Theoretical analysis of vertical load-carrying behavior of rectangular barrette groups

Unlike a circular pile, the cross section of a rectangular barrette is nonaxisymmetrical. Therefore, not only the pile spacing but also the pile shape and the pile group layout will have influence on both the load-carrying behavior and the pile group effect of barrette groups. In order to analyze these influencing factors, a calculation method is proposed for obtaining the load-settlement relationship of the barrette groups with or without a rigid cap, using the Mindlin equation and the static force equilib...
