A. To specify a nonlinear cable analysis
To specify a nonlinear cable analysis using the advanced features in STAAD.Pro, use the following steps.
Only one primary load case is permitted for a nonlinear cable analysis. A CHANGE command must be used with a new nonlinear cable analysis for each additional primary load case to be analyzed.
-
Either:
or
on the Analysis and Design ribbon tab, select the Analysis Commands tool in the Analysis Data group
- Select the Perform Cable Analysis tab.
- Select the Advanced Cable Analysis option.
- (Optional) Set the options for Use Modified Newton-Raphson method and Use Geometric Matrix (Kg) as needed.
- (Optional) Type values for the Steps, Eq-Iterations, and Eq-tolerance fields as needed. Default values are assumed for each when not specified.
- Select the Print Option you want to use.
- Click Add. The advanced cable analysis command is added to the input file.
Add a change command and a new primary load case to analyze additional load cases using a nonlinear cable analysis. Then repeat this procedure to specify another nonlinear cable analysis.
