Re: METAL BUILDING DESIGN METHODS

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Dear Juan José
Nowadays the design of steel buildings is oftenly  determined by structral
software incluidng stess forces ,moments and disions of members.
There are some manual methods that simplify  and make easy our work overall
for lateral loads. ( FRAME METHOD, that suppose hinges in the centre of the
column spans )
Concerning  web members, some determinations  that involves  equilibrium of
internal forces are used.

Regards
(Un gran abrazo)
