Introduction
The following Analysis commands are added to the interpreter to create the Analysis and perform the analysis:
General commands
This command creates the reliability domain in which the sensitivity, reliability and optimization components are kept. This reliability domain is parallel to the finite element (FE) domain in OpenSees. Currently, the commands for stand-alone sensitivity analysis (e.g., sensitivityIntegrator, sensitivityAlgorithm) are set in the reliability domain only and, thus, the ‘reliability’ command must be used before any stand-alone sensitivity analysis.
In DDM-based FE response sensitivity analysis, the sensitivity parameters can be material, geometry or discrete loading parameters.
Several uniaxial materials are available for DDM-based FE response sensitivity computation.
Material Commands
This command is used to construct a uniaxial Menegotto-Pinto steel material object.
This command is used to construct a uniaxial smoothed Popovics-Saenz concrete material object. Reference: Zona A., Barbato M., Conte J.P.
