Exploring Trigonometric Methods in Suspension Bridge Analysis

There are a couple of ways to analyze suspension bridges. As previously discussed (Uniqueness and Difficulties of Suspension Bridge Analysis), the deflection theory proposed by Melan and solved by Moisseiff is one of the first. The second one may be trigonometric methods proposed by Timoshenko (Theory of suspension bridges, Journal of the Franklin Institute, Volume 235, Issue 4, April 1943, Pages 327-349). In this article, a brief explanation of trigonometric methods and related excel, and the example bridge dimensions will be provided.

7 Reasons why learning a Finite Element Analysis software is important for a modern day engineer?

midasBridge TeamSep 26, 2023

Finite Element Analysis or FEA is a numerical method used in engineering to solve complex problems by dividing a system or structure into smaller, simpler, and more manageable parts called finite elements. FEA involves the application of mathematical algorithms and computer software to simulate and analyze the behavior of a system under various conditions.
