Buckling of stiffeners in plate girder bridge

WebNov 12, 2024 · One of the parameters of the economic design of steel I-girders is the use of thin webs. However, in large spans, the use of deep I-girders with thin web leads to the buckling of the web. In order to achieve out-of-plane stiffness and shear buckling resistance without the use of stiffeners or increasing the thickness of the webs, one … WebA.1.3 Buckling of Rectangular Plates under Shear 513.

WebThe phenomenon of shear lag refers to the increases of the bending stresses near the flange-to-web junctions, and the corresponding decreases in the flange stresses away from these junctions. In the plated structures with wide flanges, such as in the WebWilson [9] realized the first research on post buckling behavior of plate girders and described post buckling strength of webs with stiffeners in shear in 1886. In 1931, Wagner [10] developed uniform diagonal tension theory to identify strength of structures having very thin web panels and rigid flanges under pure shear. laboratory concrete testing https://tammymenton.com
