ANS:
Portal Frame or Frame structures are the structures having the combination of beam, column and slab to resist the lateral and gravity loads. These structures are usually used to overcome the large moments developing due to the applied loading.
1. Rigid frame structure
Which are further subdivided into:
- Pin ended
- Fixed ended
2. Braced frame structure
Which is further subdivided into:
- Gabled frames
- Portal frames.
This Frame make structure Flexible and they have good results in Earthquake. Further there are 2 types frames based on Sway:-
- Portal frame
- Non-portal frame
Portal frames are primarily used for steel or steel-reinforced precast concrete structures. Portal frames is a set of entirely different concept, where in for designing you need to analyse it for sway considering it as an indeterminate structure.
In simple words, framed structure can be a portal frame or a non-portal frame. Portal frame tends to sway sideways because of the absence of any horizontal forces so you need to design it for sway, whereas non portal frame do not sway.
Normal beams and column structure:-
A load-bearing wall or bearing wall is a wall that bears a load resting upon it by conducting its weight to a foundation structure. The materials most often used to construct load-bearing walls in large buildings are concrete, block, or brick.
An example photo of load bearing structure:-
Now let's see a quick image which shows the difference between them in one pic:-
