Abstract
It has been recognized that the mechanical properties of sheet steels and the structural strength of cold-formed steel members can be influenced by strain rate. For studying the local and postbuckling behavior of the stiffened and unstiffened compression elements under dynamic loading condition, 97 stub columns which were assembled from the same material have been tested under different strain rates. In order to study the structural behavior of hybrid cold-formed stub columns, a total of 144 specimens were investigated. In addition, 52 drop silo tests of stub columns were conducted at General Motors Corporation (GM). The results showed that the strength of stub columns increases with increasing strain rate. The amount of increase was found to be dependent on the material yield strength, the type of steel, the stress-strain relationships, the width-to-thickness ratio and the type of compression element, and the strain rate used in the test. © 1998 Elsevier Science Ltd.
