      <title>SIMPLIFIED BUCKLING ANALYSIS OF PLATE WITH COMPOUND EDGE STIFFENERS</title>
      <link>https://trid.trb.org/View/442828</link>
      <description><![CDATA[Turning the free edge of the unstiffened flange inward or outward to form a lip, can substantially improve the local buckling resistance of a member, thus leading to greater efficiency.  This is one of the most common edge stiffeners, elements stiffened by a compound edge (i.e. double-fold lip) is examined both theoretically and experimentally.  An outline of a series of tests on compound-edge-stiffened plate elements of various geometries is given and some load-end compressive displacement paths are compared with the theoretical predictions. Reasonably good agreement is obtained between the experimental and theoretical results.  Comparisons of the theoretical predictions with work done by other researchers are also presented in this paper.]]></description>

      <title>TRIPPING OF ASYMMETRICAL STIFFENERS UNDER COMBINED LOADING</title>
      <link>https://trid.trb.org/View/398415</link>
      <description><![CDATA[This document reports on a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The method of analysis is based on the principle of minimum total potential. First yielding was used as the criterion of ultimate strength. Instability under axial loading was investigated for the symmetrical (Tee) and asymmetrical (Angle) stiffeners. Angle stiffeners showed greater capacity than Tee stiffeners for lower values of the slenderness ratio (L/r), but lower capacity for higher values of the slenderness ratio, especially after consideration of the deformations of the stiffener web. Under combined axial and lateral loads, there was a significant decrease in the capacity of asymmetrical (Angle) stiffeners because of the distortion of the cross section as compared to the undeformed or symmetrical sections. A modified effective width concept was introduced into the analysis to consider the effect of postbuckling plate deformations under combined loading condition. The effect of initial imperfections of stiffeners was also included.]]></description>

      <title>ULTIMATE LOAD ANALYSIS AND DESIGN OF STIFFENED PLATES IN COMPRESSION</title>
      <link>https://trid.trb.org/View/182499</link>
      <description><![CDATA[This thesis reviews the stability requirements in the Merrison rules for stiffened plates in box girders.  The special features of the stiffened flange are identified. From the non-linear behaviour of its various components, an analysis model of the whole flange is assembled.  The large-deflection plate theory is used to obtain the influence of initial imperfections and welding stresses on the behaviour of plate panels up to their collapse.  The orthotropic response of the whole stiffened flange is quantified by extending the large-deflection theory to orthotropic plates.  The effect of varying axial load due to bending moment gradient is derived from energy considerations of a Fourier series deflected shape of stiffener.  Eccentricity of axial loading, transverse loading and random patterns of imperfections in adjacent spans are analysed from the moment-rotation compatibility of continuous beam-columns.  Limitations to avoid premature torsional buckling of flat stiffeners are derived from plate theory and extended to cover other types of stiffeners, flexural restraint from the flange plate, and a non-uniform stress distribution over the depth of the stiffeners.  A series of box girder tests at Imperial College is described. Good correlation is obtained between measured and predicted longitudinal welding stresses. Finally, simple rules are given for the design of stiffened compression flanges, and compatible fabrication tolerances on imperfections of plates and stiffeners are also recommended.

      <title>BUCKLING OF LOCALLY IMPERFECT STIFFENERS IN PLATES</title>
      <link>https://trid.trb.org/View/59689</link>
      <description><![CDATA[An analysis is presented of the elastic buckling of infinitely wide stiffened plates.  The analysis is based on a simplified model of the panel and seeds to determine the interactive behavior of the overall mode of buckling and the local buckling of the stiffener outstands.  A high degree of imperfection sensitivity is predicted, particularly for geometries in which the local and overall critical loads are close.  The predictions of the analysis are in good agreement with experimental test results showing that the approximations inherent in the analytical model do not lead to significant errors. /ASCE/]]></description>
