S_BucklingLoad

Purpose

general script for determining the buckling load of a structural model

Synopsis

This is a script file.

Description

BUCKLINGLOAD general script for determining the buckling load of a structural model
  the scripts sets up the linear and the geometric stiffness of a structural model with
  its geometry and boundary conditions in MODEL and its element properties IN ELEMDATA;
  before invoking the script it is necessary to define the reference load in Loading,
  so that it can be applied in Step 2 for determining the axial forces in the elements
  and with them the total structure stiffness Kt in the undeformed configuration;
  the geometric stiffness Kg is determined by subtracting the initial stiffness Kl from Kt

Cross-Reference Information

This function calls:

• Structure performs requested action on group of elements
• Initialize_SolStrat default values for most solution strategy parameters
• Initialize_State initialize state variables of structural model and create STATE
• S_InitialStep script for initial step of incremental analysis
