Chapter 12 dictates which lateral force-resisting systems are permissible for a given Seismic Design Category. It provides height limits for different systems. For example, an "Ordinary Masonry Shear Wall" may be unlimited in height in Seismic Design Category A but prohibited in Seismic Design Category D.
Understanding the seismic provisions within the ASCE 7-05 PDF is essential for engineers, architects, and building officials dealing with legacy structures or studying the evolution of seismic code requirements. Core Components of Seismic Design in ASCE 7-05 asce 7-05 seismic pdf
