Based on Fitzgerald (2002), pp. 1-139 to 1-141.<br /> <br /> Original illustration for [[Progressive collapse]], level 4 Expert.<br /> <br /> * Source basis: Fitzgerald (2002), pp. 1-139 (shape factor 1.14, factor of safety 1.5, 1.71, fixed-end elastic moments), 1-140 (w_u = 16 M_p/L²) and 1-141 (w_u = 8 M_p/L², fixed ends twice the capacity); values calculated by Fire Safety Academy<br /> * Alt text: Bar chart of design, first-yield and collapse loads for a simply supported and a fixed-ended steel beam; the fixed beam collapses at 2.28 times its design load.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
