An elastomeric seal for connecting two relatively movable architectural structures, such as floor sections, is constructed to optimize resistance to failure of the elastomeric element, in either adhesion or cohesion modes. An elastomeric seal, and an underlying support plate are provided with gently undulating, somewhat sinusoidal surface configuration, with the elastomeric element being of downwardly convex configuration and of relatively maximum thickness in its center, and of downwardly concave configuration and relatively less thickness in regions spaced on either side of center. Widthwise stretching of the elastomeric element tends to be concentrated in the regions of downwardly concave configuration, being thus not only distributed but also located away from areas of maximum vertical stress. An underlying supporting plate is provided with relatively thin, deformable edge flanges, which enable the supporting plate to function as a mold bottom, for pouring of a curable liquid elastomer at a nominal width, while at the same time allowing lateral compression of the assembly to a lesser width during normal functioning of the sealing system.
