Subject: Portalising, portalise construct. Portalising the frame with rigid joint beam to column connections is an alternative way to provide the stiffness to resist lateral loads but this is less efficient in material use than braced walls, and it imposes fixity on the plain beam and column sections, increasing the beam sizes that would otherwise have been sized compositely as well as adding complexity to the connections. It can occur however that architecture requires a close centre perimeter column arrangement of say 3 m centres, and it would then be opportune to portalise this to provide a stiff perimeter to resist lateral loads.
