Nonlinear and linear analysis of the overall stability of the load-bearing system of a high-rise building with a load-bearing trunk

The results of numerical calculations can and should be verified, but testing a complex detailed computational model is problematic. This possibility provided by simplified models represented simple schemes that are available for qualitative analysis, the obtained predictable. Such calculation schemes, as rule, describe individual tasks facing designers. For example, linear stability analysis offered American Institute Steel Structures (AISC). One these discussed. under consideration based on cantilever rack, which considered bearing trunk high-rise building. A comparison critical loads nonlinear rack carried out. It concluded makes it possible to obtain preliminary estimate load verify computer using more general equilibrium high-altitude object.
