This manual is intended to outline the basic commands currently available within the OpenSees interpreter for performing DDM (Direct Differentiation Method)-based response sensitivity analysis. This interpreter is an extension of the Tcl/Tk language for use with OpenSees. The existing Tcl commands for Finite Element response-only computation are described in the OpenSees user’s guide available online at http://opensees.berkeley.edu and, thus, are not repeated in this document. The notation used herein is the same as that used in the Tcl commands manual for response-only computation. Only new Tcl commands for DDM-based response sensitivity computation are presented and explained in detail.
This manual is subdivided as follows:
- DDM-Based Response Sensitivity Computation Tcl Commands: commands added to the interpreter for response sensitivity computation.
- Demonstration Examples: five demonstration examples used to illustrate and validate the DDM-based response sensitivity analysis components implemented in OpenSees.
- Extension of an existing material,cross section, and element for DDM-based: the necessary functions needed for implementation of the DDM-based response sensitivity computation are listed and explained.
- Tcl input files for the provided application examples: Tcl input files for the above five application examples.
