Abstract
AbstractColumn base plate connections are used widely. Their design is currently codified by Eurocode 3, though with explicit consideration of only base plates without stiffeners and subjected to a proportional loading path. However, both new and existing steel structures might have stiffened base plates. Besides, there might be the need for analyzing the connection response for a non‐proportional loading path (e.g., increasing seismic loads and constant gravity loads). Therefore, the paper provides a contribution into the development of an analytical model for predicting the response of stiffened base plate connections subjected to a non‐proportional loading path. The paper deals with calculation of the connection rotational stiffness and moment resistance. The objective is pursued through finite element modelling and analysis. Then, the application of a proposed analytical model is shown and a comparison with the finite element analysis results is illustrated and discussed.
