Kajian metode penentuan kekuatan momen retak tiang pancang spun pile

Abstract

This paper describes the results of a study carried out experimentally on the determination of the moment strength of
spun pile piles. The methods used are visual observation, load-displacement curve evaluation, and tensile strain analysis. The
experimental 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. At
crack, there exist a sudden jump in the tensile strain of the PC bar where at the same time the stiffness of the load-deflection
curve was changed.
