Abstract:
Structural behavior of inverted T-beams diffem from thaf of the more conventional top-loaded standard T-section. The response of prestressed members may be significantly different from that of reinforced members. Due to the iack of recommendation available for the design of beams to resist torsion, this study was conducted to provide data for designing both conventional and prestressed concrete inverted T-beam bentcaps with special attention to web reinforcement, both the amount and location of stirrups; service load cracking in response to equal and opposite torsions due to traffic toads; strength and stiffness of web and flange as the amount of combined texure, shear, and torsion increases to the maximum capacity. Strength and serviceability behavior of inverted T-beams bentcaps is also examined with emphasis on experimental study.
