The twisting moments in a spandrel and the bending moments in a slab, butting into it and uniformly loaded, are relaxed by the rotation and the horizontal and vertical displacements of the spandrel, as well as by the rotation of the columns. The influence of these relaxations may be significant and can be assessed by the tables of effective widths, slab bending moments, and spandrel twisting moments given in this paper.

Subject Headings: Moment (mechanics) | Rotation | Slabs | Displacement (mechanics) | Columns | Vertical loads | Bending (structural) | Horizontal loads
