MODELLING ON CSC ORION

MODELLING ON CSC ORION Orion is a structural analysis, design, and drafting program developed for the design of concrete building systems (CSC Orion Reference Manual). The program consists of several modules for performing the following tasks; [1] 3-D Analysis of the structural model of the building [2] Column, Shear wall, Slab, and Beam reinforcement design [3] Column, Shear wall, and Beam detailing [4] Foundation design and detailing [5] Analysis and Design of Stairs [6] Concrete and Steel Quantity extractions Unlike general purpose structural analysis program, Orion is concentrated on accurate analysis, fast data preparation, automated reinforced concrete design, and automated preparation of engineering drawings and details. In summary, Orion model allows you to; [1] Create GA drawing [2] Design the floor slabs, and decompose floor loads onto the beams [3] Analyse the building frame [4] Design continuous beams, columns, walls, and foundation [5] Automatically generate RC detail drawings Having completed your general arrangement, you have to go into modelling of the structure. GA is the first step, irrespective of whether you are undertaking manual or computer-aided analysis. It is assumed that you have already purchased and installed Orion software package on your computer. There are many approaches of modelling in Orion like importing from other software etc. But in this text, I am concentrating on modelling from scratch. The structure below is our end target.

Final Target Model on CSC Orion [1] GETTING STARTED Launch the Orion Software. On launching, this dialogue box below comes up;

Click on New Project. Enter the Project Code of your choice. In this case, note that no spacing is allowed on the project code. You can use underscore to separate words. Hit the ENTER button On hitting the ENTER button, the Settings Centre Dialog box comes up as shown below. Select UK(Eurocode), and ensure that that all the parameters on ‘Current Project Settings’ are checked. Then click on IMPORT.

Select your ‘sheet data as you desire, and click OK. Note that various sheet sizes like A2, A3, A4, A5 etc are available from the drawdown menu. Specify as desired and click ok.

At this point, the graphical user interface (GUI) comes up, shown in the diagram below. The green rectangle on the screen represents the sheet size you have selected in the previous dialogue box. Now, we wish to create the GA of the building. By this time, you should have manually prepared your GA (could be a rough sketch), and have accurately placed your beams and column where you desire them to be. In this case, note that the GA we want to prepare has been shown above, you must have carefully specified the preliminary structural dimensions of your elements, and the concrete cover viz; Dimensions of columns (In this case 230 x 230 mm) Dimensions of all floor beams (In this case 450 x 230 mm) Dimensions of roof beams (In this case 250 x 230 mm) Thickness of slab (h) = 150mm
