ASCE 7-16 Is Now Available!
The 2016 edition of ASCE Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE 7-16) is now available in RISA-3D v17.0, RISAFloor v13.0, and RISAFoundation v11.0!
With the adoption of ASCE 7-22, the concept of a multi-period response spectrum has been added to seismic design requirements. While this provides more accurate hazard representation, it also means engineers need to generate and input additional site-specific data. This quick workflow shows how to gather that data from the ASCE Hazard Tool and use it in RISA’s site parameters table for seismic load generation. Why This Matters for Engineers? Multi-period response spectra reflect more realistic ground motion characteristics and will increasingly be required as jurisdictions adopt ASCE 7-22. By pulling site-specific values directly from the ASCE Hazard Tool, engineers can ensure compliance and avoid unnecessary assumptions. The multi-period approach can result in higher or lower design forces depending on the building’s period and site class, but it always provides more accurate seismic representation than the traditional two-point method. Download the latest versions of RISA that supports ASCE 7-22 below. Step 1: Generate Multi-Period Spectrum Data Go to the ASCE Hazard Tool. Enter your project location (address, coordinates, or site description). Select ASCE 7-22 as the building code. Navigate to the seismic hazard results and download/export the Multi-Period Response Spectrum data. Step 2: Copy Data Points into RISA Open RISA…

The 2016 edition of ASCE Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE 7-16) is now available in RISA-3D v17.0, RISAFloor v13.0, and RISAFoundation v11.0!
RISAFoundation includes the added ability to enter a passive pressure for slabs. The passive pressure represents soil pressure along the perimeter of the slab and will contribute to the sliding resistance of the slab.
For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design.
Concrete pile design is now incorporated in the pile cap results in RISAFoundation. With the addition of axial pile design in RISAFoundation v10.0, the program can model concrete pile shapes and design the reinforcement, or the user can also apply their own custom rebar layout. Now you can get a...
RISAFoundation has the capability to consider seismic loading for retaining walls.
We are proud to introduce drastically improved solution times in RISAFoundation version 10.0. This version was updated to include multi-threading/parallel processing capability which will allow it to take advantage of multiple core processors which are becoming extremely common on the market today.
The new TMS 402-16 Masonry Code (formerly designated as ACI 530 and ASCE 5) have been added to RISA-3D v16.0, RISAFloor v12.0 and RISAFoundation v10.0.
Hot rolled steel, wood, and concrete piles are now available in RISAFoundation v10.0. The Pile Definition Editor lets the user input the pile’s properties including the pile’s shape, material, and length. For concrete piles the user has the ability to apply a custom shear and flexural rebar layout...
With Pile Design in RISAFoundation, you have the ability to define the default soil properties for the entire model. But also the Soil Definitions spreadsheet gives you control over all the soil property layers in one location.
