Introduction

This page contains the contribution to OpenSees from the research group of the University of California San Diego (Prof. Joel P. Conte), the Xiamen University, China (Associate Prof. Quan Gu), and the University of California Davis (Prof. Michele Barbato)

Manual for Sensitivity Analysis

The manual for sensitivity analysis provides the commands available to perform finite element response sensitivity analysis based on the Direct Differentiation Method using OpenSees.

Application Examples

The following folders contain the input files for the application examples described in the manual and used to validate the finite element response sensitivity analysis objects implemented into OpenSees. Matlab files are also provided to visualize the results obtained:

• Example 1: 2D Soil
• Example 2: 3D Soil
• Example 3: 2D Frame
• Example 4: 3D Frame
