From the Fundamentals of Bridge Engineering curriculum
<h2>Structural Analysis</h2>
<p>Every bridge must balance two primary forces: <b>Compression</b> (pushing together) and <b>Tension</b> (pulling apart).</p>
<h3>Bridge Types & Forces:</h3>
<ul>
<li><b>Suspension Bridge:</b> Main cables are in high <b>tension</b>; Towers are in high <b>compression</b>. Best for long spans (e.g., Golden Gate).</li>
<li><b>Arch Bridge:</b> The entire structure is in <b>compression</b>. The force is transferred outward to the abutments.</li>
<li><b>Beam Bridge:</b> The top of the beam is in compression, bottom is in tension. Limited span length.</li>
</ul>
Frequently asked about Forces: Tension and Compression
Structural Analysis Every bridge must balance two primary forces: Compression (pushing together) and Tension (pulling apart). Bridge Types & Forces: Suspension Bridge: Main cables are in high tension ; Towers are in high compression . Best for long spans (e.g., Golden Gate). Read the full notes above for the details.
Forces: Tension and Compression is a core topic in Fundamentals of Bridge Engineering. Most exam papers test it via a mix of definitions, worked examples, and applied problems. The notes above cover the high-yield sub-topics, common pitfalls, and the kind of questions examiners typically set.
