How to Add a New Pattern to the Moving Load Database
RISA-3D and RISA-2D come with a default list of existing moving load patterns. These are listed in the Moving Loads Library which can be viewed by clicking on the Moving Load Patterns button in the Advanced tab.

How to model a Geodesic Dome in RISA-3D?
In modeling what would be a rather difficult geometric structure, by using the Templates database in RISA-3D, a geodesic dome can be constructed rather quickly and easily.

Designing Built-Up Sections using RISA-3D
Use RISASection to find the properties of built-up steel sections, then model beams using the same section properties in RISA-3D and get full code-checks using AISC 360. This webinar will teach you how to use RISASection quickly and easily to determine complex section properties.

How Do I Model a Tapered Pipe?
Tapered members are common for metal buildings and pole-type structures. For tapered wide flange members RISA provides a quick way to generate a tapered section that can then be checked per the provisions of AISC Design Guide 25 on tapered wide flanges.

What are Web Doubler plates used for in RISAConnection?
For moment connections in RISAConnection there is an option to place web doubler plates on the column web. These plates act as a reinforcement for the column web to prevent panel zone shear failure. As shown below, when the flanges of a beam in a moment connection connect to a column they form a...

Why Is My Beam Failing in Shear?
When solving a RISA-3D model you may find you have a Shear UC (unity check) much higher than expected from bending shear alone. If you open the detail report and compare the shear demand to the shear capacity you may see that the demand/capacity is less than the Max Shear Check reported.

What is the Tau b Factor and how does it affect my analysis?
When solving a RISA-3D model with hot rolled steel members under the AISC 360-05 (13th Edition) or AISC 360-10 (14th Edition) codes you may find references to a factor called Tau_b. To understand what this factor is you should first be familiar with the Stiffness Adjustment in RISA-3D, then see the...
