Webthe portal. This preserves the load direction as the portal deforms. Students apply either vertical, horizontal or combined loads to the portal, forcing it to bend through the elastic region and into the plastic region where it deforms permanently, experiencing ‘plastic collapse’ and the formation of ‘plastic hinges’. This allows ... WebJul 7, 2015 · PLASTIC DESIGN OF PORTAL FRAMES ALLOWING FOR FRAME INSTABILITY AND STRAIN-HARDENING EFFECTS. Authors: M R HORNE, M W S CHIN, BS 968.
