英文摘要	A two-layer frame structure was selected, and multi-scale finite element models were established by the constraint equation method and the sub-model method respectively, in order to study the multi-scale finite element modeling technology of steel structures under wind and to verify its rationality. Wind load static analysis, dynamic time history analysis and wind-induced fatigue analysis were performed; the obtained results were compared with those of single-scale models; the characteristics of those multi-scale finite element model were studied. Based on these, the selection of local micro scale model size was studied. Results show that in static analysis, dynamic time history analysis and fatigue analysis, the results of multi-scale models are in good agreement with those of single-scale models and the accuracy can meet the engineering demand. The sub-model method is more accurate than the constraint equation method, but is more sensitive to the local model size. For those steel frame structures with similar beam and column size to this structure, the distance between the boundary and the horizontal axis of the research location is recommended to be 0.05 m when the constraint equation method is used, while to be 0.1 m when the sub-model method is used. © 2018, Zhejiang University Press.
