This course provides an overview of resilient design and discusses how resilient design is and is not covered by building codes and standards. The role of masonry construction in meeting resilient design goals is explained, and the inherent properties of masonry that make it resilient are described.…
While masonry is extraordinarily durable, maintenance is required from time to time. Based on inspection and assessments performed, issues may be found that require regular monitoring. Learn about common maintenance for masonry to ensure it continues to serve as intended. Techniques to routinely monitor the condition of masonry, cracks and more will also be discussed.…
Once an assessment is complete and a rehabilitation approach has been selected, implementing the rehabilitation work is the next milestone. Bid documents for rehabilitation projects of traditional masonry wall systems should address two fundamental issues. First, all existing conditions, particularly concealed conditions, are not known and can’t be known until the work begins.…
Once the assessment is complete and the deterioration mechanisms are known, rehabilitation options can be considered. This session introduces rehabilitation options for the transitional masonry wall system to be considered based on deterioration mechanisms, including those related to structural concerns and water management.…
Building on concepts presented during prior sessions, this session discusses approaches for obtaining information on material properties and how to use that information to understand structural capacity following applicable codes and guidelines. Several in situ methods are available for determining masonry mechanical properties including compression and shear strength.…
This session of the existing masonry series focuses on the important aspects of developing an investigation program for a transitional masonry building, including information to gather, areas for inspection, ongoing monitoring, the potential for investigative openings and laboratory testing to inform potential structural analyses to consider.…
This session of the existing masonry series discusses the typical masonry exterior wall systems, commonly referred to as transitional masonry wall systems and how to identify them. These wall systems combine aspects of both load-bearing masonry and modern curtain wall systems having structural frames.…
This session of the existing masonry series reviews masonry materials commonly used in cladding systems between the 1880 and 1945 in North America, including brick, terra cotta, concrete masonry, cast stone, natural stone, and mortar. Common material properties, uses, and deterioration mechanisms will be presented.…
This course reviews US fire statistics, the Balanced Fire Safety Design concept and the role that passive masonry firewalls play in it. Examples of how today’s building codes have eroded the Balanced Design Concept are shared to provide a better understanding of the crucial role fail-safe, passive masonry fire walls play in today’s fire safety designs.
Reinforcement and connectors are essential to ensure a proper load path in masonry buildings. This session will review basic detailing requirements for reinforcement and connectors, and specific requirements for strength design of masonry. Lap length requirements for reinforcement, and design of anchor bolts will be reviewed.…
