The PSE software allows to verify, design and optimize the steel members of a structure.

• Calculation of the bending, compression, tension, shear and combined resistance of steel elements.

• The program optimizes the section shapes to minimize the weight or the cost of the whole or a part of the structure. This optimization is performed based on the complete or customized list of standard section shapes or any user defined library of standard and parametric sections shapes.
• Geometrical limits can be defined to control the dimensions and properties of the section shapes selected by the optimization engine.
• The optimization engine can check various deflection criterions during the section selection process.


The latest revision of the PSE software enables structural steel designers to design cold-formed steel members based on the North American specification for the design of cold-formed steel structural members covering Canada (CSA S136-16), the United States and Mexico (AISI S100-16). Cold-formed steel sections can be mixed with regular steel shapes in a model allowing to design ​hybrid structures.

Supported section shapes:
•60° and 90° angles and 90° angles with lips
•Channel with or without lips
•Z sections with or without lips
•U (Hat) sections

​ Performed design checks:
•Tension resistance (Chapter D)
•Compression resistance including distortional buckling (Chapter E)
•Bending resistance including distortional buckling (Chapter F)
•Shear resistance (Chapter G)
•Combined forces (Chapter H)
•Web yielding and web crippling at supports (Chapter G)

Design of steel sections and cold formed steel sections.
Standard CISC, AISC or European sections or parametric section shapes (over 25 shapes available).
All parameters required to calculate the resistance of the elements such as unbraced length, buckling lengths, buckling factors and others can be customized either graphically or from spreadsheets.
Latest revisions of CAN/CSA S16, AISC, ASD and LRFD, Eurocode 3 and 4 standards and Indian IS 800-2017.
Latest revisions of CSA S136 and AISI S100.
Singly symmetric, asymmetric and built-up section shapes are covered for all design codes.
Limit states design of the optimized structure are presented in colors.
Steel verification includes sections classification, resistance and stability checks according to the applicable code.
Calculation of the bending, compression, tension, shear and combined resistance of steel and composite elements based on the results of a linear, P Delta, non-linear, seismic, dynamic or moving load analysis.
The design of composite beams accounts for long term deflections, partial composite action, plain slab or slab cast on standard or user defined steel decks and user defined studs.
The slab reinforcement can be considered in the calculation of the elements resistance.
It is possible to consider the analysis of composite beams with the full composite inertia or the effective inertia in positive moment regions or the steel beam inertia in negative moment regions.
Complete check of deflection according to a comprehensive set of criterions.

The STEEL CALCULATOR™ is a complementary application of the PSE software.

The STEEL CALCULATOR™ allows to quickly verify, design and optimize steel beams and columns. It is also an efficient validation tool to verify design results of specific elements of complex models.

Design optimization and automatic section selection features make economic and quality steel structures a reality.

The STEEL CALCULATOR™ allows the user to verify and optimize single and continuous beams and columns. The use of the Steel Calculator does not necessitate the input of an analysis model (joints, members and combined loads). These operations are automated.

The  STEEL CALCULATOR™ allows to verify or optimize any standard section available in the software databases according to the Canadian S16 standards, the American LRFD and ASD standards and the European Eurocode 3 and the Indian IS 800.

KEY features

The PSE is a structural engineering software solution for the analysis, design and rehabilitation of drilling structures including drilling masts, derricks and substructures.

The advanced structural analysis of the PSE software allows engineers to achieve specialized analyses crucial to offshore and onshore projects related to the oil and gas industry.

Wind loads, based on the velocity component approach, are defined according to API 4F Specification for Drilling and Well Servicing Structures (5th edition).

Vessel dynamic motions are defined according to API 4F Specification for Drilling and Well Servicing Structures (5th edition).

Other environmental forces such as wave and current loads are also considered for the analysis and design of offshore drilling structures.

The PSE software allows to verify, design and optimize steel members of drilling structures according to various international design codes.
