ORION 18: HOW TO ADD LOAD TO A SINGLE SLAB

For this tutorial, we will learn to impose a line and Area Load for a slab.

Step 1

Click in the members toolbar at the top of the screen.

Step 2

 Click . Click the upward arrow next to "Load Case 1: Dead Load" box to display and select "Load Case 2: Live Load". To ensure a UDL line load, we will make w1 and w2 to be the same in the 'Slab Load Properties' dialog box. If we make w2 bigger, the loading will be trapezoidal, increasing from point 'w1', the first point selected, up to the other end of the loading. We insert UDL length of 5000mm (length of beam.) Insert w1 as 3KN/M (w2 automatically takes the same value, though this can be changed for varying distributed load, VDL.) Click the centerline of the adjacent beam to create the line load (location of w1) to create the load.

Step 3

 To insert an area load into 'Slab: 1S4', Click in the "Load Slab Properties" dialog box that appears after step 1. Enter 'b1' and 'b2' as 5,000mm and 14,000mm, the horizontal and vertical sides of the slab. Click the intersection of the beam centerlines at the bottom left side of the slab to insert the area load. Click 'OK' in the 'Slab Load Properties' dialog box.
