We present an evaluation of the potential improvements in seismic disturbance rejection obtained by using active variable damping control in a structure. Using the response to seismic excitation of an optimally controlled variable structure and of a minimax optimally designed fixed structure, we obtain an upper bound on the achievable performance and a lower bound on the acceptability of a control system for a variable damping structure. Our numerical experiments suggest three conclusions. (1) A minimax optimal designed structure gives very good seismic disturbance suppression, not only for the earthquakes used in its design, but also for other earthquakes of similar intensity. (2) The use of variable structure control is not likely to result in smaller maximum interstory drifts than exhibited by a fixed minimax designed structure. (3) The gap between the upper and lower bounds is rather small, which makes designing a feedback law that results in performance superior to that of a minimax designed structure very difficult. The best choice appears to be in the form of a continuous moving horizon control law, using a horizon of under 0.2 seconds. This requires determination of whether local ground motion can be predicted up to 0.2 sec. ahead, using ground motion monitoring sensors located a small distance away from the site.

Download and read online ebook Seismic Evaluation, Damage, and Mitigation in Structures write by Iman Mansouri. This book was released on 2022-11-30. Seismic Evaluation, Damage, and Mitigation in Structures available in PDF, EPUB and Kindle. Seismic Evaluation, Damage, and Mitigation in Structures covers recent developments in the field of seismic performance assessment of structures. Earthquakes are one of the main natural hazards that can directly cause damage to a structure or even instigate a structural collapse, resulting in significant economic and human loss of life. In the event of an earthquake where many buildings and infrastructure components are not able to function afterward, or if extensive repair and associated disruption are needed, it can be extremely costly and take a long time to resolve. Divided into three parts, this book reviews and discusses earthquake-induced damage evaluation in structures, the repair of structural and non-structural components, and seismic damage mitigation strategies. With contributions from the leading experts in the field, this book is for earthquake engineers, structural engineers, PhD students studying civil engineering, people who can easily inspect and repair structures for quick reoccupation, and for those who understand topics such as design and damage mitigation, and limited structural or non-structural damage in seismic events. Provides effective and economical methods to assess the seismic performance of structures Analyzes earthquake damage and repair or demolition of buildings Offers future needs for constructing seismic resistant structures
