STKO
STKO, the Scientific ToolKit for OpenSees, is the earthquake engineering software developed by ASDEA Software Technology for structural and geotechnical analysis. It allows engineers, researchers and students to create, analyze and visualize complex models without writing TCL scripts manually.
Features
-
Pre-processor
Models are built and validated from the graphical interface, ready for OpenSees.
-
Post-processor
Simulation results are interpreted visually.
-
Structural analysis
Simulations of complex structures.
-
Geotechnical analysis
Geotechnical models in the same environment as the structures.
-
Earthquake engineering
Software built for earthquake engineering.
-
Soil-structure interaction
Structure and soil simulated together, in a single model.
Advantages
Complete for OpenSees
A complete pre-processor and post-processor for OpenSees.
From concept to result
With STKO you visually build, validate, run and interpret simulations.
No scripting
No TCL scripts to write by hand.
STKO PRO
STKO PRO is the version of STKO built for engineering practice. Based on the proven STKO/OpenSees nonlinear foundation, it brings advanced analysis into professional workflows. STKO PRO is a dedicated product, separate from STKO, offered with an annual professional license.
Features
-
Nonlinear analyses
Pushover, response-history analysis, modal analysis and response spectrum.
-
Linear static
Available alongside nonlinear analysis.
-
Performance verification
Performance-Based Design (PBD) workflows.
-
Repeatable workflows
Loads, constraints, analysis presets and model definition are organized into repeatable workflows.
-
Curated component library
Tested, recognized and documented components for modeling decisions that can stand up to review.
-
AI assistance (MCP)
AI assistance works inside the model: every action stays visible.
Advantages
Nonlinear first
Most structural software starts from linear analysis and adds nonlinear capabilities later as an advanced option; STKO PRO takes the opposite approach.
Clearer deliverables
Advanced analysis leads to clearer project deliverables.
The engineer in command
The engineer stays in command.
Bridge Sense
Bridge Sense is the web platform for 3D visualization and traffic evaluation on bridges. It brings together the bridges of a road network on a map, along with toll gates and intersections.
Features
-
Vehicles, axles and loads
Each vehicle is defined with its axles, loads and spacings.
-
Routes and lanes
On the map you pick a route between a start and an end point and the traffic lanes to follow.
-
Simulations with STKO and OpenSees
Simulations on every bridge along the route, with load amplification factors.
-
Results in 3D
Results on each bridge model, with the internal force diagrams.
-
D/C ratio
Demand/capacity ratio and most critical combination per lane.
-
Dynamic coefficient
Applied to speeds above 30 km/h.
-
Word report
Report with charts and images.
Advantages
An archive for every bridge
For each bridge it collects the structural model developed with STKO and OpenSees, the documents and the technical notes.
Real time
Simulation progress is tracked in real time.
Custom capacities
Capacities can be overridden where specific checks are needed.
MonStr True Vision
MonStr True Vision is the web dashboard for structural health monitoring. It runs on the acquisition PC installed on site, where data are collected, stored and processed locally.
Features
-
Datalogger and sensor status
From the dashboard you control the whole installation, from the status of dataloggers and sensors to the signals.
-
Real-time signals
Sensor signals are followed in real time.
-
Acquisition archive
You scroll through the recording timeline and check the recording quality.
-
Sensor and axis comparison
Several sensors, devices and axes on the same chart.
-
Operational Modal Analysis
Natural frequencies, damping ratios and mode shapes, animated on a model of the structure.
-
Offline site map
The site map stays available even without internet.
-
HDF5 data
Data ready for STKO.
-
Cloud access
With a single login you enter from one address in the browser and switch between systems in the same window.
Advantages
Works offline
The system keeps working even without an internet connection.
Encrypted link
Installations are reached through a VPN.
Each customer, their installations
Each customer only sees their own installations, while the data stay on the on-site PC.
SHM tool suite
The SHM tool suite brings together the software ASDEA has developed for structural health monitoring.
Features
-
OSP
Optimal Sensor Placement (OSP) starts from the numerical model of the structure and indicates how many sensors to install and where, to collect more information with fewer devices.
-
Data processing
The processing tools clean and select the signals recorded by MonStr sensors, discard noisy or irrelevant recordings and prepare the data for structural identification.
-
OMA
Operational Modal Analysis (OMA) identifies the vibration modes and frequencies of a structure from the vibrations measured during normal operation. The modal parameters calibrate the numerical models developed in STKO.
-
Damage Detection
MonStr AI combines data-driven and model-based methods to detect anomalies and damage and predict the behavior of the structure. The digital twin in STKO verifies the anomalies and rules out false alarms.
Advantages
Developed in-house
Like the MonStr sensors, every tool is developed in-house and works on the same data format.
One environment
Data-driven algorithms and model-based tools are managed in the same virtual environment provided by STKO, initially designed for finite-element analysis and now extended for sophisticated digital twinning applications.
Big data and parallel computing
Parallel computing, GPU programming, big data analysis, cloud computing and real-time charts.
Anywhere
Data can be visualized anywhere, at any time.
