Abstract |
The dual potential capacity model (DPCM) was extended to be suitable for evaluation of the shear strength of prestressed concrete (PSC) members in the previous study. This paper aims to simplify the DPCM for its better application in practice. To this end, a total of 172 shear test results of PSC members without shear reinforcement were collected from existing studies. The collected shear test results include PSC members with various section types and prestressing methods. It appeared that the simplified model could provide a good level of estimation accuracy of shear strength of PSC members, and it was comparable with that provided from the original DPCM.
