Checkbot for Tekla Structures

Project name: 
Checkbot for Tekla Structures
Project category: 
IDEA StatiCa
Project location: 
Czech Republic


Checkbot for Tekla Structures is an application for automated steel connection design as per AISC, Eurocode, and other standards.

Using Checkbot, engineers and detailers can select any number of connections in Tekla Structures, load them and code-check them in one go.

Clear pass/fail checks for all the connections are available immediately.

Problem that app solves

Checkbot provides a quick way of making sure the connections in your Tekla Structures model are safe and code-compliant. You can also use it to effectively identify the parts of the structure that can be optimized.

The calculation itself is done using a scalable set of cloud servers to handle simple as well as a robust set of connections. Checkbot enables engineers and detailers to move from a one-by-one connection design approach to working with groups and bulks of connections.


Checkbot is the response to the strong community call for the better and automated structural design of steel connections inside Tekla Structures.

Checkbot will be available in Private BETA in October 2020 and will go into Public BETA in April 2021.

Development project

Checkbot for Tekla Structures represents a paradigm shift in connection design – it moves the laborious data process from desktop to scalable cloud. Checkbot brings the possibility of massive productivity gains for structural engineers and detailers involved in the design process.

Development of the Checkbot has been an exciting task and valuable learning experience for our development team. There were 3 persons directly involved and 20 in total.

About the company - IDEA StatiCa

We develop software for structural engineers and detailers. Our development team researches, tests, and applies new methods of analyzing the behavior of structures and their members. Based on this, we create IDEA StatiCa – software that enables engineers to work faster, evaluate requirements of the national code thoroughly, and use the optimal amount of material. For us, creating software is a way to contribute to making every new construction around the world safer and cheaper.

We have worked with Tekla Structures and its APIs since 2015. The Checkbot is a result of building on this experience, enabling effective workflows for Tekla Structures and IDEA StatiCa users.

Here the functionality of the IDEA StatiCa  Viewer app has been expanded to present detailed results  of Checkbot for Tekla Structures.Checkbot can be used on any Tekla Structures model with detailed connections.Checkbot automatically integrates into the Tekla Structures ribbon.Checkbot creates individual connection files and saves them with the Tekla Structures project.Imported connections can be reviewed in the interactive scene.Simplified loads are specified as a percentage of member's resistance.Summary results of code-checks (for plates, bolts, and welds) are displayed for each connection.Detailed geometry can be reviewed using our IDEA StatiCa Viewer app, called directly from Checkbot for Tekla Structures.
