Document Type: Proceeding Paper

Part of: Seismic Engineering: Research and Practice


The 1988 Uniform Building Code has seen a significant change in the seismic design requirements, Chapter 23, for the design of structures subjected to earthquake loads. This paper discusses what effect these changes and new regulations have on the design of masonry structures. It reviews Chapter 23, General Design Requirements, and Chapter 24, Masonry. A major departure from previous codes for seismic design is the establishment of a resistance factor. Chapter 24 now has much better organization in which it gathers together in one area the topics that are pertinent. These subjects are materials, construction, quality control, allowable stresses, and design. Outlined in this paper are the major changes that have been put into effect for the 1985 code and are in effect in the 1988 code for masonry design and construction.
