About The past three years have been witness to significant changes to the design codes and standards addressing concrete masonry construction. Included in these changes are revisions to ASTM C90 for load bearing concrete masonry units that incorporates new options to allow units to be reconfigured to make the unit more energy efficient, lighter, and more versatile to meet project requirements. Additionally, based on research, the masonry design standard (TMS 602/ACI 530.1/ASCE6) was The Next Generation of Concrete Masonry NXGN-DL / 2015 modified to recalibrate the unit-to-assembly compressive strength correlation provisions. The net result was a baseline increase of about 33% on design strengths – without any changes to the materials or design methodology. The new changes, benefits, and opportunities with these new requirements will be reviewed. Presented by Jason J. Thompson, Vice President of Engineering of the National Concrete Masonry Association. October 18 11:00 AM Lunch included The Foundry 747 World’s Fair Park Drive Knoxville, TN 37902 RSVP - Learning Objectives Learning Units -1 Credit Designations - LU/HSW Understand recent changes to ASTM C90 for web requirements and compressive strength. Discuss the benefits and opportunities for improving energy efficiency and other properties of concrete masonry assemblies using modified web configurations. Understand research that was conducted to justify changes to Unit Strength Method for compliance with specified compressive strength of masonry in Specification for Masonry Structures. Evaluate how increasing the base design strength of concrete masonry assemblies can lead to more efficient structural design.
