This lesson will review the basics of masonry construction so that those observing or accessing that construction are aware of common procedures and practices. Tolerances of units and construction will be reviewed so that those constructing masonry, or judging that construction know whether the resulting work is reasonable and within common tolerances.…
This lesson is designed to provide a thorough understanding of grout for new masonry construction, especially as it pertains to the responsibilities of a Special Inspector. It describes the purpose of grout for masonry construction, both fine and coarse, as well as conventional and self-consolidating mixes, and desirable properties for all of these. It…
This lesson is designed to provide a thorough understanding of mortar for new masonry construction, especially as it pertains to the responsibilities of a Special Inspector. It describes the purpose of mortar joining masonry units and the desirable properties of fresh and hardened mortar.…
This lesson will review common types of reinforcement, ties and anchors used in masonry along with requirements on their manufacture and use while discussing which ones are preferred and why.

Get all 9 Special Inspection of Structural Masonry lessons at a discounted rate when buying the Special Inspection of Structural Masonry bundle.…
This lesson will review the basics of masonry unit production and properties with a specific focus on those items inspectors and construction personnel would need to know about or confirm. Common concrete masonry units and clay masonry units will be discussed, along with key differences in these materials.…
This lesson provides an overview of why special inspection of masonry is required, what needs to be inspected, and how often inspection is typically provided based on requirements in various codes, standards, and guides. Basic special inspection requirements for various masonry tasks are reviewed, and expectations on a special inspector are discussed.…
This lesson reviews the behavior and load distribution of a lintel within a wall, to help design this common element more effectively and efficiently. Lintel design basics will be reviewed, including possible arch analysis, code requirements specific to lintels, design criteria, and the various options we have in selecting lintels in masonry walls.…
Chapter 12 of the TMS 402 2016 includes provisions for the design of anchored and adhered masonry veneer. Although the vast majority of anchored masonry veneer systems are designed using the prescriptive provisions within this standard, veneers in high wind zones, high seismic zones, or constructed with large distances between the backing walls and the veneer cannot be designed using these prescriptive provisions.…
Façade inspections are critical to building enclosure performance and integrity. Discover the best practices in façade inspections through the use of The Masonry Society’s “Guideline for Masonry Façade Condition Assessment” (TMS-1700-17). See examples of how to conduct a façade inspection on an existing building with photos of actual conditions in the field.…
This lesson addresses the movement characteristics of masonry wall systems, and compares the differences between architectural veneer and structural reinforced masonry. Focus is on best practice for design and construction of expansion and control joints to accommodate and/or restrict masonry material movement.…
After selecting masonry as a system for a project, a designer is faced with many choices of materials. For mortar and grout, one of the key ingredients is cement. With so many cementitious products available in the market, it can be difficult to know which ones are right for your project.…
The design of reinforced masonry shear walls using both the Allowable Stress Design method and the Strength Design method is covered in this lesson. The requirements for both the design for overturning and the design for shear are explained. The prescriptive seismic detailing requirements for each of three reinforced masonry shear walls types, ordinary, intermediate, and special, are explained, with particular attention to special reinforced shear walls.…
Proper testing of masonry products is essential to ensure that materials meet project requirements. There are many mistakes that can be made during product testing, and most of these mistakes can lead to jobs being delayed or stopped, and usually require costly follow-up to determine if there are problems with the resulting construction.…
There were two major changes to the anchor bolt design provisions in the 2016 edition of TMS 402. One change was to increase the calculated shear crushing strength by 67%. The other change was to go from a linear interaction equation for combined bending and shear to an elliptical interaction equation. …
Sustainable design and green building are ever evolving. LEED version 4, introduced in late 2013, contains significant changes in the area of Materials and Resources. Masonry expert, Christine A. Subasic, P.E., LEED A.P., provides an overview of the LEEDTM v4 Rating System. This…
Special inspection is increasingly being required on structural masonry construction projects, and it will likely become commonplace in the coming years. Minimum requirements for Special Inspection and Quality Assurance of masonry recently were updated and modified in TMS 402/602-16. This lesson will overview special inspection, review changes, and highlight key inspection tasks.…
Nondestructive evaluation methods are valuable approaches for evaluating conditions of existing masonry construction without causing damage. Masonry strength can also be measured in place using in situ test methods, without resorting to destructive sample removal for laboratory testing. Methods discussed during this lesson include mortar hardness testing, pulse velocity measurements, surface penetrating radar, infrared thermography, flatjack testing, and in situ shear tests, with special emphasis on applying these methods for diagnosing both historic and modern masonry construction.…
Achieving energy code compliance is becoming increasingly more difficult using the code prescriptive methods. Whole building analysis is one alternative method that will produce more cost effective designs for exterior masonry assemblies. This lesson provides an overview of energy code provisions, reviews energy studies performed utilizing whole building analysis, and provides recommendations for cost effective energy efficient solutions for energy efficient exterior masonry wall designs.…
Strength design was added to TMS 402 Building Code Requirements for Masonry Structures in 2002. However, most masonry is still designed by the Allowable Stress Design method. Strength design generally results in more efficient designs than with Allowable Stress Design. This lesson reviews the design assumptions for strength design, and look at the design of beams, bearing walls, and shear walls using strength design.…
The TMS 402/602-16 (formerly designated as TMS 402/ACI 530/ASCE 5 and TMS 602/ASCE 530.1/ASCE 6) has been released and adopted by the 2018 edition of the International Building Code and International Residential Code for the design and construction of structural masonry, masonry veneer, and glass unit masonry.…
