Development of Design Charts for Rectangular Barrettes
A cast-in-place-reinforced concrete pile that can withstand axial loads and high moments is called a barrette. This kind of foundation is suitable for all sorts of soil, including boulders and alluvial soil. When very heavy column loads need to be transmitted to a very deep bearing stratum, conventional piles can become unworkable and uneconomical. When there is a high water table and there are a variety of soil types, including sands, silts, and clay, the problem gets more challenging. In some circumstances, in addition to resisting vertical loads, the designer would also need the foundation elements to withstand lateral loads and bending moments in a preferred direction. In these circumstances, rectangular shapes would be preferable to circular shapes. A single laterally loaded large-section barrette may take the place of a group of circular piles due to the barrette's better resilience to lateral stresses. To compare ultimate lateral capacities and calculate the percentage reduction in cross-sectional area due to replacing a group of the circular pile with a single rectangular barrette, 3D barrette models of various sizes and groups of circular pile models were created in the MIDAS GTS NX programme and used in this study. Results showed that a group of circular piles may be replaced by a single rectangular barrette with reduced cross-sectional, which may be cost-effective alternative for conventional circular piles.
