Cold‐Bending of Thick High‐Strength Steel Plates

Publication: Journal of Structural Engineering
Volume 116, Issue 1

Abstract

The cold‐bending behavior of thick high‐strength steel plates is studied. Fifteen 1‐in. (25.4‐mm) and three 1.5‐in. (38.1‐mm) thick steel plates are cold‐bent to angles up to 90°, with bend radii of 1.5, 2.5, 3.5, and 5.5 in. Quantities measured include maximum surface strain, load‐displacement relationship, degree of springback, and residual stresses produced by the cold‐bending. Selected equations for predicting maximum surface strain and degree of springback are reviewed, and the values predicted by these equations are compared to test results. The results of the residual stress measurements are presented in a companion paper.
