AISC 341-16 & AISC 358-16 now included in RISA-3D
The AISC 341-16 and AISC 358-16 Edition changes have been implemented into RISA-3D v19.
While members (beams and columns) follow conventions tied to their local axes, interpreting results for wall panels, plate elements, and design strips requires a slightly different perspective. These elements deal with both in-plane and out-of-plane behavior, and the sign conventions can change depending on the program and axis orientation. Overview Table of Sign Conventions Element Type Positive Moment (M) Shear (V) Axial (P) Notes Wall Panels – In-Plane Compression in positive local-y face Downward on right face Tension = Positive Applies to in-plane forces only Wall Panels – Out-of-Plane Compression on positive local-y face N/A N/A Defines “positive bending” convention Plates (RISA-3D) Positive Mz = Top surface in compression Shear follows right-hand rule Tension = Positive Local Z-axis defaults upward Plates (RISAFoundation) Positive Mz = Top surface in compression Shear follows right-hand rule Tension = Positive Local Z-axis defaults downward Design Strips / Support Lines Sagging = Positive (bottom fiber in tension) Downward on right face Tension = Positive Matches slab design workflows Wall Panels Wall panels report forces in both in-plane and out-of-plane directions. In-plane: Axial = Positive tension Shear = Positive when downward on the right face Out-of-plane: Positive bending = compression on the positive local-y face of…

The AISC 341-16 and AISC 358-16 Edition changes have been implemented into RISA-3D v19.
The new ACI 318-19 code has been implemented into RISA-3D v19, RISAFloor v15, and RISAFoundation v13. One of the biggest changes between the ACI 318-14 code and the ACI 318-19 code is the shear contribution provided by the concrete, Vc.
Recent tests and analytical results for concrete columns have indicated that considering shear along each centroidal axis independently can be unconservative. Therefore current versions of RISA-3D, RISAFloor and RISAFoundation have included the consideration for the interaction of shear forces...
The Quick Start Course is a 4-hour introduction to the basic features and functionality of RISA-3D that utilizes expert instruction and example models to familiarize users with the user interface as well as the main workflow of modeling, loading, analyzing, designing and documenting a model in...
Watch the recording of our webinar to learn how new versions of RISA-3D, RISAFloor, RISAFoundation and RISAConnection provide users with expanded design capabilities, improved product integration and new features including:
Overview FRP or Fiber Reinforced Polymer (thermoset) composite materials are becoming more and more popular in the construction world of today. There are many reasons for using composite materials, which go beyond the scope of this article but suffice to say that composite/FRP materials are now...
If you have utilized Hold-Down's in RISA-3D, you have mostly likely noticed that a value of CD is reported for each selection in the database. However, it may not be clear how it is being used?
In the Node Reaction spreadsheet, all reactions from node-based boundary conditions are reported. If you look closely at some models, there may be wall panel labels in the Node Reactions spreadsheet as well. This may cause users to ask the question:”what are these reaction values for a...
Learn how to build custom steel and concrete shapes using RISASection and then import them into RISA-3D to incorporate them in analysis and design.
