About IDEA StatiCa

We develop software for structural engineers and detailers. Our development team researches, tests, and applies new methods of analyzing the behaviour of structures and their members. Based on this, we created 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.

Release notes IDEA StatiCa Steel 20.1

The new version of IDEA StatiCa is here! Whether you are using IDEA StatiCa as a standalone app or via BIM links with FEA/CAD applications, the version 20.1 will speed up your connection design dramatically.

We have put much of our focus on allowing engineers to evaluate the requirements of the national code so that they can use an optimal amount of material. 

Highlights of this version are:

Cost estimation – calculate how much the connection will cost, real-time in the 3D scene, based on your fabrication data.

Pre-design – The IDEA StatiCa engine proactively models parts of connections for you, speeding up the process of fine-tuning your designs into the absolute best.

Bulk selection of connections from Tekla, Advance Steel, Revit is now possible  –  no more selecting connections one-by-one in 3 different steps. Simply drag over 10 connections in Tekla and IDEA StatiCa will export them automatically. Some changes in Tekla? Just click “Sync all”.

Additionally, we are happy to announce improvements to our IDEA StatiCa licensing, these have been implemented in order to remove any inconveniences found by users since the recent update in the spring. 

We hope you will enjoy all our new features and improvements and would love to hear your feedback anytime. 

Cost estimation

IDEA StatiCa Connection v20.1 introduces a feature that can calculate connection production costs while in the 3D scene. Users can now instantly estimate the final price of the created design and optimize the connection of concern.

Prices of individual connection components can be specified on a cost per unit weight basis in Settings. Costs can be defined for four basic entities:

  • Steel parts (plates and added steel members, grade dependent)
  • Welds (single and double fillet welds, ½ V and K butt welds, weld size dependent)
  • Bolt assemblies (grade and diameter dependent)
  • Hole drilling (as a percentage of bolt assembly cost)


The resulting value is presented in the 3D scene and is updated according to manufacturing operations used in the design. Detailed cost calculation is an optional part of the calculation report.

Pre-design is a new feature intended to provide a sensible starting point and shorten the connection design process. The feature is in its early stage and was primarily implemented for I-shaped cross-sections and these most common manufacturing operations:

  • Fin plate
  • Splice
  • Shear endplate
  • Flush and extended endplate
  • Welds

How does it work?

Pre-design reads input data from the properties table of the given manufacturing operation and then creates a suggested initial design. In general, material and geometrical data of the connected members, bolt assembly, and weld data are all read as inputs for the process of pre-design. As a result (output), plate thickness, weld sizes, number, and layout of bolts are generated.


The resulting design is roughly based on the resistance of the connected cross-sections or plates. The percentage of this resistance can be modified in pre-design settings (top ribbon). A higher percentage will yield more robust designs.


There are several other preferences you can change in Settings, including preferred dimension increments for plate thicknesses, weld size, and bolt spacing.

In case a given operation is supported, you can call on pre-design by right-clicking the operation name in the tree of operations, or by clicking the button in the orange tab at the top of the operation property grid. Pre-design is also called automatically on creating a new operation. It is also possible to get the pre-design in batch for all supported operations just by right-click on Operations in the tree.

Settings dialogue

The new version further enhanced with a new button in the top ribbon that opens the Settings dialog. In this dialog, two main new features of 20.1 can be adjusted: Cost estimation calculation and connection Pre-design.

The Settings dialogue comes with a template functionality that allows saving the input values in a template, loading values from different templates, and selecting a default template for new projects. The templates are specific to different features and are code specific as well.

New Connection Wizard

The new version comes with better sorting of the starting Topology templates. You will find the open sections like I or L-shapes at the top, followed by the rectangular hollow sections topologies, and circular hollow sections at the end of the library.


In the Design section of the wizard, the proposed variants are grouped based on the expected behavior of the connection: Moment connections, Shear connections, and Truss connections. Of course, the option to start with a blank project is preserved as well.  


All this will help you to speed up the template selection process and improve awareness of the connection properties.

Percentage loading

A new and simple option on setting the load effects was added into IDEA StatiCa Connection 20.1. The members can now be loaded by a defined percentage of the capacity of its cross-section. The setting of loads as a percentage of cross-section capacity is meant mainly as a simple tool. Setting loads in equilibrium is preferred.


The cross-sectional properties can be viewed in the Materials tab. Torsion is disabled because the member resistance in torsion cannot be clearly determined due to unknown warping constraints.

