340668 - Cold Formed Steel Connections Best Practices

Saturday, April 21
10:00 AM - 11:30 AM
Location: 201C

The proposed session is on a new ASCE-sponsored Design Guide titled ‘Cold-Formed Steel Connections: Best Practices” to be submitted to the review committee by March 2018. Cold Formed Steel is often used as a component and cladding material on many buildings. Therefore it has to connect to the various building materials that the Main Wind Force System was designed from. Cold Formed Steel connections have unique characteristics as they are often required to slip or drift in various directions plus due to the thin material different checks need to be made. The session presentation is going to help the practicing engineer learn how to connect Cold Formed Steel to structural steel, concrete (un-cracked, cracked, post-tensioned), CMU, brick and wood. There will be various design examples shown along with pictures for why engineers need to do the design checks for the connectors and fasteners that are required. The session format will be innovative as it will include audience participation through live text input into the presentation allowing the presenters to cater the presentation to the audience’ needs. As the audience are texting in poll responses or questions, the presenters can help guide them to the correct codes or resources for the design of these connections. In addition, the presenters will be showing portions of the new to be released design guide “Cold Formed Steel Connections: Best Practices” which expected to be published by ASCE in 2018.
