Abstract:
Diagonally reinforced concrete beams coupling reinforced concrete wall piers are a very attractive structural system for resisting lateral loads in medium- to high-rise structures. However, for the design of diagonally reinforced concrete coupling beams (DCBs) to be compliant with ACI 318-05 often necessitates the designer to make inappropriate assumptions or results in unconstructible beam details. A discussion of the design requirements for DCBs is presented along with a number of design examples in an attempt to illustrate the difficulties inherent in designing these elements. Recommendations aimed at simplifying the design of DCBs are presented.
