I have seen people are using different approach for load combination method for occasional load case . Like say if below is the load case 1) W+P+T ( OPE) 2) W+P+T+F (OPE ) 3) W+P ( SUS ) 4) L2-L1 ( OCC) 5) L3+L4 ( OCC ) 6) L1-L3 ( EXP ) Then combination different method as mention bellow. a) L4 algebraic & L5 absolute method b) L4 scalar & L5 absolute method c) L4 algebraic & L5 scalar method
My question is which one among three is more technically correct?
From the document Samsul mention I find the Option a & option c as I mention in my previous post will give the same result, occasional stress point of view. Yes I personally checked one file it gives same stress. So both the option can be used.
i think,absolute and scalar combination is the same when calculate stress,cause stress >1.so your a=c,while for b31.1,scalar combination is required for check the occ stress.
