Abstract
A scaffold coupler may be regarded as a short rigid member having multiple elastic connections at both or at one of its ends. The elastic properties need to be determined experimentally; suitable tests are described. Results are used for establishing matrices for unsymmetrical and symmetrical right angle couplers and for symmetrical swivel couplers. An example is given of the use of scaffold coupler matrices in calculations for the elastic instability strength of a three-storey scaffold tower.
Résumé
Un raccord d'échaffaudage peut être considéré comme un court membre rigide possédant des connexions élastiques multiples à l'une ou à chacune de ses extrémités. Les propriétés élastiques demandent a être déterminées expérimentalement et on décrit des essais appropriés. On s'est servi des résultats pour établir des matrices pour des raccords orthogonaux symétriques et asymétriques, ainsi que des raccords articulés symétriques. On donne un exemple de l'utilisation de ces matrices pour le calcul de la résistance d'un échaffaudage-tour à trois étages.
