Abstract

This numerical analysis study predicts the behavior of spun piles with and withoutconcrete infill under cyclic flexural loading and constant axial load. A fibersection using STKO pre- and post-processor for the OpenSEES program wasemployed. Spun piles were modeled using displacement-based beam-columnelements with distributed plasticity and cyclic loading procedures withdisplacement control. The numerical method proposed for this research wasverified by comparing it to reliable experimental results.

Abstract

This paper describes the results of a study carried out experimentally on the determination of the moment strength ofspun pile piles. The methods used are visual observation, load-displacement curve evaluation, and tensile strain analysis. Theexperimental results show that a load of data taken is delayed between 3 and 9 % compared to the results based on loaddisplacement curve. Analysis results from the load-deflection curve is similar to the tensile strain reading in the PC bar. Atcrack, there exist a sudden jump in the tensile strain of the PC bar where at the same time the stiffness of the load-deflectioncurve was changed.
