CSC Orion is structural engineering software for the design of reinforced concrete and steel structures, now a part of the Tekla product portfolio, which also offers solutions for the rental, IT, and legal industries. It enables engineers to design buildings with physical objects like beams and slabs, automate analysis, produce clear documentation, and integrate with BIM platforms like Autodesk Revit. 

Orion is a structural analysis, design and drafting program developed for the design of building systems. The program consists of several modules for performing the following tasks:

• 3-D Analysis of the structural model of the building
• Column, Wall and Beam Reinforcement Design
• Column, Wall and Beam Detailing
• Foundation Design
• Analysis and Design of Stairs
• Concrete and Steel Quantity Extractions

The analysis module has been specifically developed to model building type structures. The integrated Graphic Editor accelerates the model creation process, minimising possible user errors and thus yields a more reliable design.

General characteristics of a building system can be summarised as follows:

•  Building geometry generally consists of horizontal (or inclined) beams and vertical (or battered) columns.
• Most of the beams and columns in the model have similar section properties. Therefore, they can be grouped into different types and size of the data input files can be shrunk recognizably. However, it must be possible to model all type of column sections. (with or without holes)
• Slabs with relatively higher in-plane stiffnesses, are utilised to form separate or complete rigid diaphragms at the same floor level.
• Vertical loads (dead and imposed loadings) and floor level horizontal loads (wind and earthquake or notional horizontal loads) act to the model. For special cases, individual columns or walls may be exposed to nodal loading (force and moment) in all directions. Besides these, direction dependent dead and live loads must be acquainted for in the usual building systems.
• Member sizes must be considered during analysis phase and all effects must be calculated at member faces.
• Rigid zones at column-beam connections must be modelled in detail together with possible symmetric or asymmetric hinges.
• Wall members have a significant effect on building behaviour. Therefore, modelling of these members must be as close to the real as possible. Alternative options must be supplied for cross-checking.

Users spend most of their time checking the output reports and trying to find the member results in the analysis outputs. Analysis results generated by Orion’s Analysis Module are summarised and transferred automatically to design modules after the analysis stage.

Orion includes the code of practice requirements for each supported region. In all stages, necessary checks are carried out automatically by the program.

Orion should only be used by Structural Engineers who have considerable knowledge of:

• Codes of practice and regulations used in their region
• Analysis and design of building type structures

Orion has been tested on numerous structural models before being released. However, in all cases, the user is the sole person responsible for the results generated by the program. The user must therefore check the program output before using it in a design.
