Shear walls are critical building elements to resist in-plane loads and are, for masonry, the wind and seismic-force-resisting system. This session reviews Allowable Stress Design of shear walls along with both seismic detailing requirements and minimum/maximum detailing requirements for such walls.…
Allowable stress design of masonry walls loaded with out-of-plane loads and axial loads are reviewed. Differences in the Allowable Stress design provisions and strength design procedures will be briefly discussed, especially the secondary bending moments.
Learning Objectives:
This course reviews allowable stress design of masonry beams and lintels and provides an examination of whether arching action can be used to reduce the loads on these elements. Deflection calculations are reviewed, along with code compliance requirements relating to reinforcement and grouting.…
This introductory course reviews basic allowable stress design concepts. Dr. McGinley presents key differences between allowable stress design and strength design procedures. This session also reviews masonry assemblies and systems, noting their purposes and resistance to primary loads. Attendees will learn about typical masonry building elements and their roles in the overall structural system including walls, beams, columns, and pilasters.…
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.…
