In structural engineering, a modal analysis uses the overall mass and stiffness of a structure to find the various periods at which the structure will naturally resonate, along with the frequencies of vibration of the structure. In RISA-3D, the modal analysis is a prerequisite to the response...
The latest release of ADAPT-Builder 2019 includes improvements that include new tools for meshing, tendon force input and releasing the edges of shells.
Reinforced and post-tensioned concrete structures in today's construction environment demand more efficient and reliable analysis, design, and BIM workflows. ADAPT-Builder offers a seamless and fully-integrated approach for modeling, analysis and design for single and multi-level post-tension...
Color contours and gradients can be very helpful to visualize the forces/stresses of plates and wall panels. But did you know there are other design tools that can be helpful in analyzing and understanding these contours? The family of Internal Force Summation Tools (IFST, IFST Wall and IFST Slab)...
We are excited to announce that one of our own, Dr. Cheng Song PH.D, PE, was recently named the 2020 Young Engineer of the Year by the SEA of Southern California for his work as co-chair of the Younger Member committee.
One of the questions our support team receives often is the difference between Basic Load Cases (BLC), Load Categories and Load Combinations (LC). Understanding how these containers are used and how they work together when loading a structure is an essential part of creating an accurate model in...

RISAConnection Version 12 now supports skewed shear tab connections. With this enhancement, engineers have the option to skew a wide flange, a tapered wide flange or a channel beam with the following supporting members:
RISA-3D can be used to model the effects of rotating machinery on their support structures. In the model below, we have a structure which is to support a piece of rotating machinery.
