SIMPLIFIED DYNAMIC ANALYSIS OF HIGH-RISE BUILDI...

This book presents a simple analytical method based on the extended rod theory that allows the
earthquake resistance of high-rise buildings to be easily and accurately evaluated at the
preliminary design stage. It also includes practical software for applying the extended rod
theory to the dynamic analysis of actual buildings and structures. High-rise buildings in large
cities  built on soft ground consisting of sedimentary rock  tend to have low natural
frequency. If ground motion due to an earthquake occurs at distant hypocenters  the vibration
wave can be propagated through several sedimentary layers and act on skyscrapers as a
long-period ground motion  potentially producing a resonance phenomenon that can cause severe
damage. Accordingly  there is a pressing need to gauge the earthquake resistance of existing
skyscrapers and to improve their seismic performance. This book was written by authors who have
extensive experience in tall-building seismic design in Japan. The software included enables
readers to perform dynamic calculations of skyscrapers' resistance to vibrations. As such  it
offers a valuable resource for practitioners and engineers  as well as students of civil
engineering.
