The interior arrangement of wall columns, horizontal beams and cornice bracketing corresponds with that on the outside.
SPANDRIL, or Spandrel (formerly splaundrel, a word of unknown origin), in architecture, the space between any arch or curved brace and the level label, beams, &c., over the same.
The structures in which steel concrete is used may be analysed as consisting essentially of (I) walls, (2) columns, (3) piles, (4) beams, (5) slabs, (6) arches.
Concrete by itself, though strong in compression, can offer but little resistance to tensile and shearing stresses, and as these stresses always occur in beams the problem arises how best to arrange the steel so as to assist the concrete in bearing them.
Floor slabs may be regarded as wide and shallow beams, and the remarks made about the stresses in the one apply to the other also; accordingly, the various devices which are used for strengthening beams recur in the slabs.
