convert combs to nonlinear cases or use combs of individual nonlinear cases?
convert combs to nonlinear cases or use combs of individual nonlinear cases?
(OP)
Dear all, I'm looking at modelling a cable stayed bridge in SAP2000, one of the issues seems unclear to me is about creating the nonlinear loadcases. I'm thinking to make individual nonlinear cases first (i.e. dead&prestress, wind, thermal, traffic etc.), then to make combinations of them, rather than what I did before to make combinations first then convert them to nonlinear cases. This was a consideration to use the load envlopes later. I am puzzled by the differences between this two approaches and their impact to the results,can anyone please advise me? Thanks.
