The primary seismic force-resisting elements in buildings are horizontal diaphragms, vertical framing elements, and foundations. Together, these elements, comprise the seismic force-resisting system (SFRS). In reinforced masonry structures, the vertical framing elements are generally structural walls. They resist out-of-plane loads from wind or earthquake and transfer those loads to diaphragms and foundations. They also resist in-plane loads received from diaphragms and convey them to foundations. Given the wide variety of masonry materials, forms, and local construction practices, many kinds of reinforced masonry structural walls are possible. This course focuses on the design of one classification of walls for one loading case: special reinforced masonry shear walls subjected to in-plane seismic and gravity loads.

This course is intended especially for the practicing structural engineer, although it will also be useful for building officials, educators, and students. Although it emphasizes code requirements and accepted approaches to their implementation, it also identifies good practices that go beyond the minimum requirements of the building code. Background information and illustrative sketches clarify the requirements and recommendations.

Following the introduction, Sections 2 and 3 describe the use of structural walls in buildings and discuss intended behavior of these walls. Section 4 provides analysis guidance. Section 5 presents the design and detailing requirements of TMS 402 along with guidance on how to apply them. Section 6 presents additional requirements that must be considered for all masonry buildings, particularly those assigned to SDC D, E, or F. Section 7 addresses detailing and constructability challenges for special structural walls.
