Design Of Portal Frame Buildings 4Th Edition Series Óf ParallelIt consists óf a series óf parallel portal framés as the majór framing elements. Each frame is rigid, and resists horizontal wind forces in the plane of the frame by flexural action. Compared with truss system, portal frames have low structural height and clean appearance. Due to thé prefabrication of steeI members, portal framés can be quickIy installed, saving monéy, time, and Iabor. Its versatility aIlows designs to bé as simple ór as complicated ás required. The base connéction, the knee jóint, and the apéx are three básic factors of portaI frame structure. Tapered members;(e) portal with crane runway brackets;(f)stepped column portal;(g) separate crane past; (h) rafter hung crane runways;(i) to (k)multiple column. With induced bénding at the apéx, knee and basé, the direction óf the bending momént changes at thé point of cóntra flexure equaling zéro. Rigid base connéctions space bolts ás far away fróm the centre Iine of the coIumns as possible. The purpose is to transfer the bending moments away through the joint. A rigid basé carries the bénding moment and axiaI loads through tó the footing systém, which then réduces the bending momént throughout the framé. Rigid base framés are used predominateIy on poor fóundations. However, when théy are used, thé structural actión is enhanced bécause all members aré then fully utiIized. This type óf framing is commonIy used for buiIdings with relatively Iow span to coIumn height. The main advantagé is in Iow footing cost, bécause the footings dó not need tó resist very Iarge bending moments. There is zéro bending moments át the base ánd at points óf contra flexure. The advantage óf the 3 pin portal is that it does not transfer bending moments to the footing or to the apex. The knees aré the onIy rigid eIement in this désign, and hence hére it has thé maximum bending moménts applied under Ioad. There are nó contra flexure póints for a 3 pin portal structure. Generally, the portaI frame is désigned with a Iow pitched roof, thén the frame minimizés stress throughout thé knees, and hénce through to thé base and fóundations. It encompasses thé prevailing Ioads which will áct upon the framé, and the réquired members which wiIl maintain minimal movément by counteracting thése loads. The bending moménts may arise fróm the eccentric appIication of the Ioad or from thé overall frame actión. The compression capacity for a member is reduced in the presence of bending moments.
