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.
|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 Non-Linearity Effect||
Select either Ignore Effect, if nonlinear effects are not to be considered, or Include Effect, if nonlinear effects are to be considered.
(For when Geometric Non-Linearity Effect is considered only) Set this option to specify a displacement tolerance for convergence, in current input units.
|No. of Iterations||
(For when Geometric Non-Linearity 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 post-processing.
|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 post-processing.
|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.
|Expected Yield Stress||
Expected yield strength of the material based on Section 22.214.171.124 and Tables 5-1 and 5-2 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.
