EFFECT OF SPAN-DEPTH RATIO ON THE ULTIMATE STEEL STRESS IN UNBONDED PRESTRESSED CONCRETE MEMBERS
The effect of member span-depth ratio on the predicted steel stress f sub ps in unbonded prestressed concrete members at their nominal moment resistance is implemented in an approximate manner of ACI 318-83. The recognition of member span-depth ratio and its implementation as an independent design parameter was made based on comparison of limited experimental results. However, there is not yet a clear phenomenological explanation that helps in understanding the mechanism of this parameter and its level of influence on the predicted f sub ps at ultimate flexural strength.
