本文对纵向加筋钢板在单向均布边压作用下的强度进行了理论和试验研究。这些板可以被认为是箱梁桥中的翼缘板。考虑残余应力的弹塑性屈曲理论确定了加筋板的抗压强度。采用Bijlaard变形理论来描述屈曲板的弯矩-曲率关系。除了理论研究外，还计划了25个破坏试验，采用3-5个等距平板式纵向加劲肋的简支板。描述了到目前为止完成的这25个测试中的12个。
This paper presents a theoretical and experimental study on the strength of longitudinally stiffened steel plates subjected to uniformly distributed edge compression in one direction. The plates may be thought of as flange plates in box girder bridges. The compressive strength of stiffened plates is determined from an elastic-plastic buckling theory with residual stresses taken into consideration. Bijlaard's deformation theory is adopted to describe the moment-curvature relations of buckled plates. In addition to the theoretical study, 25 failure tests were planned using simply supported plates with 3-5 equidistant longitudinal stiffeners of flat type. The 12 of these 25 tests completed to date are described.
