This paper presents a new resistance model for steel plate girders subjected to patch loading. The model aims to correct the EN 1993‐1‐5 formulation concerning the resistance to transverse forces with the help of findings presented in several doctoral studies on this topic. In addition, a statistical calibration of the new model is addressed. This calibration includes a new proposal for the resistance function χ ‐ λ . The proposal is conceived for fulfilling safety levels of the partial safety factor that match the current values included in EN 1993 for instability‐related problems. These new proposals are in accordance with the design philosophy found in EN 1993‐1‐5 for the design of plated structures.
