Drilled Shaft Responses under Pre-Torsion Lateral or Vertical Loads
Drilled shafts are frequently designed with single load consideration. Insufficient research attention has been rendered to the effects of load sequence under combined loading (Abdel-Rahman and Achmusand, 2006). The effects of load sequence under combined loading on the performance and design capacity of drilled shafts are important, however, and warrant focused research consideration. Over the last decade and a half, the University of Colorado Denver (UCD) has devoted considerable research effort in deep foundations, driven piles, and drilled shafts, including the subject matter addressed in this paper (Volmer, 2011). Volmer (2011) performed a study on the effects of combined loading relative to the torsional response of drilled shafts, using a developing nonlinear finite element analysis (FEA) program, SSI3D, for both cohesive and cohesionless soils. This study finds the influences of combined loading to be significant in some cases and highly dependent upon the soil type. These research findings, in terms displacement and capacities, aim at providing scientific input for the service and strength limits in load resistance factor design (LRFD) in the current AASHTO Bridge Design Specifications.
