Steel Design

EC3 steel design can both check and auto design your steel members.

Everything is presented like hand-calculations to make sure, that this is not a 'black box'.

National annexes handled are Danish, Finnish, German, Hungarian, Norwegian, Polish, Rumanian, Swedish and British.The Steel Design module handles bars and shells in ULS, SLS and fire. It takes you through all Eurocode checks. Steel Design also has the 'clean' Eurocode without national annexes.

 

Steel Joints Design

FEM-Design checks and designs steel joint according to EN 1993-1-2. Steel Joint is a separate module that is available in two versions: standalone or built in FEM-Design 3D Structure.

Characteristics

  • Total of 51 solutions and 7 types (according to the Swedish Institute of Steel Construction).
  • Use predefined solutions and design the connection using bolt and/or welds.
  • Define the load and steel sections in the stand-alone version, or get automatic import of the geometry and load combination results from FEM-Design 3D model.
  • Easy and clear overview of the result and utilizations.
  • Save your solution in a collection for future use.
  • Get a documentation of both drawings, but also welds and bolts needed.

Steel Joint Stiffness

FEM-Design gives the opportunity to set the rotation stiffness of Steel Joints automatically or manually, and apply it to the structure. The rotational stiffness of semi-rigid joints connecting H and I profiles can be calculated automatically according to methods given in EN 1993-1-8.

Documentation

FEM-Design automatically generates documentation for each joint that contains the input data of the joint (Member data, Load combinations, data of all components) and detailed calculations, so called detailed result.

This is not a black box. All design calculations are presented like hand calculations. Easy to follow:

 

Convert your bar element into shells with one click. Add holes etc. Follow the design calculations and create your structural report. Easy.

 

Steel Fire Design

FEM-Design checks and designs steel bars for fire effects according to EN 1993-1-2 for nominal fire curves.

Design options

Steel members can be verified and designed for fire effects based on (among other parameters) the fire duration, fire curve and section exposure. FEM-Design allows for auto-design and manual design of steel members.

Auto design

Manual Design

There are two manual design options:

  • Design for fire protection material (from library or user defined)
  • Calculate maximum temperature

 

Steel fire design: Auto Design options

There are two manual design options:

  • Apply chosen fire protection material (from library or user defined)
  • Set maximum member temperature

Detailed results and documentation

It is possible to display detailed calculation report for each steel bar, for both protected and unprotected members, for auto- and manual design. That report can be added to documentation module, or exported to .docx or Mathcad format.

Steel fire design: Detailed results

In Documentation module, one can display utlization tables containing crucial information regarding fire duration, applied insulation and utilization before fire and at fire conditions.
