Scope: This guide provides information about nonlinear modeling parameters for: (a) Special moment frames extracted from ASCE/SEI 41@ for which definitions and requirements are converted to those of the codes for the design of new concrete buildings (b) Special structural walls and coupling beams extracted from ASCE/SEI 41@ for which definitions and requirements are converted to those of the codes for the design of new concrete buildings (c) Special moment frames and structural walls developed from the latest experimental databases of structural components compliant with the requirements of Chapter 18 (ACI 318-14) for earthquake-resistant structures. In regards to (c)@ the mean and mean minus one standard deviation modeling parameter values are provided for these code-compliant specimen databases in an effort to demonstrate a quantitative representation of data distribution for the LDP. The LDP can select modeling parameters based on ASCE/SEI 41@ or the experimental database@ depending on project constraints@ jurisdiction requirements@ or both. The modeling parameters in this guide are meant to be used for the analytical modeling of structural components in earthquake-resistant systems as described. The guide@ however@ does not describe global behavior or provide interaction between different systems in the buildings@ for example@ diaphragms and moment frames.
