IDEA Connections  - Structural Software for the design of steel connections

IDEA Connection enables engineers to design steel joints of general shape, connections and base plates with no limitation in shape and loading. It is based on a unique design and analysis method called CBFEM. It delivers precise checks of each component of the joint.


IDEA Connection enables engineers to understand and minimize risk of construction defects. It removes uncertainty in connection design to decrease material costs by up to 30%.

Key features of IDEA Connection

  • Structural design and check of joints, connections and details of steel structures
  • Joints with various numbers of beams in multiple directions and loads
  • Analysis model created according to manufacturing operations used – cuts, plates, stiffeners, ribs, openings
  • Calculation of internal stress/forces in joints based on elastic/plastic FEA analysis
  • Automatic creation of joint’s FEA model
  • Efficient FEA solver delivers result faster than current methods
  • National-code-independent solution; design checks according to EN 1993-1-1
  • Checks of bolts and welds using standard component method
  • Graphical presentation of shape of the joint to check member collisions
  • Clear information about behavior of the joint/connection
  • Both simple (1 connection = 1 A4) and detailed result reports
  • Wide range of predefined joint/connection templates; user defined templates

BIM – link with the structural software

IDEA Connection can be used as a standalone program - input of geometry, loads and all operations is done manually. But IDEA Connection also supports BIM - steel joins including loads (internal forces) can be imported from several FEA programs, for example MIDAS Civil and GEN, AxisVM, SCIA Engineer and Nexis (Esa Prima Win).

Design and check

IDEA Connection runs proper checks according to EN 1993-1-8. Steel plates are check against the requirement of maximal equivalent strain. Bolts and fasteners are checked both on normal and shear force like separate components. Stress in each weld is properly evaluated and weld is checked. Interaction of base plate and concrete block is analyzed – effective stress is checked.

Working with data model from another 3D structural FEA program. Interface for data import from external FEA programs. 1D and 2D members – beams, columns, slabs, walls. Assigning members into design groups. Check results including structures from different materials. Updating model back to FEA program after proper designing of members. Updating designed members after change in FEA program.
Each engineering office has several programs to deal with different tasks of engineering practice. Outputs of one program are often inputs of the other and vice versa. That is why we developed a unique IDEA BIM (building information modelling) interface which connects IDEA StatiCa with other programs in an easy and effective way.
IDEA BIM enables engineers to get inputs from their current software – it instantly transfers model of internal forces to IDEA StatiCa where required members/details can be designed. Some of IDEA BIM links are also two-way, i.e. transferring results from IDEA StatiCa back to FEA program.
