Abstract This study uses symbolic regression with a strut-and-tie model to predict the shear strength of reinforced concrete deep beams (RCDBs) and corbels (RCCs). Previous studies have proposed two distinct types of models for estimating shear capac

Reinforced concrete deep beams (RCDBs) are vulnerable to brittle shear failure and can cause the beams to fail diagonally. This study investigates the effectiveness of shear-strengthening techniques in RCDBs by using galvanized corrugated sheets (GCS
