Abstract

Many factors have led to revisiting the old problem of shear, including the following: (1) the brittle and catastrophic failure of concrete elements under shear strength, which is a complex phenomenon; (2) the new material advancement, including and not limited to FRP reinforcements; (3) the limited number of rigorous models that exist for such a problem. In this communication, A series of research investigations are briefly described. These works attempted to provide an extended critical shear crack theory model (ECSCT) for a variety of shear situations, such as reinforced concrete using fiber-reinforced polymers (FRP). The critical shear crack theory (CSCT) was selected because it is the base for the new Euro-code. The CSCT is a pioneering mechanical model for both one-way and two-way shear of concrete elements. More than 1000 specimens evaluated under one-way shear were used to verify the ECSCT. Comparisons were made between the model strength predictions and current design codes. In comparison to previous design standards, the model is more accurate and consistent while still making physical sense.
