Shear force‐deformation relationship of concrete‐filled square steel tube beam‐columns under monotonic lateral loading

Abstract This paper proposes a simplified multi‐linear model of a shear force‐deformation relationship for concrete‐filled square steel tube short to slender beam‐columns. To evaluate the behavior of short to slender beam‐columns with a single model, the column member is divided into elasto‐plastic...

Description
Summary:Abstract This paper proposes a simplified multi‐linear model of a shear force‐deformation relationship for concrete‐filled square steel tube short to slender beam‐columns. To evaluate the behavior of short to slender beam‐columns with a single model, the column member is divided into elasto‐plastic part and an elastic part. For the elasto‐plastic part, the deformation at each point is calculated based on the bending moment‐curvature relation model proposed by the author and by employing a newly proposed evaluation formula for curvature magnification. Predictions from the model are found to agree approximately with the experimental results up to large deformations.
