## ACHIEVE FINITE ELEMENTS ANALYSIS (FEA)

## PERFORM CATENARY CABLES ANALYSIS*

The catenary cable element is a highly non-linear element used to model the catenary behavior of a cable suspended between two points under the effect of its self-weight. This formulation accounts for the non-linearity due to large displacements. A cable has no bending, shear, compression or torsion stiffness. Due to this fact, the fixities at the ends are ignored, the cable is always treated as member acting in tension only.

## SPATIAL OBJECTS AND SPATIAL LOADS*

Spatial objects are used to model non-structural secondary elements attached to the structure. These elements add no stiffness to the existing model. Loads applied to spatial objects are transferred to the structure through one or more attach joints. The loads are transferred using a "rigid plate" approach.

Concentrated, pressure and wind loads may be applied to spatial objects. The figures below shows a spatial object loaded vertically and horizontally attached to a cantilever column. Also, it shows the deformations and biaxial moments induced by the loads transferred by the spatial object.

## CONSIDER TORSION AND WARPING

The software considers restrained warping for the torsion of thin-wall open sections. Notice that this phenomenon is not included in most commonly used frame analysis programs. Almost all frame programs in practice use St-Venant torsion theory ignoring the effects of restrained warping.

It is important to note that the torsional stiffness of an open section is function of the warping end conditions as well as the location of the torsional load. Thus, the distribution of the forces in the structure having members resisting torsion may differ whether this option is enabled or disabled. A subdivided continuous member needs to be specified as a physical member to get the continuity effect of warping along the member.

In addition to shear stresses, some members carry torque by axial stresses. This is called warping torsion. This happens when the cross-section wants to warp, i.e., displace axially, but is prevented from doing so during twisting of the beam. In other words, the section tends to resist torsion by out of plane bending of the flanges.

## PROFIT FROM BUILT-UP SECTIONS

The program allows defining built-up sections whose properties are calculated by the means of a finite element model. Various shapes are supported.
