RISA-3D Version 19 now includes the ability to define the plate methodology of a material as orthotropic. In structural analysis and design, it may be useful to define plates or slabs that have different characteristics (stiffness) in the longitudinal and transverse directions. Doing so will result...
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)...
With many of us working from home, our support team wanted to be able to connect with our customers where they are: in front of their computers. With that in mind, we are excited to introduce RISA Live. These live sessions, will take place every Thursday at 2pm EST (11am PST) and will focus on...
RISA-3D now includes improved behavior of the automesh feature as well as the newly added global model setting for Plate Local Axis. The new plate local axis options include both Nodal and Global. These options allow for more control over plates which can lead to clearer results in plate contour...
It is important to submesh plate elements in your model in order to obtain the most accurate results. However, many users wonder what the approximate guidelines for plate dimensions are acceptable.
Transitioning plates from a circular (or elliptical) to a square (or rectangular) shape can be done easily using some of RISA-3D’s automated generation tools. Below is the procedure for transitioning a circle into a square, but it should be clear how this could be accomplished for other similar...
Below is a model of a flat concrete slab made of plates. In order to ensure adequate serviceability of the slab, you may need to check the deflection of the slab between columns. However, RISA-3D only reports Member and Joint Deflections. There is no such thing as a “Plate Deflection”.
After solution in RISA-3D, you can use Results View Settings to view the Plate Contours graphically on your model.
