• Abstract:
  The strut-and-tie method (STM) is a design method intended to provide realistic strength and detailing requirements for deep structural members subjected to non-linear distribution of strain by considering idealized flow of internal forces. Axially loaded concrete struts and ties are used to represent the compression and tension fields in structural members, and it forms three-dimensional (3D) structure of strut-and-tie models in drilled shaft footings. However, current STM provisions were formulated based on research into deep structural members (such as deep beams) designed with two-dimensional (2D) strut-and-tie models, and there are no experimentally verified design guidelines for designing the deep structural members with 3D strut-and-tie models.
