Shear walls are critical building elements to resist in-plane loads and are, for masonry, the seismic-force-resisting system. This session of the Strength Design of Masonry series reviews strength design of shear walls, along with both seismic detailing requirements and minimum/maximum detailing requirements for such walls.…
During this session, design of masonry walls loaded with out-of-plane loads and axial loads will be reviewed. Methods to consider secondary bending moments will be examined, including using P-delta provisions, and key points on interaction diagrams will be reviewed. Differences in the strength design provisions and allowable stress design will be briefly discussed.…
This session will review the design of masonry beams and lintels, including an examination of whether arching action can be used to reduce the loads on these elements. Deflection calculations will be reviewed, along with detailing requirements to meet code minimum and maximum reinforcement percentages.…
This introductory session will review basic strength design concepts for masonry, noting key differences with procedures for concrete. Masonry assemblies and systems will be briefly reviewed noting their purposes and resistance to primary loads. Individual masonry elements of masonry buildings including walls, beams, columns, and pilasters will then be introduced, related to their roles in the overall structural system to orient attendees for further sessions where the design of these elements will be discussed.…
This lesson looks at the properties of masonry assemblies based on the how it is constructed and bonded. Structural assembly properties including the modulus of elasticity, modulus of rupture, and compressive strength will be introduced and discussed. Other assembly properties related to dimensional stability, fire resistance and energy performance will also be reviewed, along with resources that can be used for additional information on these topics.…
This lesson provides a comprehensive introduction to grouts and grouting for new masonry construction, especially for those who have little to no experience with masonry but find themselves needing to design or review projects. 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.…
This lesson covers types of reinforcement used in masonry, including bars, joint reinforcement, anchors and ties. Each type of reinforcement will be explored, and the use in masonry will be identified. The basic placement requirements and protection requirements will be covered.…
This lesson provides a comprehensive introduction to mortar for masonry construction, especially for those who have little to no experience with masonry but find themselves needing to design or review projects. It describes the purpose of mortar joining masonry units and the desirable properties of fresh and hardened mortar.…
This lesson introduces attendees to the most common types of masonry units, how they are made, and how they are commonly used. Units covered include concrete masonry units, clay masonry units, natural stone units, manufactured stone veneer units, cast stone units, and AAC masonry units.…
This lesson introduce masonry to the attendees, reviewing basic terminology, acronyms, properties, benefits, and uses of masonry. Essential references that help with the understanding, design and use of masonry will be noted to provide a basis and a source for future learning on masonry.…
