How Do I Consider Welded Aluminum Connections in RISA-3D?

In Aluminum design, the welded areas have a decreased material strength and RISA-3D can assign any material strength to the members based on the Material spreadsheet. The default materials provide one welded material: 6061-T6 W, but you can enter your own welded materials by pressing ENTER at the bottom of the spreadsheet. To use these reduced strength welded properties, you need to break up the member into smaller segments that are influenced by the weld. A good tool to create the segments is the "Split Members" option listed in the Modify tab of the ribbon toolbar. Below is an example of a truss, where the welded joints are shown using a different section set and material in green. You can use the graphical display options to understand your model’s code check, forces and much more…

Canadian Wood Design now Available

Timber design per the Canadian CSA 086-2009 design code is now available. Canadian wood member design is very similar to the US NDS member design. There are slightly different load factors, material properties, shape tables, and capacity equations, but the overall modeling procedure in RISA is the same. Selecting the Canadian Design Code Start by selecting the “CSA 086-09: Ultimate” code from the Codes tab of Global Parameters: Setting up Canadian Wood Materials The next step is to set up your materials. As long as you have selected the Canadian wood design code (as shown above), the program will know to use the material properties per the CSA 086-09 Tables 5.3.1A-D. These properties depend on the material selection and the shape selection. Setting up Metric Shape Members Wood shape selection depends on your selected units. If you are using metric units then you will be able to select your shape from the list of standard metric shapes, or manually enter a full sawn size using mm: If you are using imperial units then you will be able to select your shape from the list of standard imperial shapes, or manually enter a full sawn size using in: Design Results After…

Methods to Integrate with RISAConnection

There are several ways to take your RISA-3D or RISAFloor model to RISAConnection. The RISA-3D and RISAFloor end reactions can be sent directly to RISAConnection or RISAConnection can be operated from within RISAFloor and RISA-3D. Below are the two methods to send the information from RISA-3D and RISAFloor to RISAConnection. 1. With a Single or Batch solution present, take the RISA-3D or RISAFloor model to RISAConnection using the Director button in the upper right corner of the screen. 2. In RISAFloor, click the RISAConnection icon to take all of the member end reactions to RISAConnection, analyze the connections, and return connection results to RISAFloor. This all happens without opening RISAConnection. In RISA-3D, with a solution present, you can choose to Design Connections from the Solve dialogue. The member end reactions will be sent directly to RISAConnection and the connection results will be sent back to RISA-3D without opening RISAConnection. Once the connections are designed in RISAConnection, take the information back to RISA-3D and RISAFloor by pressing the Export to RISA-3D/FL button within RISAConnection. The Connections Results will be present on the Results toolbar and this spreadsheet will summarize the connections and controlling limit states for code check. With the Connection…
