A STATISTICAL APPROACH TO COMPOSITE BEAMS
Composite beams demonstrate many features which make a probabilistic approach very desirable, e.g. a considerable variation within such material properties as strength and modulus of elasticity. Moreover, a strong correlation between stiffness and strength properties can exist. The effect on the failure risk of this correlation is of great interest. In this paper the beam-action is treated for the special case o a rigid joint behaviour. The mechanical properties for this case are described. Simplified design methods presented by Cornell and Hasofer-Lind are used for the statistical analysis. These methods are briefly described. The described failure modes are treated from a statistical point of view with special regard to correlation between influential parameters. The difference in calculated formal failure risks for the different statistical methods used is demonstrated. In some special cases, we consider the complete beam structure when all the failure modes may occur. (Author)
