Flexural behaviour of prestressed concrete pile / Azaha Mohammad

The objective of this study is to investigate the flexural behavior of pre-tensioned prestressed concrete pile. Bending strength test on the pile arc done to determine the cracking bending moment (Me) and the ultimate bending strength (Mu). Three square piles of prestressed of size 125mm x 125mm x 6m were design in accordance with BS 8004:Part 1 : 1974.The bending strength test on pile are made by the application of vertical load P to the centre of the span on the pile laid on two supports which have a span equal to 3/5 of its total length The pile were consider as beam. Cracking load, ultimate load, and deflection were observed and recorded during the testing This experimental result were compared with the theoretical result where it was found out the experimental values are 5.98 kN for cracking load and 7.98 kN for ultimate load. From theoretical results, the value for cracking load is 4.54 kN and for ultimate load is 7.42 kN
