摘要
Lateral torsional stability of timber beams with monosymmetric cross-sections. Proposals based on large parametrical studies (Balaz 1999a, Balaz & Kolekova 1999a, Kolekova 1999a, b) given in (Balaz & Kolekova 2000a, b, 2002a, b) for calculation of elastic critical moment M-cr of beams under different loadings and various boundary conditions were accepted by prEN 1999-1-1: May 2004 and EN 1999-1-1: May 2007 for design of aluminium structures. They are used also for design of steel structures. This procedure may be used for design of timber structures too. Comparison and evaluation of different procedures for critical moments M-cr calculation for timber beams. Examples show advantages of authors procedure which is already used for design of metal structures. Use of Bessel functions for critical moments M-cr calculation.
