Sažetak
This paper represents a part of diploma work in the scope of glued laminated girders of special geometry. It also shows results of long time research that menthors1, 3 engaged in the field of wooden material, timber structural design and FEM. The main subjects of our interest are Glulam pitched cambered beams. In aesthetic way, a form of these girders is very impressive. Sometimes, however, just an unsuitable form, e.g. inappropriate slope, due to the span and radius of curvature of the apex zone, could provoke very serious problems in practice and jeopardize a safety of the whole structure. Furthermore, as we all know, wood is anisotropic material whose tensile strength perpendicular on fibers is far below the rest of its material properties. For this reason, we must deal very seriously with the safety of the curvature zone of girder, where these stresses appear. In the other hand, EC5 makes some simplifications in design of these girders that are acceptable enough in engineering practice and structural safety. So, we tried to compare the results obtained using rules included in standards (EN, ENV) with those, produced by FE analysis using COSMOS/M program and theoretical model, as well.
