If you are already familiar with structural modeling in general you can skip the supporting text and read only the underlined action items to move through the tutorials very quickly. To do this read the rest of this Before You Begin section and then skip to page 6 and look for the underlined action items. If you want more thorough explanations of the modeling process you may read all or some of the supporting text as you see fit. The tutorials are intended for the first time user of RISA-3D or those who need a refresher on how the program works. To complete this guide in its entirety will take less than an hour if you perform only the underlined action items mentioned above or 3 to 4 hours if you read all of the supporting text. We’ve broken the tutorials up so you don’t have to do it all at once. The tutorial is intended to teach you the basics of defining and solving models in RISA-3D, and also how to review the results. We won’t go into a lot of depth regarding the analytical aspects of RISA-3D here; that’s what the RISA-3D General Reference manual and on-line help file are for. What we will cover is how and when to apply RISA-3D features to help you be most productive. For example, we’ll perform steel, concrete and wood code checks in this tutorial, but we won’t discuss the specifics of how those code checks are calculated; that is covered in excruciating detail in the General Reference sections Steel Code Checking and Design, Concrete Code Checking and Design, and Wood Code Checking and Design and also in the help file. After you have gone through the User Guide, use the General Reference and On- line Help for detailed information on any topic. The topics are summarized in the table of contents and are thoroughly indexed.
