Abstract:
Traces the development of code provisions for transfer of unbalanced moments. Flexible provisions of earlier codes now are found to be rigid in assigning the portions of the unbalanced moments to be transferred by flexure and eccentricity of shear. Flexibility in application, which is absolutely necessary in the design of three-dimensional structures with multiple column-to-slab connections, is not available to the designer. A review of available research indicates that a simplified design approach that allows the designer flexibility to develop connections without the need to revise sizes is possible and safe. Thus, alternate code provisions are urgently needed.
