Advance Design Connection is a unique version of IDEA StatiCa Connection, rebranded and tailor-made for GRAITEC users. It is fully integrated to GRAITEC Advance Design.
Advance Design Connection can design all types of welded or bolted connections, base plates, footing and anchoring. It provides precise checks, results of strength, stiffness and buckling analysis of a steel joint. Joints are checked according to EC/AISC. Templates for most-used connections are available as well as wide range of predefined hot rolled and sheet welded members.
No limits in how many connections there are in the joint and how they are put together. Shape is defined by project requirements, not by software capabilities.
All forces are analyzed. The overall check of the joint takes into account interactions between all the beams and connections. Engineers stay on the safe side all the time.
The whole design and check process is kept short enough to be a part of everyday work of structural engineers and fabricators all around the world.
Design your joint from scratch or build on geometry and loading imported from GRAITEC Advance Design, Robot, Revit. More BIM Links will be added in the future.
Take advantage of integration into Advance Steel to provide workshops drawings and support manufacturing process
According to various national design codes
FE model of steel joint is composed automatically
Rotational or transversal stiffness of any connection
Seismic check of non-dissipative connections
Local buckling effects and critical load factors
Maximal possible loads, reserve in joint capacity
Advance Design Connection can design steel joints and connections of any topology and loaded in all directions. It keeps the whole analysis-design-check process in minutes. This opens a possibility for structural engineers and fabricators around the world to increase productivity of designing steel joints and connections.
Stay on the safe-side with all checks according to selected national codes at hand at any time.
Engineers spend 70% of the connection design time on 30% non-standard cases. Do them in minutes as well.
Know exactly how much material is needed in the joint and take advantage of it.
You can choose from three types of output reports – one line, 1 page and detailed. All checks according to Eurocode or AISC are displayed and referenced.
Base plate – N, My, Mz
3D loaded joint
End plate – My, Mz, Vy, Vz
Steel joint is composed from plates, welds, bolts, contacts and can be anchored into concrete block. FEA model is generated automatically.
Model is composed from steel plates – both parts of steel members and stiffening plates. Real shape of plates is kept.
Each plate is meshed independently. Equivalent strain is checked.
Contacts appear in places where two plates are in touch. They take 100% of the pressure but do not act in tension at all.
Steel structure can be anchored into concrete block. Base plate is in contact with concrete. Tension is taken by anchors, shear by bolts, friction or shear iron.
Welds are modeled as constrains between plates. Forces in each weld are evaluated. Stress in weld is checked according EN/AISC.
Bolts are nonlinear springs taking tension and shear.
Together with two top technical universities, we created a new method for analysis and check of steel joints of general shapes and loading. It is called Component-Based Finite element model (CBFEM). After 5 years of primary research and theoretical preparations, the first version of the application was coded in 24 months and released in May 2014.
We combine two well-known and trusted methods used by engineers all around the world – finite element method and component method:
Joint is divided into components
All steel plates are modeled by finite element method assuming ideal elastic-plastic material
Bolts, welds and concrete blocks are modeled as nonlinear springs
Finite element model is used for analyzing internal forces in each of the components
Plates are checked for limit plastic strain – 5% acc. to EC3
Each component is checked according to specific formulas defined by the national code, similarly as when using component method
Results of all tests performed to confirm safety and reliability of CBFEM method and Advance Design Connection are published and available. Visit our website to examine them. Professor Wald and his team are also publishing a book devoted to structural steel connections design using CBFEM method:
