General Link Properties
General Link elements are used for modeling damping devices, base isolators, compression-only or tension-only elements, plastic hinges, soil springs, etc. General Link elements can be assigned to linear and nonlinear properties using spring properties.
Nonlinear Analysis Control
Users can quickly apply settings for nonlinear analysis in the Nonlinear Analysis Control function. Iteration methods for nonlinear analysis are provided with Newton-Raphson, arc-length, and displacement control. Three different methods (Energy Norm, Displacement Norm, and Force Norm) are provided to adjust the convergence of analyses.
midas Civil provides pushover analysis to support a performance-based design. The Pushover Global Control function provides detailed options for analysis. After completing the analysis, the user can review the analysis results in tables, graphs, texts, etc.
