Estimation of stress-strain state of metal structures in erecting process has always interested specialists both during design and construction. When using different erection technologies of metal structures a lot of states of building frameworks occur, which are characterized by various, constantly changing analytical models. Computer analysis of force elimination of construction errors was performed for a double-layer framed dome with meridional ribs and horizontal rings with different assembly analytical models. Several types of assembly analytical models of double meridional ribs were considered for erection process of the dome framework with temporary central support. For every model point loads were applied to selected nodes to eliminate relative deflection of adjacent ribs, and initial internal forces appearing in the bars were computed. The results of the analysis are presented in the form of diagrams, models, mosaic of forces in the bars, and figures of joints. Based on the analysis, conclusions are made about favorable assembly models for the erection process of the dome framework.
