Lateral Deflection of Moment Frames
Lateral Deflection of Moment Frames
(OP)
Lateral deflection of moment frame is difficult to handle. Calculation showed that moment frame is 100% expensive than ordinary braced frames. Is there any other option expect to moment frame when we have no option to provide bracings.

What type of building is this?

yes portal frames are more expensive. But there is only one type of building that is the cheapest to build (a braced box), but as long as architects are involved you will never be designing that building.
Cost comparisons only have meaning if you are comparing between alternatives, comparing to a system that is no good for your situation is meaningless.
As jike suggested, use bracing where you can to minimise the requirements for portal frames.
