design against lateral wind loading
(OP)
I am designing a 4-storey steel frame structure, just wondering whether is better to use diagraphm or shear wall to design against lateral wind loading.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: design against lateral wind loading
Shear walls are vertical elements that receive lateral forces from diaphragms (floors/roof).
Not sure what exactly is your question. Are you asking about what type of lateral bracing to use?
RE: design against lateral wind loading
If you choose to go with the eccentric brecaed frame, and assuming you follow all the requirements listed in the AISC Seismic spec, for the eccentric frame, it qualifies as a "special type" frame which reduces the seismic forces on the structure. Which, in turn will reduce the forces on the members, which will in turn reduce the forces to the foundations, etc......
RE: design against lateral wind loading
A better question would seem to be, which lateral system is best, moment frame, braced frame, or shearwall system?
Since you are designing a steel frame, any option works. More information would be helpful though to decide.
