Battered Retaining Wall Design
The batter dimensions can be set from Wall Footing Definitions:
If you've ever wondered what it’s like to be an industrial structural engineer, let me paint you a picture: Imagine juggling a dozen problems at once—steel frames, conveyor supports, pipe racks, tank foundations—all while trying to decipher a set of drawings that look like they were faxed from 1997. And, of course, every single solution is needed yesterday. But don’t worry! With the right tools (cough RISA and ADAPT cough), navigating this daily chaos becomes a lot more manageable. So, grab your coffee (black, obviously), and let’s walk through a typical day. 6:30 AM: Morning Coffee & Evaluating Additional Loads The first email of the day: “Can we add another 10,000 lbs of equipment to the mezzanine? What about seismic drift and vibration?” Instead of a lengthy hand calculation, you fire up RISAFloor and check gravity load distribution. Exporting to RISA-3D, you analyze modal frequencies and check if the additional weight will push the structure into an uncomfortable range for human occupancy. Seismic drift is next. A quick response spectrum analysis in RISA-3D confirms that the drift is still within acceptable limits. You send your report with confidence—no major framing changes required. 9:00 AM: Field Issue - Pipe Rack Base…

RISAFloor is a design program in which it takes basic shape criteria about your beam or column members and then selects an optimal size to meet strength and serviceability criteria. However, the program can just as easily perform a design check for an as-built condition by defining specific member...
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.
Have you been in RISAFloor performing a steel product design and noticed an (SP) extension to a joist designation? The following will discuss when the program designs for these special loading conditions.
You may notice discrepancies in the wood design values when comparing RISA with the NDS 2012 and older versions of the code. The American Wood Council updated the wood design values in the Addendum, which supersede the values used in the NDS 2012 and previous versions of the Design Values for Wood...
After solving a model, you will see in the Member Deflections spreadsheet the following deflection ratios:
The beams in a lateral force resisting system, such as a braced frame or moment frame, typically carry a significant axial force. In the example below (with no diaphragms) the beam (M4) carries a significant axial tension.
Revit offers two options for setting the elevation of beams. The way these are used has a significant impact on how those members are round tripped to RISAFloor, so it is important for you to use them correctly. The Level Offsets are available at each end of the beam. They can be modified through...
In the Seismic Loads dialog there is a checkbox for “Include structure weight in base shear”.
