Imperfection Sensitive Buckling of Rectangular Frames with Elastic Bracing Stiffness
Original language description
The effect of initial random imperfections on the random load carrying capacity of rectangular frame is studied. The load carrying capacity is calculated by means of geometrically nonlinear FEM solution. The height of the columns and bracing elastic stiffness are non-random parameters, taking into consideration the condition that the non-dimensional slenderness of columns is constant. Design load carrying capacity is calculated acc. to EN1990 as 0.1 percentile. Results show that the safety of design according to EUROCODE 3 is misaligned. The Sobol variance based sensitivity analysis of random load carrying capacity is used to identify the dominant input random imperfections and their higher order interaction effects.
