RISA recently completed renovations to their Foothill Ranch, CA office. The renovations include a new kitchen and coffee bar, new conference rooms and updated open office concept that allows various departments to easily work collaboratively together.
RISAFloor v13 includes a variety of modeling features which allows users to quickly create and manipulate geometry. These features include construction lines, saved selections and copy elements from floor to floor. Overall, these features can be used to help engineers streamline their modeling...
RISA-3D v17.0 now has the ability to model partial fixity member end releases. Partial fixity end releases can be utilized in RISA to model the behavior of a partially restrained or semi-rigid connection that cannot be idealized as fully fixed or pinned. Partially restrained connections are common...
The new AWC NDS 2018 code has been implemented into RISA-3D v17.0 and RISAFloor v13.0. To select this code for your design, simply choose this code from the Codes tab within Model Settings.
RISA-3D v15 includes "analysis offsets" which moves the centroid of the member for analysis allowing for flexibility in how members are designed. Let's use a WT brace to demonstrate how this feature can be utilized. When you model a WT brace it exists at the member centroid, which means that no...
In a previous article we discussed how the Analysis Offsets feature in RISA-3D works and how it can be used to model members at top of steel. In this article, we will discuss some specific situations and how the results change with the analysis offset set as top of member (local -y axis).
Have you ever wondered what the Analysis Offset feature does? Let’s take a look at how this feature can be used to model members at top of steel.
RISAFoundation includes the added ability to enter a passive pressure for slabs. The passive pressure represents soil pressure along the perimeter of the slab and will contribute to the sliding resistance of the slab.
The new AISC 360-16 15th Edition changes have been implemented into RISA-3D v17.0 and RISAFloor v13.0.
