EFFECTS OF SLOPE AND APEX ZONE GEOMETRY OF GLULAM BEAMS WITH SPECIAL SHAPE ON THEIR DESIGN
This paper represents a part of diploma work in the scope of glued laminated beams of special geometry. The main subjects of research we have made are glulam pitched cambered beams and curved beams. An unsuitable form, e.g. inappropriate slope and shape of apex zone, due to the span and radius of curvature of the curved zone, could provoke very serious problems in practice and jeopardize a safety of the whole structure. Wood is anisotropic material whose tensile strength perpendicular on fibres is far below the rest of its material properties and we must deal very seriously with the safety of the curvature zone of girder, where these stresses appear with their maximum values. Codes make some simplifications in limit states design of these girders. These simplifications are acceptable enough in engineering practice, but we tried to compare results obtained by rules included in EN 1995-1-1 and DIN 1052, linear static FE analysis and theoretical models. We also presented some practical advises for their design and practical application.
