Abstract: This paper describes an investigation into the redistribution of moments in certain composite concrete beams. Seven two-span beams 6.2 m long were constructed and tested by means of applying two point loads at midspans. ...

Abstract: This article presents an investigation of redistribution of moments in normal-strength concrete (NSC) and high-strength concrete (HSC) continuous beams. A nonlinear computer model is introduced and validated by experimental ...

Abstract: For external tendon members subjected to sustained loads, the time-dependent effects resulting from concrete creep, shrinkage, and tendon relaxation would interact with the second-order effects resulting from the change ...

Abstract: This article presents the results of a numerical investigation of the flexural behavior of continuous externally prestressed concrete beams. Aspects of behavior studied include the increase in stress in external tendons, ...
