A new formulation for longitudinally stiffened webs subjected to patch loading using stepwise regression method
This study proposes a new formulation for patch loading of longitudinally stiffened webs using stepwise regression (SR) for the first time in literature. The database for the SR formulation is based on extensive experimental results from literature. The results of the SR formulation are compared with existing models and design codes. It is found that SR formulation gives more accurate results than existing models and design codes.
