This presentation is intended for Structural Engineers that desire to become familiar with Chapter 9 “Strength Design of Masonry” in TMS 402-16 Building Code Requirements for Masonry Structures (Formerly also designated as ACI 530 and ASCE 5). As a 1 hour introduction to this Chapter, this presentation will cover the provisions governing concrete masonry (both reinforced and unreinforced) under combined axial and out-of-plane loading, including examples. This discussion will also introduce the “flat arch” approach to complying with the requirements of TMS 402-16 Section 9.3.1 as permitted in TMS 403-13 Direct Design Handbook for Masonry Structures (referenced by the IBC). At the end, there will be a brief demonstration of the Ensoltech / National Concrete Masonry Association (NCMA) Direct Design 3.0 software, which performs a comprehensive in-plane and out-of-plane analysis and design using Strength Design provisions and automatically generates wall reinforcement elevations.
*Hard copies of TMS 402-16 will be available for purchase at the meeting.*
