| Abstract: | This paper studies the effect of prestressing on the cracking torque and presents a practical equation for predicting the cracking torque of reinforced and prestressed concrete members. The analysis of the author s tests results of 10 prestressed concrete T - beams and the additional 32 test data reported by other investigators at home and abroad shows the author's equation can precisely predict the cracking torque of reinforced and prestressed concrete members. |
