Plate Contours Compared to Spreadsheet Values
After solution in RISA-3D, you can use Results View Settings to view the Plate Contours graphically on your model.
The 4th of July is a time for celebration, fireworks, and, of course, a bit of fun. For those with a knack for engineering or simply looking to engage in some creative activities, why not take on some patriotic engineering challenges? These activities are perfect for kids and adults alike, providing an entertaining way to celebrate Independence Day while sharpening your problem-solving skills. Here are three exciting challenges to get you started: 1. Popsicle Stick Bridge Materials Needed: Popsicle sticks Glue (wood glue or a hot glue gun) Small weights (coins, toy cars, etc.) Challenge: Design and build a small bridge using only popsicle sticks and glue. The goal is to create a bridge that can support as much weight as possible. This activity not only tests your creativity but also your understanding of structural integrity and load distribution. Instructions: Plan Your Design: Before you start gluing, sketch out a design for your bridge. Consider different types of bridges, such as beam, truss, or arch bridges. Build the Foundation: Begin by constructing the main supports for your bridge. Glue several popsicle sticks together side by side for a strong base. Assemble the Bridge: Connect the supports with horizontal and diagonal…

The applied loads in a response spectrum analysis (RSA) are the applied masses times the accelerations in the response spectra. Each mode of vibration produces its own set of joint reactions. The reactions for each mode obey statics as shown in the portal frame example shown below: Response...
In order to get code calculations, RISA-3D and RISA-2D need to know what type of shape would be most similar to yours. This is because the program needs to use the correct code equations for your shape type.
Investigating P-Delta instabilities in RISA-3D (or RISA-2D) can be difficult. The first step is usually to solve the model without the P-Delta effect included to see if there are any obvious deflection problems that could cause issues with a P-Delta analysis. But, what can be done when this doesn’t...
Students and Professors can utilize a special version of RISA-2D which is aimed at teaching and understanding the basics of structural analysis. While this version has a limited number of features, it will prove to be a useful tool in expanding the students structural engineering knowledge.
RISA-3D, RISA-2D and RISAFloor have the capability to project distributed and area loads onto members. Consider the case of snow load on two buildings: one with a flat roof and one with a sloped roof. Ignoring the concept of shedding, if both buildings have the same footprint then they should both...
While RISA-3D (or RISA-2D) does not have an explicit tool to punch a hole in a plate, you can use the following steps to manually model them:
The bending and axial code checks for single angles differ somewhat from other shape types, because single angles behave quite differently in bending and compression depending on how they are braced along their length.
When your RISA-3D model is not behaving as you anticipated, one of the best tools you have is viewing the deflected shape. Displaying the deflection graphically will help you visualize how the model is behaving and will often times bring to light modeling errors.
