Use this Menu Option to run the ACS SASSI NONLINEAR module for the active model. The postfixes and extensions for the input and output files are set using the Location menu and Extension. All files generated by ACS SASSI RELDISP will be placed in the directory of the active model.
When NONLINEAR starts SASSI User Interface will open a new tab that shows the out of the module. This module is intended to be used in conjunction with other modules in an iterative procedure to produce a nonlinear analysis. The NONLINBAT command. will create a batch file that will set up an generic iterative batch loop for different nonlinear analyses.
The NONLINEAR module is used to analyze structural components using a equivalent linear material property analysis. The main components that can be analyzed are shear walls which are comprised of shell elements, and springs which are modeled using translation springs. The analysis is an iterative procedure similar to the equivalent linear analysis which is also used to analyze nonlinear behavior of soils.
