STUDY OF THE PARTICIPANT WIDTH IN STRUCTURES COMPRISING ISOTROPIC AND ORTHOTROPIC SLABS

ETUDE DE LA LONGUEUR PARTICIPANTE DANS LES STRUCTURES A DALLES ISOTROPE ET ORTHOTROPE

The authors recall that the problem of the participant width of a beam is complex. It depends on several factors: abscissa of the section, geometric characteristics of the beam, degree of orthotropy of the compression table and especially the loading technique. Attention is drawn to the influence of the orthotropy of the compression table: it improves the utilization of the materials by increasing the participant width of the beam. This increase is of the order of 12% in the case of the model studied. In practice, calculations must be simple and reliable, thus necessitating a uniform participant width along the beam. The well-known formula whereby the participant width is equal to the third of the distance between the points of zero moment, is very satisfactory in the case of distributed loading. In the case of concentrated loading, the participant width must be reduced as a result of the narrowing occurring in the vicinity of the load. /TRRL/
