Seismic Design of Wood and Masonry Buildings

Abstract

The purpose of this chapter is to present criteria and example problems of the current state of practice of seismic design of wood and reinforced masonry buildings. It is assumed that the reader is familiar with the provisions of either the Uniform Building Code (UBC), Building Officials and Code Administrators (BOCA), or Southern Building Code Congress International (SBCCI), or international code council, international building code (IBC). For consistency of presentation the primary reference, including notations and definitions, will be to the UBC 97. Included within the presentation on diaphragms are criteria and example problems for both rigid and flexible diaphragms. Also included is the UBC 97 criteria for the analytical definition of rigid versus flexible diaphragms. Wood shear walls and the distribution of lateral forces to a series of wood shear walls is presented using Allowable Stress Design (ASD). Masonry slender walls (out-of-plane loads) and masonry shear walls (in-plane loads) are presented using Load and Resistance Factor Design (LRFD).
