<p>In the present study, a series of laboratory experimental model tests and three-dimensional finite element model tests on laterally loaded barrette have been conducted in granular soil media to examine the behaviour of bending moment and lateral load carrying capacity of the barrette. The length and flexural rigidity of the barrette have been kept constant while the relative density of the granular media and the aspect ratio of the barrette have been varied. The results recorded from the experimental studies have been compared with the developed numerical model. The increment of the relative densities of the sand and aspect ratio of the barrette influence the behaviour of design parameters (i.e., bending moment and lateral load carrying capacity) of barrette. The present study infers that the ultimate load-carrying capacity of barrette significantly increases with the increment of relative density of sand and aspect ratio of barrette. Additionally, the maximum bending moment of barrette increases with the increment of relative density of sand, and the maximum bending moment of barrette decreases with the increment of aspect ratio of barrette.</p>
