How to Create and Apply A Custom Rebar Layout
Applying a Custom Rebar Layout in RISA-3D: To begin creating a custom rebar layout, simply click the Custom Rebar Layout button located in the Advanced tab of the ribbon toolbar.
RISACalc in the Field: A Case Study in Confidence and Convenience It was a typical Thursday morning for Emma Ruiz, PE, a structural engineer at a small consulting firm in Colorado. Her day started with a site visit to a rural school renovation—a project where her team was assessing whether a portion of the existing structure could support new rooftop HVAC units. The original framing plans were incomplete, and as Emma inspected the roof framing, it became clear that the contractor’s proposed unit placement didn’t line up with the assumed beam layout. A decision had to be made, and quickly—the rooftop unit was scheduled for delivery the following day. The Problem: Time-Sensitive Field Check Emma didn’t have time to return to the office to rebuild a full model or dig through spreadsheets for older framing checks. She needed to verify—on the spot—whether the existing W10x22 steel beam could support the new loads at the proposed spacing. The contractor waited, the facilities director asked for reassurance, and Emma pulled out her tablet. The Solution: RISACalc in Action Emma opened RISACalc, selected the beam design template, and input the beam size, span length, and newly calculated roof loads, including snow and equipment…

Modeling tapered gusset plates in RISAConnection is now easier than ever. With the recent addition of the Custom Angle input, you may now enter an angle to quickly cut back a gusset edge.
The base material at the location of a weld may have less strength than the weld itself. In this case it will control the overall strength of the welded connection. In order to account for this, RISAConnection uses a weld strength reduction factor (α) which we call the Base Material Proration...
Wide Flange beam to HSS Tube column moment connections can now be designed in RISAConnection version 9 with both the US and Canadian design standards. HSS tubes may be selected as the supporting column member on either of the two moment connections:
RISAConnection assumes by default that your vertical brace connection is a one-sided connection without any outside influence or load transfer from other connected elements. Using this assumption, the design shear and axial force at the beam to column sub-connection is determined using simple...

RISAFoundation v11.0 includes two new tabs in the Safety Factors results spreadsheet that breakdown the slab’s stabilizing and destabilizing forces for each category. The new Overturn/Resist by Category and Sliding/Resist by Category tabs make it easy to understand how the program calculates the...
In RISA-3D, the current method of design for masonry lintels is Simply Supported where the masonry lintels are idealized into a simply supported pin-pin beam configuration. Now, masonry lintels can instead be analyzed using finite element analysis. With this method, the lintel will be fully...
RISAFoundation can apply soil overburden to a mat slab to account for the weight of the soil above the foundation. Simply enter a Soil Overburden pressure value for your foundation design in the Slabs spreadsheet. The soil overburden load is utilized to help the mat slab resist overturning during...
