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.
The ASCE/SEI 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures introduces significant updates from ASCE 7-16. The most notable changes impact wind and seismic provisions, along with new load combination rules that directly affect structural analysis and design. With the release of RISA-3D v23, engineers can now take advantage of these updates directly within their workflows. Why This Matters for Engineers? The most impactful provisions of ASCE 7-22 — wind, seismic, and load combinations — are now supported in RISA-3D v23, ensuring your projects remain compliant with the latest building codes and IBC 2024 adoption. Download the latest versions of RISA that supports ASCE 7-22 below. 1. Wind Provisions Key changes in ASCE 7-22 affect wind speed maps, velocity pressure equations, and roof zone definitions. Topic ASCE 7-16 ASCE 7-22 Design in RISA Wind Speed Maps Based on 2016 hurricane data Updated hurricane & transition zone maps RISA-3D generates wind loads per ASCE 7-22, reflecting updated maps Velocity Pressure (Kd) Included directionality factor Kd removed Automatically handled in RISA-3D wind load generation Roof Zones Based on h/B ratio for hip roofs h/B removed; new GCp values and roof zoning RISA-3D applies updated coefficients for accurate roof…

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...
Wide Flange Beam to HSS Tube Column Moment Connections can now be designed in RISAConnection version 9. HSS tubes may be selected as the supporting column member on either of the two moment connections:
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...
