Deformation of partially prestressed concrete beams under service loads.
Nine tests were carried out on partially prestressed concrete beams in which 50 percent of the service load was sustained for a period of up to 46 days during which time the load was increased to the full service load up to seven times in intermittent short-term cycles. One cycle of short-term …

Shear Behavior of Reinforced Concrete Beams and Prestressed Concrete Beams
… the last decades, developments in high-strength concrete materials are rapid, but codes of practice still limits the concrete compressive strength in design of concrete structures due to a lack of experimental research data. As an effort to overcome the limitation to the use of high strength …

Top Strand Effect and Evaluation of Effective Prestress in Prestressed Concrete Beams
… orientation on bond strength in pretensioned prestressed concrete members. The "top strand effect" was evaluated through transfer and development length tests of prestressed concrete beams. Eight beams were cast with normal orientation, while four beams were cast with inverted orientation so …

A new ultimate limit state approach to the design of prestressed concrete beams
The present approach to the design of prestressed beams is antiquated and time consuming. Neither SLS or ULS requirements are satisfied directly. There is a need for a new approach using plastic principles to design the prestressing requirements at ULS considering a whole span at a time, with …

A study of the deflection and strength of partially prestressed concrete beams with unbonded tendons
Fifteen beams with-unbonded tendons consisting of I and rectangular sections with different amounts of prestressed and non-prestressed reinforcement, were tested under short-term and sustained loading and a combination of sustained loading with intermittent short-term cyclic loading(combined …
