Calculation of an ultimate load value of a silo with geometric imperfections in the shape of eigenforms
Abstract
The ultimate load value of a silo with initial geometric imperfections was measured. The structure was loaded with wind. Imperfections were assumed as translations of the shell nodes from perfect geometry taken from eigenforms and their combinations. Two variants of the maximum deflection placement with respect to the direction of wind pressure were proposed. The first consists in applying the maximum wind pressure to the element of maximum displacement outwards the silo shell, the second – inwards the shell. A comparative analysis of critical wind pressure values was conducted – between imperfect and perfect silo cases and between the silos with imperfections assumed as eigenmodes and as random fields.
