What is NERA: Nonlinear Earthquake Analysis Tool about?
The document describes the NERA computer program for nonlinear earthquake site response analysis of layered soil deposits. NERA uses a nonlinear and hysteretic material model developed by Iwan and Mroz to simulate soil behavior during cyclic loading, representing an improvement over equivalent linear models. The program is implemented using FORTRAN and a spreadsheet interface in Excel. It allows users to model soil profiles, specify earthquake ground motions, define nonlinear stress-strain properties for ea
