Tutorial 3 – Loading
In this tutorial we will load the model we defined in the last tutorial. Make sure
you start off correctly by opening the file mentioned next.
After starting RISA-3D click the Open File button. In the File Open dialog
select the file named “RISA-3D Tutorial 3 Starter” and click Open. Close the
Global Parameters window by clicking OK and we will begin working in the
model view. Click to close the Data Entry Toolbar if it is open. Your
screen should look like this:
Load Cases, Categories and Combinations
Before we load the model it is important to understand just how RISA-3D lets you
manage loads. When loads are defined in RISA-3D they must be assigned to a
“Basic Load Case” which are simply sets of loads. You can have up to 1000
separate Basic Load Cases (BLC's). You also have the option to assign the BLC’s
to categories, which help you easily combine them later in the model solutions.
When you are ready to solve the model, the BLC's and categories are combined
(with multipliers) into one or more load combinations.
Open the Basic Load Cases spreadsheet by selecting it on the Spreadsheet
menu.
Let's enter a description for each of the BLC's we'll be using. The active cell
should be in the first row and first column, which is the BLC Description field
for BLC 1.
