Abstract: The effect of residual stress on the flexural buckling strength of cold‐formed steel columns is studied. Based on the results of 93 column tests and the measured residual stresses, significant relation is observed between ...

Abstract: An extensive experimental investigation of the residual stresses in cold‐formed steel members is presented. The electrical discharge machining (EDM) technique is used to cut coupons for residual stress measurement. As ...

Abstract: This paper presents a detailed description of an experimental study of the flexural buckling strength of cold‐formed steel columns. A total of 68 columns and 25 stub columns are tested. It is observed that some types of ...

Abstract: Based on the approximate Jezek's method of beam‐column theory, a computerized analysis was performed to determine the maximum strength of cold‐formed steel columns. In this study, the effect of residual stress and initial ...

Abstract: This paper presents the results obtained from the residual stress relief tests on 21 welded structural steel joints: 17 butt‐welded, two tee, and two corner joint specimens. The A572 grade 50 structural steel plates of two ...

Abstract: Acoustic-emission (AE) technology is considered a potential new testing method to monitor the integrity of concrete materials. This study is devoted to the investigation of the AE Kaiser effect in fly-ash cement mortar ...

Abstract: An experimental investigation of the residual stresses in severely cold‐bent thick high‐strength steel plates is presented. Both the sectioning and the hole‐drilling methods are used for residual stress measurement; the ...

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 ...

Abstract: This study investigates the shear strength of composite steel and concrete members in which the steel shape is fully encased in concrete. Two types of shear failure—diagonal shear and shear bond—are examined in this study. ...

Abstract: Presented herein is an experimental study that focuses on the shear splitting failure of composite concrete encased steel beams. Nine full-scale specimens were constructed and tested in this study. Significant horizontal ...
