Define Input tab
Used to define general definition and member specific parameters for a pushover analysis.
General Input Parameters
Select this control to add general parameters for the entire structure.
Setting  Description 

Type of Frame 
Select either a fully restrained Moment Frame (FR) or a (Concentric) Braced Frame (CBF) to defined the type of steel frame. 
Geometric NonLinearity Effect 
Select either Ignore Effect, if nonlinear effects are not to be considered, or Include Effect, if nonlinear effects are to be considered. 
Displacement Tolerance 
(For when Geometric NonLinearity Effect is considered only) Set this option to specify a displacement tolerance for convergence, in current input units. 
No. of Iterations 
(For when Geometric NonLinearity Effect is considered only) Set this option to specify a target number of iterations for geometric nonlinearity convergence. 
No. of Iterations for KG Matrix 
Set this option to specify the number of iterations to be performed for geometric stiffness, KG, matrix. The value is a integer, with a maximum value of 50. 
Max. no. of Analysis Cycles 
Set this option to specify a maximum number of cycles to be considered during the strain hardening stage for the load increment stage. 
Displacement Incremental Value 
Set this option to include intermediate displacement increments, in current units of length, at which the program will record analysis results for postprocessing. 
Base Shear Incremental Value 
Set this option to include intermediate base shear increments, in current units of force, at which the program will record analysis results for postprocessing. 
Print Output Results 
Set this option to print analysis results for the final state for a nonlinear static analysis.

Member Specific Parameters
Select this control to add parameters for members which will be assigned later.
Setting  Description 

Expected Yield Stress 
Expected yield strength of the material based on Section 5.3.2.3 and Tables 51 and 52 of FEMA 356. 
Effective Length Factor for Member (Y/Z) 
The effective length factor, k, defined for any member in either the local Y or local Z direction.
