STEELexpress                    Design of Stuctural Steelwork Elements according to Eurocode 3 EN 1993:2005
With STEELexpress you can easily design structural elements of structural steel.
Classification of cross-sections, Resistance of cross-sections in single and combined actions, Flexural and lateral buckling resistance of members. Design of connections. Design of beams, columns, roof and floor structures. Design one floor frames and two floor frames. Design of purlins and bracing systems. Design of footings of steel structures.Design of composite steel and concrete structures, according to Eurocode 4. Parameters according to National Annex of Eurocode. Detailed reports with references to Eurocode paragraphs and necessary drawings. Tables with all international steel profiles with dimensions, resistance and buckling resistance values. User defined steel section properties. Welded steel sections formed by the user.
A combined detailed report  is produced for the designed steel components. Assumptions and references to design codes are shown in the report. The user can select the applicable National Annex. The design code parameters, as well as default values, can be adjusted by the user. Design Charts and Tables for use and understanding of Eurocode 3 are included in the program. For frame structures the program's CAD modulus automatic generates detailed drawings of the structure and the joints.

  Design of steel frames

Single bay portal frames under vertical and horizontal loadings, also with concentrated loads on the columns.

Single bay portal frames under snow, wind and seismic loading.

Two floor frames under vertical and horizontal loadings.

  Design of Steel Beams

Single beams
(simply supported, fixed in one end or fixed in both ends). Combination of uniform, triangular or concentrated loads. Various lateral length supports.
Floor beams of one or two spans or one span and cantilever. Laterally unrestrained, restrained at one or two intermediate points, or totally restrained.
Roof beams of one or two spans. Snow, wind pressure and under pressure, imposed load.
Purlin design. Simply supported or continuous. Laterally restrained or unrestrained.


  Design of Steel columns

Single members in compression (various end conditions  and buckling lengths).

Columns under axial load, or axial load and single or double  bending.

Columns in simple constructions (simple columns, columns in braced or unbraced frames).

  Design of bolted connections

Design of various connections according to Eurocode 3-1-8

Connections are design for specific actions, and the program selects the optimum connection geometry and bolt number and arragenment .

You may also specify the bolt number and configuration and the program computes the connection capacity.

Tension connections
Shear joint
Double shear joint
plice joint

Short continuity of I section
Beam to beam connections
Beam-continuation connection
Gerber-beam connection
Beam-on-beam connection with web cleats
Beam to column connections
Beam on column connection with web cleats
Beam on column connection with end plates

Connections of portal frames 
Bolted connections with end or base plate. 

Apex connection
Eve connection with
Eve connection without haunch
Simple column base connection

Fixed column base connection


Connections made with pins
Pin ended member
Gerber-beam connection
  Design of Bracing systems

Bracing systems are required to resist transverse actions, due to wind and earthquake.

Vertical bracing system in the sidewalls between the columns.
This system transmits the horizontal transverse loads from the roof to the ground and temporary stability during the erection.

Horizontal roof bracing system
On the roof to transmit the transverse loads from the roof to the vertical bracing and to provide temporary stability during the erection.

 Design of footings of steel structures

Pinned footing under vertical and horizontal loading

Fixed footing under vertical and horizontal loading and moment

Footings resisting horizontal forces only with passive earth pressure

Footings with horizontal ties in order to resist horizontal forces

 Design of base anchoring system

Simple base connection  (vertical and horizontal forces).
Fixed base connection. (vertical , horizontal forces and overturning moment).

Anchor bolts with hooks or with washer plates.

  Eurocode 4

Design of composite steel and concrete structures

EN 1994-1-1:2004 Design of composite steel and concrete structures, General rules and rules for buildings


 Resistance of cross-sections
Design of steel cross section in Ultimate Limit State (ULS) for various combinations of actions.
For a selected cross section and the actions on the cross section the design the design resistance of the cross section is computed. 

Single actions
Tension Nt
Compression Nc

Double actions
Bending and compression Nc-Myy
Biaxial bending Myy-Mzz

Compression and shear Nc-Vz

Steel sections

Standard sections, user defined, welded sections
Dimensions, geometric properties
Resistance values (axial load, bending shear)
Buckling resistance and lateral buckling resistance for various buckling lengths
Tables of all the international steel profiles

Dimensions, properties, classification resistance values for various actions, buckling and lateral buckling resistance values.

Tables of non-standard steel sections
Section properties are defined from the user.

Tables with welded (fabricated) steel sections
The user can make the steel section by giving the dimensions and thicknesses. The geometric and strength properties are computed by the program. These sections can be used anywhere in the program for designing steelwork elements.