Bolt bearing distances for Eurocode

The new version brings an improved algorithm for calculating the bolt spacing (p1p2), end (e1), and edge (e2distances for the Eurocode bearing check. This improvement is mostly relevant for general plate geometries, plates with openings, cutouts, etc.


The algorithm reads the real direction of the resulting shear force vector in a given bolt and then calculates the distances needed for the bearing check.


The end (e1) and edge (e2) distances are determined by dividing the plate contour into three segments. The end segment is indicated by a 60° range in the direction of the force vector. The edge segments are defined by two 65° ranges perpendicular to the force vector. The shortest distance from a bolt to a relevant segment is then taken as an end, or an edge distance.


The spacing distances between bolt holes (p1p2) are determined by virtually enlarging the surrounding bolt holes by a half of their diameter, then drawing two lines in direction and perpendicular to the shear force vector. The distances to the enlarged bolt holes that are intersected by these lines are then considered as p1 and p2 in the calculation.

An improved model of contacts

The analysis model contains several nonlinearities, among them contacts between plates. The contacts are very strong in compression and extremely weak in tension. However, some stiffness is necessary even in tension to ensure the numerical stability of the model. There were several very rare cases with a large contact area and a large deformation in tension where the tension in contacts consumed a significant portion of set loading. 

IDEA StatiCa UK - Improved model of Contacts

The contact model was improved to maintain the stability of the numerical analysis and limit tensile force in contact to a negligible level.

Check of missing welds

We have added another useful tool to automatically help the user to find non-welded parts of the connection: the utility to analyze a connection model for potentially missing welds. 

The tool identifies and lists the relevant plates and plate edges and allows the missing welds to be added. You can enter this functionality by the right-mouse click on Operations in the tree of entities on the right side of the scene.

Versions of applications supported by IDEA StatiCa 20.1 (Steel)

Bulk Selection

The Code-check manager (CCM) was improved by the possibility to select multiple joints of the global model in one go. 


This is feature is available for both CAD and FEA applications. In CAD apps, you will find a new button while in FEA apps, this feature works by selecting multiple joints in the global model and selecting the Connection/Member button in CCM.

Export of recommended welds

When importing a connection from CAD software, there is now an option to add recommended welds. When selected, a check for potentially missing welds is performed. Such welds are then added and imported along with the rest of the components. These welds might be missing due to an incorrect import, or perhaps they are not in the CAD model altogether. The added welds are then labeled as “recommended weld” in the tree of operations in IDEA StatiCa Connection.

Licensing improvements highlights:


  • Possibility of the automatic sign out after you close IDEA StatiCa 
  • IDEA StatiCa launches 40% faster   
  • Better error messages so you know what the problem with your license is  
  • New License dialog with “Forgotten password” button at hand 
Licensing dialog box in 20.1 version

IDEA StatiCa 20.1 has a new License dialog:

“Keep me signed in” Check box

This new checkbox defines if you want to use the offline activation window or not. Are you and your colleagues online all the time and want to share the license quickly? Or do you want an option to leave the office and finish your work on the road without an Internet connection? You can do both with the new licensing of IDEA StatiCa.


If “Keep me signed” is checked, IDEA StatiCa behaves as in version 20.0 – after closing the program, the license stays on your computer for 72 hours without the need to be connected to the Internet. And nobody else can access it.  You might switch your PC off and on during this time. This is useful for work trips, home office, or workplaces with an unstable Internet connection.


If this checkbox is empty, the license seat will be returned to the license pool immediately after you close IDEA StatiCa. The offline window is not activated, and other users in your organization can get your license immediately. However, this requires a constant connection to the Internet. This is useful for bigger groups of engineers with a stable Internet connection.

Remember me

If checked, IDEA StatiCa will remember and prefill your username and password in the license dialog for faster Sign In.

Forgot password?

All the engineers in the organization can quickly recover their password using the “Forgot password” button. If you do not have an account and your organization has an IDEA StatiCa license, you need to ask your Administrator to add you as a licensed user.


No license yet in your company? You can quickly get a trial using the FREE trial button.

Faster Startup, better messages

The initial start of IDEA StatiCa is now 40% faster due to the improved authentication sequence. Changes in products and license updates are faster by 70%. We have also made the error messages clearer – for example, a new clear message when all the seats of IDEA StatiCa in your organization are taken by somebody else.
