Geometrically Non-linear Finite Element Reliability Analysis of Steel Plane Frames With Initial Imperfections

Popis výsledku v původním jazyce

The random load carrying capacity of steel plane frames with bracing stiffness is studied in the presented article. The load carrying capacity is evaluated using the geometrically non-linear FEM analysis. The incremental stiffness matrix of a slightly curved element utilized in the non-linear incremental analysis is listed. Initial imperfections are considered as random variables. Statistical analysis and Sobols sensitivity analysis are performed using the Latin Hypercube Sampling method. The effect ofinitial random imperfections on the load carrying capacity is studied, whilst assuming constant non-dimensional slenderness of the columns. The evaluation parameter is the pair of non-random values of elastic bracing stiffness and system length of the columns. The paper illustrates that the load carrying capacity is very sensitive to the initial crookedness (bow imperfections) of the columns in the event that the non-sway (symmetric) and sway (anti-symmetric) buckling modes coincide.
