HSS Tube Moment Connections per AISC 360 now Available

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:

Column/Beam Direct Weld Moment Connection
Column/Beam Flange Plates Moment Connection

You may select rectangular or square tubes and all design codes are supported (AISC 13th, 14th, CSA S16-09, and CSA S16-14) for the design of these connections.

Design for these connections is presented in detailed limit state checks just like all other RISAConnection results. Each limit state can be expanded to see the details of the check.

Vertical Slab and Beam Offsets

In RISAFoundation, you can add a vertical offset for slabs or beams. Traditionally, RISA uses centerline analysis which aligns all elements at their centerline. This is a common structural analysis assumption as the loads will get transferred to the centerline even if there is difference in the sizes. In certain circumstances, it becomes necessary to model the offset because the elements are very different sizes and you need to address the eccentricity. You can modify the slabs or beams using the Analysis Offset either graphically or in the spreadsheets. The slab or beams can be offset in the downward direction…

HSS Tube Moment Connections per CSA S16 now Available

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: Column/Beam Direct Weld Moment Connection Column/Beam Flange Plates Moment Connection When either of the above connections are designed per the Canadian design codes (CSA S16-09 or CSA S16-14), the HSS limit state checks are done per the appropriate equation in the CIDECT Design Guide 3, Table 7.1. These limit states are all applicable only within a certain range, so RISAConnection checks the applicable ratios in the HSS Limitations check. If this fails, then the connection geometry is outside the “Range of Applicability” from the CIDECT Design Guide 3 Table 71…

Connection Design per Canadian Steel Code (S16-14) now Available

RISAConnection now offers connection design per the Canadian CSA S16-2014 design code. Selecting the Canadian Design Code Select the Canadian S16-14 design code from the list of available Design Codes on the Solution tab of (Global) Project Settings: Design Results Once selected, the results report will automatically update your results per the CSA S16-2014 design provisions:…
