STKO for OpenSees

STKO | Scientific ToolKit for OpenSees |


STKO (Scientific ToolKit for OpenSees) is an OpenSees Graphical User Interface (GUI) with a powerful pre and postprocessor. It is a cutting-edge data visualization tool, which provides users with an intuitive interface for navigating the OpenSees environment. Using STKO, a user can create a Tool Command Language (TCL) input file for OpenSees and an output file readable by its graphic interface. The user can customize and manipulate the model input and output with a Python-based scripting interface to create customized engineering demand parameters and output data.
