Section Sets Spreadsheet
On the Data Entry Toolbar click on and this window will open:
Repetitive members are inherent in structural design and Section Sets provide an
easy way to handle them. This will become even more apparent when we have
RISA-3D pick new / optimized member sizes. Our truss has only nine web
members but what if we had three trusses and we had to change the section, which
we will do in part two of this tutorial. Changing 27 member properties could take
some time if you had to do one at a time. The ability to define section sets means
you will only need to change one section on this spreadsheet to globally change
the truss web member properties.
Hot Rolled Sections and Database
We already have one section set for each material type. Lets add some section
sets and change the labels so that they are more meaningful. The active cell
should already be the cell that contains the text “HR1”. We haven’t yet defined
any members with this section, but will be using it for the beams that span in the
Z direction.
Give the section a more descriptive label by typing the following:
Beam-Z, [ENTER]
The spreadsheet should now look like this:
Note that pressing ENTER has also created a new line, which we do not need for
our model. This will allow us to demonstrate how to delete a line.
Remember that the Window Toolbar will change as you move from window to
window so that the buttons are relevant to what you are currently doing. It now
looks like this:
Click the second button
, which deletes the current line.
