Product Description
Types of Portal Frame
Portal frame featuring a mezzanine floor
Often office accommodation sits within a steel portal frame structure that utilises the use of a mezzanine floor.
Pitched roof symmetric portal frame
These frames are usually fabricated from UB sections with a large eaves haunch section cut from a fabricated plate or rolled section. 25 to 35 m are the most effective and common spans.
Crane portal frame featuring column brackets
In the case where a travelling crane of up to 20 tonnes is required, brackets can be attached to the columns of the frame to support the crane rails. By using a tie member or rigid column base, this reduces the eaves deflection.
Tied portal frame
The horizontal movement of the eaves present in a tied portal frame along with bending motions in the columns are significantly reduced. Tie portal frames can be highly effective in limiting the spreading of a crane-supported structure.
Mono-pitch portal frames
Mono-pitch portal frames are generally used for small spans and because of their proximity to other buildings in the area. As a simplistic variation of the pitched roof portal frame, these frames tend to be ideal for smaller constructions of up to 15m span.
Propped portal frame
In the case where the span of the portal frame is larger than usual and you don't have to provide a clear span, a propped portal frame is suitable. This reduces the size of the rafters along with the horizontal shear present at foundation level.
Mansard portal frame
Mansard portal frames are generally chosen in the case of large and clear height mid-spans where the eaves height of a building is minimised in comparison.
Curved rafter portal frame
Portal frames can be constructed with curved rafters which are implemented generally for architectural reasons. Due to transport limitations however, rafters that are longer than 20m usually require splices.
Cellular beam portal frame
Rafters can be fabricated using cellular beams and this is usually the case for aesthetics. However, they may also be preferred for long spans and where transportation is limited which imposes a requirement for the use of splices. They should be carefully detailed in order to preserve their architectural features and be of an elastic design.
