Bearings with uplift can be modeled in SAP2000 by using nonlinear link element with gap property. Please note that nonlinear analysis is required to obtain meaningful results for nonlinear links. Please refer to CSI Analysis Reference Manual, chapter "The Link/Support Element - Advanced", section "Gap Property" and Verification Example 6-003 (available via "Help > Documentation > Analysis Verification > Links") for additional information on the subject.
