Bemessungsdiagramme für den biegebeanspruchten Stab im Holzbau - Teil 2: Deckentragwerke mit inhomogenem Stabquerschnitt

Design charts for a single spanned timber beam under bending - Part 2: Floor structures with inhomogeneous beam cross-section

This paper presents an application of design charts for inhomogeneous cross-sections (layered composite section) and the implementation of vibration design criteria as extension of the charts for beams with homogeneous cross-sections in roof-structures according to selected European Design Standards published in [1]. While ULS and SLS criteria were nearly equally governing for the homogeneous cross-section, mainly SLS criteria are now governing due to the extension with vibrations and the influences of the inhomogeneous cross-sections. The vibrational behavior of floors is essentially influenced by the support conditions. Effects of moment restraints at the wall-floor-wall detail, activated by wall-loads from stories above, are systematically being taken into account.
