Simplified Dynamic Analysis of High-rise Buildings - Hideo Takabatake Yukihiko Kitada Izuru Takewaki Gebunden

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 sediment ary 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.
