Title:
Abstract:	Im vorliegenden Aufsatz werden Bemessungstafeln zur Vorbemessung von Bauteilen aus Holz - Ermittlung der erforderlichen Querschnittshöhe - in Abhängigkeit definierter Eingangsparameter (Einwirkungen, Geometrie, Systemdefinitionen, Materialeigenschaften) vorgestellt. Eine allgemeingültige Aussage, welcher ULS- bzw. SLS-Nachweis die relevante Bemessungssituation für die Dimensionierung eines Bauteiles widerspiegelt, kann aufgrund der Vielzahl an Einflussparametern, wie z. B. der Materialkennwerte, der Trägerspannweite und der Belastung, a priori nicht eindeutig getätigt werden. Für die effiziente Vorbemessung gemäß ÖNORM EN 1995-1-1 [1] liegen bis dato keinerlei nutzbare Bemessungsdiagramme für biegebeanspruchte Stäbe mit wissenschaftlicher Aussagekraft vor. Design charts for a single spanned timber beam under bending - Part 1: Roof beam with a homogeneous rectangular beam cross-section In the presented paper design charts for the preliminary design of components made of timber (determination of the required cross-sectional height) are shown. The charts are given as functions of several defined input parameters like loads, system geometry and material behavior. A generally valid statement, which kind of verification (ULS or SLS) reflects the relevant design situation for the design of a timber component is not possible. This may occur due to numerous influencing parameters. Currently no design charts for the efficient preliminary design according to ÖNORM EN 1995-1-1 [1] are available.
