Dear Sir,

Seismic joints are frequently required between adjacent buildings and are often introduced to separate two or more parts of the same building. This paper discusses the use and design issues of seismic joints in buildings, including answering the following questions: • What is a seismic joint? • How have seismic joints traditionally been used? • How do seismic joints differ from expansion joints? • When should seismic joints be used and when not? • Where should seismic joints be located? • How is the appropriate width of the joint determined? • What are the major structural issues with seismic joints? • What are the major architectural and fire issues with seismic joints.
