VERSION HISTORY
LIRA-FEM
Pushover Analysis
-
For Pushover Analysis, new option to set the user-defined steps for application of horizontal earthquake load and to take into account the damping ratio.
Pushover Analysis for earthquake load
-
For Pushover Analysis, it is possible to use iterative FEs; previously, only step-type FEs were used. This option, for instance, enables the use of nonlinear hinges and inelastic springs to account for the local plasticity.
