Columns within a structural frame, be they interior or perimeter columns, can provide sway resistance. For example if you were to design semi regid connections each subframe of columns and beams would effectively start to act in a 'portalised' manner and stiffen the building. It is wrong to...

Like most things in life there is either an easy or hard way to do something. The idea of welding two tubes that don't even sit snuggly together is ludicrous. It is unlikely most engineers would consider welding two tubes together as a simple solution. My point regarding longitudinal...
I read with interest all the various opinions as to what is occurring when load is applied to your double tube arrangement. I do feel however the first analytical decision should be to consider your size restrictions to ascertain the maximum size of your beam (depth and width) you can use. Once...
Although it is a realtively straight forward calculation using simple statics to find moments and shear the evaluation of deflection at the end of an overhanging propped cantilever is not as straight forward. There are no simple formulae to give the deflections of a overhanging propped...
