Imperfections in Steel Plated Structures - Should we Straighten their Plate Elements?

Popis výsledku v původním jazyce

As a result of their fabrication, in particular of the welding involved, steel plated structures exhibit initial imperfections, the most important of them being probably the initial curvature of the plate elements of the system. With this being so, it isunderstandable, that they be kept under control by means of prescribed tolerances, and there is a tendency to reduce the initial curvatures by means of (usually heat) straightening. But this procedure is costly and necessarily enlarges the price of thefabrication of the structure. Is it therefore indispensable to proceed in this way? And is this so for all kinds of steel plated structures? Parallelly with experiments, the ultimate load tests were computer modelled. In so doing, the girder was modelled, using the geometrically and materially non-linear variant of the shell finite element method, by the ANSYS program. Considering a random influence of all initial imperfections, a case study analysis of the effect of all imperfections on
