Dec 10, 2018 #1 umeshlamichhane Civil/Environmental Dec 10, 2018 13 what is post stiffness ratio? waht is its use?
Dec 11, 2018 #2 Erik Panos Kostson Structural May 18, 2018 389 Do you perhaps mean post-yield stiffness ratio? If it is that, a quick search in the sap2000 help (or on the internet), will probably give you something like this: "The post-yield stiffness ratio applies for nonlinear analyses. It is the post-yield stiffness divided by the initial stiffness." Should mention that this quote is taken for rubber isolators in SAP2000, so it probably does not apply to beams. Upvote 0 Downvote
