Abstract:
Park, H.-G., and Choi, K.-K., Concrete International, V. 39, No. 9, September 2017, pp. The ACI 318-14 Code specifies the use of 14 equations for evaluating one-way shear strength. These detailed equations are inconvenient to use and need to be revised and combined into a unified method. This article presents a shear strength model based on the concrete compression zone failure mechanism. The shear strength of the compression zone is defined by a material failure criterion considering the effect of the compressive normal stress developed by flexural moment.
