Features: This book is part of the "Brief Civil Engineering Series." Based on the introduction of the basic theory and vibration control design methods of engineering structures, it combines China's codes and focuses on the dynamic characteristics of high-rise buildings with steel towers on top, which have emerged in China in recent years. Using elastic dynamic analysis as the foundation, it analyzes the factors affecting the seismic action on high-rise steel towers, converts them into parameters for analysis—mass, stiffness, and height—and identifies the influence patterns of these parameters on seismic amplification coefficients. It proposes a simplified calculation method for the structural system of high-rise buildings with steel towers. In terms of engineering applications, two case studies are selected to provide detailed calculation methods for the overall damping ratio, vibration control calculation and design, and the effect of the tail effect of the combined structural system. This book can serve as a reference for graduate students and university teachers in civil engineering, as well as for structural designers and researchers engaged in seismic and vibration control.
