The American Iron and Steel Institute (AISI) has published two new cold-formed steel research reports: 1) “RP18-2: Design Example for Analytical Modeling of a Curtainwall and Considering the Effects of Bridging (All-Steel Design Approach)” and 2) “RP18-3: Determination of Effective Standoff in Standing Seam Roof Systems.” Both of the research reports are available for free download here.
“RP18-2: Design Example for Analytical Modeling of a Curtainwall and Considering the Effects of Bridging (All-Steel Design Approach)” illustrates how to apply the provisions in AISI S100-16, North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition in a practical example by analytically modeling a curtainwall and considering the effects of bridging. The modeling procedure may also be applicable to other framing systems. The example uses two software packages, MASTAN2 (a structural analysis program) and CUFSM (a cold-formed steel member finite strip analysis program). The input data used in the example can be downloaded via the link provided in the research report.
