Analysis of the influence of geometrical imperfections on the equivalent load stabilizing roof truss with lateral bracing system
The paper is focused on the numerical analysis of the stability and load bearing capacity of a flat steel truss. The structure is supported by elastic lateral braces. The translational and rotational brace stiffness are taken into account. The linear buckling analysis is performed for the beam and shell model of the truss. The nonlinear static analysis is conducted for the structure initial geometric imperfections. As a result, the buckling and limit load depending on brace stiffness has been obtained. The reactions in elastic braces are compared to stabilizing forces calculated on the basis of actual code requirements
