This article describes tests on two full-scale models at the Warsaw Centre for Building Research and Development. The models, built with actual prefabricated units from the factory which produces a system widely used in Poland, represented a three-dimensional console-support effect at a corner after partial damage to a loadbearing gable wall. The aim of the tests was to learn the mechanism of the development of the console support, and to provide quantified data on the interaction of the individual elements composing it, which are here presented in detail. The results indicate that the forces acting in the tie beam and the floor slab, as calculated, are close to actual conditions, and that well-made connections could form a rational solution to preventing collapse of a large-panel structure. Account must be taken, however, of the particular feature of the floor-wall joints and of the possible effect of deplanation of those joints from bending of the floor. Cet article decrit des essais realises sur deux maquettes en vraie grandeur au Centre pour la R & D sur le Batiment de Varsovie. Ces maquettes, construites avec de veritables elements prefabriques provenant de l'usine qui diffuse un systeme tres largement utilise en Pologne, reproduisaient un effet de soutien en console en trois dimensions d'un angle, apres un dommage subi par un mur pignon porteur. Ces essais avaient pour but de comprendre le mecanisme du developpement de ce type de support et de fournir des chiffres sur l'effet reciproque des elements qui le composent et qui sont presentes en detail dans l'article.
