In this tutorial, we will learn how to design slabs in Orion 18.
By the end of this tutorial, you will be able to easily carry out code based design of slabs and to print out the results.
Step 1
Before we start the structural design of the slab, let us establish the settings to be used. Click ‘Settings’, then select ‘Slab Design Settings’ from among the options. Click the ‘Steel Bars’ tab and change ‘Bar spacing’ (under ‘Min’ to 75) and (under ‘Max’ to 300).
Step 2
Step 3
In the ‘Slab strip Properties’ dialog box, set the ‘Type’ to ‘Analytical’ and select ‘Bob’ and for ‘At Start’ and ‘At End’ respectively. This option ensures that both the top and bottom steel as well as the support steel is designed for the slab. It also ensures that the support steel at the edge is bent into the beam/wall.
Hold ‘ctrl’ on the keyboard, then beginning from outside the first slab on the left (3/A, 3/B, 1/A, 1/B), click and drag horizontally across the slab. The ‘ctrl’ button is to ensure that the slab strip is completely vertical or horizontal. The bar detailing for the main bars (including the support) appears, as well as the length of each bar type.
To design for the secondary bars, begin from outside the same slab, Click and drag vertically across the slab from top to bottom. The bar detailing for the distribution bars appear as was done for the main bars.
Repeat this procedure for all the slabs.
ALTERNATIVELY,
Draw a horizontal slab strip starting from left of the first slab to the right of the last slab to automatically carry out the main bar detailing of all the slabs, Distribution detailing will still need to be carried out individually though.
Step 4
A preview of the report is shown which can then be printed out in different formats.
To produce a PDF or Excel format of the result, click ‘PDF’ or ‘TDF’ at the top of the screen.
