Abstract:
Twisted steel micro reinforcement has been successfully applied by Helix Steel in tens of thousands of structural elements over the last two decades, by using a simple elastic design approach based on a nearly forgotten chapter of ACI 318 for mild structural applications. The approach, outlined in ICC-ES AC 470, leverages these easy to understand concepts together with performance testing to deliver safe and effective designs for mild structural elements including structural slabs on ground, foundations, walls and composite metal deck. We will review the designs and results of applications in 1) above grade walls subjected to high wind loads 2) basement walls subject to saturated soil loads, 3) column and strip footings and 4) composite slab on metal decks. Learning Objectives: 1. Understand the simplicity, utility and limitations of linear elastic design approaches currently available in ACI codes 2. Learn how to apply research reports to demonstrate code compliance through IBC/IRC 104.11 3. Understand design in real word applications in above/below grade walls, footings, and slabs on metal deck 4. Describe the value of the elastic design approach in real word applications in above/below grade walls, footings, and slabs on metal deck.
