The PSE 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.

The software allows the user to create load combinations. A load combination results in an algebric combination of distinct basic loads. Each basic load is multiplied by a load factor. The resulting load combination acts on the structure to generate a specific structural response.
The load combination wizard in the program also allows creating load patterns.

The load combination wizard generates load combinations according to NBCC, UBC, ASCE 7, BOCA, Eurocode and ECC.

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.

In the interface of the PSE, the user can create a catenary cable by associating a cable type section to a member.

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.

This option is available for AISC 360-16 and AISC 360-10 standards.

The options for the Stability Design Method are Direct Analysis Method (DAM) and Effective Length Method (kL).

Functionalities of the PSE program allow to generate automatically detail elements in an automatically generated mesh perimeter.

These functionalities are specifically  related to the refinement area, the opening, the linear constraint and the punctual constraint. All detail elements added to the PSE model will be automatically connected to the finite element mesh.

The mesh perimeter will also connect any elements already in the model to the mesh perimeter automatically if they are in the plane of the mesh contour.

Functionalities of the PSE program allow to display objects transparency for various components such as current selection, solid members, plates, surfaces, spatial objects, panels.

The level of transparency may be customized for each type of object from the Display Options command.


The integration of IFC in the PSE program enables importation of models from a large number of architectural and structural software.

IFC (Industry Foundation Classes) is an open and neutral data format allowing the definition of related classes to all construction objects. It is dedicated to the building sector and aims to software interoperability (all editors, all applications).

IFC is the most widely used protocol for information exchange and sharing between different platforms of BIM (Building Information Modeling).
