Efficiency check for steel structural members.

The steel beam design module can be applied to the following shapes: Rolled I shapes, Welded I shapes, Box shapes, Pipe shapes, Single-symmetric I shapes, Tee shapes, Rectangular (solid) shapes, Round (solid) shapes, Arbitrary shapes, some checks are not performed.

Among elements with cross-section class 4, single- and double-symmetric I shaped, rectangular and box shaped cross-sections can be designed with this module. Effective section properties are calculated in the cases of uniform compression and uniform bending.

Available for:

For the design based on Eurocode 3, the following design parameters should be defined and assigned to the structural members:

AxisVM calculates the moment-curvature diagram, the resistance moment and initial strength of steel column-beam bolted joints based on Eurocode3 (Part 1.8 Design of Joints).

The above type of joints can be calculated: - beam to column joint and beam to beam joint

Assumptions:

•   The beam and column cross-sections are rolled or welded I shapes.

•   The beam end plate connect to the flange of the column.

•   The pitch range of the beam is beetwen ± 30°.

•   The cross-section class should be 1, 2 or 3.

•   The normal force in the beam should be less than 0.05* Npl,Rd.

The program checks if these requirements are met.

The calculation method considers shear forces and normal forces together with the moments. As a consequence we can get different resistant moments (MrD) for the same connection depending on the load cases (or combinations).

Therefore AxisVM checks the MrD, MsD condition in all load cases.
