Flat steel web plates are used in various structural applications such as in plate girders in bridges to transfer large loads across long spans. However, these plates are usually very slim, which makes them susceptible to buckling, a phenomenon that occurs when a long vertical structural element suddenly changes shape under high load. These steel web plates are often used as they are simple to manufacture. However, they often require the use of transverse stiffeners, which help to prevent buckling by increasing the shear strength, or the material’s strength in the direction parallel to the direction of the applied force. These transverse stiffeners introduce additional fatigue, which can cause the material to break down over time. An alternative to flat web plates are corrugated web plates; these do not require the use of stiffeners and therefore do not introduce fatigue. However, the fabrication process for these corrugated plates is complicated and costly. The research I conducted focuses on a different alternative, developed by the Creative and Resilient Urban Engineering (CRUE) Princeton research group, known as Low-Frequency Sinusoidal (LFS) thin steel plates. The lower frequency waves provide for additional shear strength, therefore, eliminating the need for the use of transverse stiffeners, while their fabrication process is not as complex as it is for corrugated plates. The objective of my research was to use Finite Element (FE) structural element analysis to understand the strength and mechanics of LFS plates under varying support and loading conditions.
