The deep beam was designed using the strut and tie method (STM) described in Chapter 23 of ACI 318-14. There can be many possible truss models for the given loading and geometry of the deep beams. However, the assumed theoretical STM for the applied loads is shown in Fig. 4 ... The strut-and-tie method of design is based on the assumption that the D-regions in concrete structures can be analyzed and designed using hypothetical pin-jointed trusses consisting of struts and ties inter-connected at nodes.
