摘要:This paper presents a kinematic model for deep beams capable of describing the deformed shape of such members in terms of just two primary parameters. The kinematic model is combined with equilibrium equations and stress-strain relationships to form a theory to predict the shear ...

摘要:An experimental study on eight large reinforced concrete deep beams was performed. The variables were the shear span-depth ratio (a/d = 1.55 or 2.29), quantity of stirrups (0.0 or 0.1%), and type of loading (monotonic or fully reversed cyclic). All members failed in shear be...

摘要:This paper presents a theory for predicting shear strengths, deformations, and crack widths near failure of continuous deepbeams. To describe the deformations in continuous deep beams, the theory uses a three-degree-of-freedom kinematic model (3PKT), which is an extension of an e...

摘要:While different design codes provide similar guidance for the flexural design of prestressed thin-webbed continuous girders, the shear design provisions differ greatly. This paper investigates these discrepancies with the help of 11 experiments and a number of analytical studies....

摘要:While anchor heads are particularly useful in the case of large bars, which require significant development lengths, the ACI Code provides design guidance for bars No. 11 or smaller. This paper presents a test of a large deep beam reinforced with a single No. 18 headed bar. The b...
