| Summary: | Slender webs in steel plate girders are prone to local and shear buckling at relatively low shear and thus, need be stiffened to
increase the strength and stability of the girders. The conventional way is to provide vertical stiffeners at specified intervals,
but this practice serves only to prevent the buckling of web. Provision of inclined stiffeners, in addition to improving
buckling resistance, forms a truss-like girder which allows those stiffeners to carry some percentages of forces exerted
in the girder. This paper, therefore, presents the ultimate performance of thin-webbed plate girders containing inclined
stiffeners. Five simply supported plate girders of practical size were tested to failure under concentrated load applied at the
mid-span. This study focuses on the effects of different inclination angles of intermediate stiffeners, |
