Braced frames are a very common form of construction, being economic to construct and simple to analyse. Economy comes from the inexpensive, nominally pinned connections between beams and columns. Bracing, which provides stability and resists lateral loads, may be from diagonal steel members or, from a concrete 'core'.

Bracing steel portal frame

Bracing, which provides stability and resists lateral loads, may be from diagonal steel members or, from a concrete 'core'. A braced frame is a structural system commonly used in structures subject to lateral loads such as wind and seismic pressure. The members in a braced frame are generally made of structural steel, which can work effectively both in tension and compression. The beams and columns that form the frame carry vertical loads and the bracing system carries steel portal frame - roof bracing question.

Portal frames are similar in construction to a rigid frame with two columns and a rafter. As this is an expensive bracing solution, portal frames are used when openings prevent cross bracing from being used.

Allowable wall-bracing length must be multiplied by a 0.80 factor. Portal frames. Portal frames are used when you have the same situation as a wind column, but a wind column does not provide enough support. These frames are usually used on larger buildings and steel buildings with very high snow or wind loads. When x-bracing is not allowed in a wall and a wind column is not strong enough, a portal frame is used.
