Stirrup sample. Stirrups form the outer part of a rebar cage. The function of stirrups (often referred to as 'reinforcing steel links' and 'shear links') is threefold: to give the main reinforcement bars structure, to maintain a correct level of concrete cover, and to maintain an equal transferance of force throughout the supporting elements.

Tied columns have closed lateral ties spaced approximately uniformly across the column. The spacing of the ties is limited in that they must be close enough to prevent barreling failure between them, and far enough apart that they do not interfere with the setting of the concrete. The ACI codebook puts an upward limit on the spacing between ties.
The lacing elements are typically attached using either hot rivets or threaded locator bolts. As with lattice girders, laced struts and ties have generally been supplanted by hollow box sections, which are more economic to produce with modern technology. In some case seismic retrofit modifications replace riveted lacing with plates bolted in place.
Figure 2 Coupled shear wall acting as a partitioning system Hotel or dormitory buildings require many partitions, allowing insertions of shear walls. In these structures, traditional cellular construction (Figure 2) is preferred and a regular wall arrangement with transverse cross walls between rooms and longitudinal spine walls flanking a ...
