Introduction
The following Analysis commands are added to the interpreter to create the Analysis and perform the analysis:
General Commands
reliability Command
- 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.
parameter Command
- In DDM-based FE response sensitivity analysis, the sensitivity parameters can be material, geometry or discrete loading parameters.
addToParameter Command
- In case that more objects (e.g., element, section) are mapped to an existing parameter, the following command can be used to relate these additional objects to the specific parameter.
updateParameter Command
- Once the parameters in FE model are defined, their value can be updated.
sensitivityIntegrator Command
- Define the sensitivity integrator.
sensitivityAlgorithm Command
- Define the sensitivity algorithm.
recorder Command
- To record the nodal response and response sensitivity.
Material Commands
UniaxialMaterial Commands
- Several uniaxial materials are available for DDM-based FE response sensitivity computation.
SteelMP Command
- This command is used to construct a uniaxial Menegotto-Pinto steel material object.
SmootPSConcrete Command
- This command is used to construct a uniaxial smoothed Popovics-Saenz concrete material object.
