Web Behavior Under Eccentric Edge Load

轧制和组装梁和大梁的腹板可能会受到 平行于腹板平面的边缘压缩补片载荷。 出于实际和/或经济原因， 最小化或避免，除非在关键部分。 是的， 因此，有必要在此载荷下检查未加劲腹板 以确保不会发生局部故障。 人们普遍 假设边缘载荷施加在 网络;这是一个很难实现的假设， 实践 因此，怪癖是不可避免的，必须是 考虑了 这项研究将研究的影响， 偏心率对腹板性能的影响。 实验和 分析研究将导致对网络的理解 在这种负载下的行为。 结构稳定性 研究理事会将提供2000.00美元启动这项研究 项目

Webs of rolled and built.up beams and girders can be subjected to edge compressive patch loads parallel to the plane of the web. For practical and/or economic reasons transverse stiffeners are to be minimized or avoided, except at critical sections. It is, therefore, necessary to check the unstiffened web under this load to insure that no localized failure will occur. It is commonly assumed that the edge loads are applied at the middle plane of the web; an assumption which can be very difficult to achieve in practice. Thus eccentricities are unavoidable and must be considered. This research will study the effect of the eccentricity on the behavior of the web. Experimental and analytical studies will result in an understanding of the web behavior under this type of loading. The Structural Stability Research Council will provide $2000.00 to initiate this research project.
