Custom Column Strip Widths
RISAFloor v11 now includes the ability to create custom column strip widths in order to optimize the design of slab reinforcement.
The winter months bring a unique set of challenges to structural engineering: projects slow down, site conditions become less predictable, and downtime can be harder to avoid. However, this season also brings opportunities to work smarter, streamline workflows, and plan ahead for a productive year. Here’s how you can help keep projects on track even in the frostiest months. 1. Winter Prep: Tackle Delayed Analysis Cold weather is often the perfect time to tackle those time-intensive analyses that may have been put on the back burner. With RISA-3D’s robust modeling environment, winter downtime becomes the ideal chance to dive into in-depth analysis and design. RISA-3D lets you quickly model complex geometries and visualize load paths in ways that manual calculations simply can’t replicate. And for foundation design, RISAFoundation can handle everything from frost heave assessments to wind uplift forces, enabling you to get the clearest picture of how your structures will withstand winter’s impact. Take advantage of the winter slowdown to refine and validate your foundation designs, ensuring every project element is prepared to endure the season. 2.

RISAFloor v11 now includes the ability to create custom column strip widths in order to optimize the design of slab reinforcement.
RISAFloor ES allows you to model concrete slabs of any thickness. However, there might be sections of the building that require a thicker slab. The icon is shown below and it will allow you to draw a Polygon or Rectangular shape.
In RISAFloor ES, you can quickly thicken the slab in the column strip area with the Drop Panel tool. The column strip is typically the area of highest demand so increasing the thickness may help optimize the concrete usage.
The new ACI 318-14 code has been implemented into RISA-3D v14, RISAFloor v10, and RISAFoundation v8.
The batter dimensions can be set from Wall Footing Definitions:
In RISAFoundation, Design Strips are used to create regions in a slab for reinforcement design. Design strip size and shape is determined by the user, see the Help- Slab- Design Strip Width topic.
Per the ACI, you can add a Shear Cap to your column to increase the shear strength of the slab. In RISAFloor ES two-way slabs, adding a shear cap will thicken the plates around the column automatically. The Shear Cap will affect the Punching Shear and the One-Way shear calculations. As you draw the...
RISAFloor Concrete Floor Slabs can design be transferred into RISA-3D for lateral design using either a Rigid Diaphragm or Semi-Rigid diaphragm. In RISA-3D, the wind and seismic loads are calculated and then applied into the diaphragm level to distribute the forces to the Lateral Resisting System.
Concrete buildings often have large cantilevers. In RISAFloor ES, the Support lines can be drawn to support points but also they can be drawn as cantilevers (shown below).
