Based on Gross and McAllister (2005), p. 296, and Zarghamee, Kitane, et al. (2005), p. 310.<br /> <br /> Original illustration for [[Tensile membrane action]], level 4 Expert.<br /> <br /> * Source basis: Gross and McAllister (2005), p. 296 (sagging, pull-in forces at column connections, inward bowing; floor in tension does not restrain the wall), p. 89; Zarghamee, Kitane, et al. (2005), p. 310 (floors with large sag did not restrain columns from buckling)<br /> * Alt text: Section through a tall building edge: several heated floors sag between core and exterior wall and pull the wall columns inward into a bow.<br /> <br /> == Licensing ==<br /> New drawing by Fire Safety Academy. © Fire Safety Academy.</div>
