Rebar Design using the Internal Force Summation Tool in RISA-3D

When you have a plate model for a slab or wall in RISA-3D, the Internal Force Summation Tool (IFST) is a very useful analysis tool to get exactly the forces that you want to design for. To use the tool, you must: Be looking at the model in a plan or elevation view (i.e. 2D View only). Have selected ONLY the portion of the model that you want to sum the forces for (all other elements are Un-selected). Let’s look at a slab example. Here we have an elevated slab that is supported on all edges, with a column that lands in the center of the slab. The slab is modeled with plate elements. After we solve the model for that load, we can view our plate contours and use the selection tools to select a representative strip. The representative strip would be a strip through our slab/wall that we want to get the forces for so we can then design reinforcement for this strip. To use the IFST, select the button on the left side of the screen. Clicking twice on our strip will create a plane that the program cuts through the model and will then display the…
