Tests on plate girders containing web openings and inclined stiffeners

Research output: Contribution to journalArticle

Abstract

This paper presents the ultimate load behaviour of perforated steel plate girders with inclined stiffeners. Ten simply supported plate girders were tested to failure subjected to a single concentrated load applied at the centre of the girder span. The circular shape of web openings of various diameters, viz., 100 mm, 150 mm, 200 mm and 250 mm were located at the centre of every web panel in the girder specimens. The main focus of this study was to investigate the effects of different inclination angles of intermediate stiffeners on the post-buckling behaviour. The inclination angles of intermediate stiffeners measured from the bottom flange, viz., 90o, 75o, 60o, 45o and 30o were considered in the test series. Due to the effects of such inclinations, the variations of strength, failure characteristic and load-deflection response were investigated. Test results showed significant increases in the ultimate strength to the extent of 92% as the angle of the inclined stiffeners reduced.
