The performance of steel-frame buildings with infill masonry walls in the 1906 San Francisco earthquake

By: Ronald Hamburger, John Meyer

Abstract: Following the great 1906 San Francisco earthquake and fire, engineers recognized the superior performance of buildings with complete vertical load-carrying steel frames and infill masonry walls. These buildings were noteworthy in their...

Seismic forces in diaphragm design

By: Ronald Mayes, Kevin Moore, Eatherton, Matthew, Naguib, Wassim I, Sabelli, Rafael, Boardman, Tom

Abstract: The 1994 Northridge Earthquake offered several instances of diaphragms and their components performing inelastically and even causing partial collapse, most notably in parking garages. While diaphragm failures are not widespread, it is...

Implementation of Higher Performance Structural Systems in the United States

By: Ronald Mayes

Abstract: The development of more recent structural systems that perform better than standard moment frames, braced frames and shear walls occurred with the introduction of base isolation (1970's and 1980's), energy dissipation devices (...
