Deep beam is designed by flexure design method and shear provided by concrete (Vc) for deep flexure members are provided in special provisions section of 11.8 in ACI 318‐99 [1]. But in later version of ACI (after ACI 318‐99) deep beams shall be designed either by taking into account nonlinear distribution of strain or by Appendix A of Strut‐and‐Tie Models (STM). Different from ACI 318‐99, there is no specific provision of design method for deep beam. This study aims to find the different and efficiency of deep beam design based on variation of parameter compiled from many samples selected between ACI Traditional design method and Strut‐and‐Tie Models.
