At the ends of dapped-end beams, the transfer of load from the support into the beam is a D-region. The STM is excellent for modeling such a region. In a number of applications, for example parking structures, dapped-end beams are used in conjunction with inverted T-Beams. At each point where the load of the dapped-end beam sets on the inverted T-beam, a D-region is formed. The following example used ACI 318-02 Appendix A to design both the end region of thedapped-end beam as well as the tie back and vertical reinforcement needed for each point load on the inverted T-beam. Conventional B-regions in the dapped-end beam are designed using conventional AC1 beam design.
