Abstract:
Two existing theories for shear design of RC panel structures were investigated. It was found that the first theory to obtain the crack angle included a theoretical mistreatment and in the second (Modified Compression Field Theory), the strain compatibility is equivalent to the assumption of no shear slips across crack interfaces. The first finding indicated that the crack angle cannot be used as an independent variable to determine uniquely the state of stresses, strains, and crack configuration. However, the strain compatibility can be used instead. Also, it was noted that aggregate interlock and dowel action have small effect on the shear resistance of RC panels.
