine model and multi-scale model of a steel frame are established by using the general finite element software ABAQUS. The multi-scale model and macro-model based on sub-structure are used to analyze the force. The analysis results show that the multi-scale model based on sub-structure can achieve the same calculation accuracy as the multi-scale model. At the same time, the calculation efficiency can be greatly improved and the computation time can be reduced, and the calculation is easy to converge. The multi-scale model based on substructure provides a new method for stress analysis of key components of complex structures.
