CORE FEATURES
Core analysis workflow
STKO provides a complete and integrated environment
for nonlinear structural analysis, covering the entire
workflow from model definition to result interpretation.
PRE-PROCESSING
Model complex structures
with full control
STKO provides a powerful pre-processing environment
for building detailed structural models. Geometry, materials,
constraints, loads, and boundary conditions are defined
explicitly, ensuring clarity and consistency with
OpenSees formulations.
Explicit definition of nonlinear elements
Consistent material modeling
Clear and inspectable model setup
Post-PROCESSING
Advanced result visualization
and interpretation
STKO offers advanced post-processing tools to explore, interpret,
and validate analysis results. Stress maps, deformation shapes,
and time-history responses help engineers gain insight
into complex nonlinear behavior.
Visual interpretation of nonlinear response
Time-history analysis exploration
Model verification and validation
HDF5 DATABASE & MPCO RECORDER
Efficient result storage
and data management
STKO integrates an HDF5-based database and the MPCO Recorder
to store OpenSees results efficiently. This approach enables fast
access, structured data organization, and consistent
post-processing even for large-scale analyses.
Scalable result storage
Fast data access for large models
Reliable post-processing workflows
PYTHON SCRIPTING
Workflow automation
and customization
Python scripting in STKO allows users to automate repetitive tasks,
customize modeling procedures, and integrate STKO into
research or professional workflows.
