Changes in the Oscillation Mode Shapes and Natural Oscillations of the Steel Beams Depending on the Beam Web Rigidity

Abstract

The object of study is the steel span structures of conveyor galleries which is a widely used beam system span. Technological loads acting on the building construction conveyor galleries are dynamic in nature due to the force. This article presents the results of numerical simulation of dynamic behavior of welded metal beams in conveyor galleries. Investigations were carried out for the beams having symmetrical cross-sections and evenly-spaced transversal ribs with various spacing between the ribs in different beams. The regularities of changes in the oscillation mode shapes depending on the beam geometric characteristics have been investigated.
