This book was released on 2015-12-28 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structural control techniques are widely recognized as an effective means to reduce the response of inadequately damped systems. Its applications ranges from small rotating machines to large civil engineering structures subjected to earthquake or wind loading. Buildings and bridges that have been constructed using structural control shows that it is a valuable and promising engineering tool. The present research work mainly consists of two parts. In the first part of the study, harmonic and seismic response of the single-degree-of-freedom (SDOF) structure to which a passive and semi-active tuned mass friction damper (TMFD) is attached is investigated. Second part of the study focuses on the investigation of effectiveness of multiple tuned mass friction dampers (MTMFD) over a TMFD; here response of the multi-story structure and the bridge with TMFD is compared with response of the same structures with MTMFD. This study is intended to provide an insight to the feasibility of potential application of these devices in vibration control of structures and bridge.

Available in PDF, EPUB and Kindle. Book excerpt: Authors: Hugo Bachmann, Walter J. Ammann, Florian Deischl, Josef Eisenmann, Ingomar Floegl, Gerhard H. Hirsch, Günter K. Klein, Göran J. Lande, Oskar Mahrenholtz, Hans G. Natke, Hans Nussbaumer, Anthony J. Pretlove, Johann H. Rainer, Ernst-Ulrich Saemann, Lorenz Steinbeisser. Large structures such as factories, gymnasia, concert halls, bridges, towers, masts and chimneys can be detrimentally affected by vibrations. These vibrations can cause either serviceability problems, severely hampering the user's comfort, or safety problems. The aim of this book is to provide structural and civil engineers working in construction and environmental engineering with practical guidelines for counteracting vibration problems. Dynamic actions are considered from the following sources of vibration: - human body motions, - rotating, oscillating and impacting machines, - wind flow, - road traffic, railway traffic and construction work. The main section of the book presents tools that aid in decision-making and in deriving simple solutions to cases of frequently occurring "normal" vibration problems. Complexer problems and more advanced solutions are also considered. In all cases these guidelines should enable the engineer to decide on appropriate solutions expeditiously. The appendices of the book contain fundamentals essential to the main chapters.

This book was released on 2023-09-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work considers dampers that do not solely focus on a single strategy but instead combine them. The capabilities of conventional dry friction dampers are expanded by taking into account piecewise defined contact geometries. This leads to friction dampers that change their behavior depending on the amplitude of the oscillations. The vibration damping device in this work, introduces damping at high oscillation amplitudes and takes advantage of absorption at low oscillation amplitudes.

Available in PDF, EPUB and Kindle. Book excerpt: Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan. Written by a world renowned author and educator Seismic design and retrofitting techniques for all structures Tools improve current building and bridge designs Latest methods for building earthquake-resistant structures Combines physical and geophysical science with structural engineering
Download or read book Semi active Control of Air suspended Tuned Mass Dampers written by Fahad Abdulrahman Alhujaili and published by . This book was released on 2012 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive studies have been carried out, in recent years, to find methods to mitigate the unwanted structure vibration caused by human excitation, machinery, and winds. Modern structures such as floors and bridges using high strength materials, and extending across long spans are very flexible with negligible damping. Vibration control devices and strategies are constantly being developed to eliminate/dissipate the unwanted vibration and to increase the serviceability level of such structures. One such method for abating the vibration is tuned mass damping. In this dissertation, semi-active control of air-suspended tuned mass dampers with pendulum configuration was explored. A novel semi-active Air Sprung PTMD was designed, built, and evaluated, analytically and experimentally. The dynamics and control of such PTMD were evaluated, and its effectiveness was compared with that of the conventional passive PTMD. The main reason for introducing semi-active control to a TMD is to enable the TMD to adapt itself, robustly, to the primary structure's parameters (mainly mass and stiffness) changes and maintain its tuning. Following extensive analytical work, simulation, and experimentation it was found that the velocity feedback can modify the stiffness of the semi-active air-suspended tuned mass damper. Positive velocity feedback increases the stiffness while negative velocity feedback decreases it. Moreover, pressure and the acceleration feedback adjust the damping of the semi-active TMD. The air spring used in this work is of convoluted type. This type of air springs, because of their particular geometry, experiences a rather severe change in their cross-sectional area, as they contract and expand. It was found that to properly account for the impact of this important parameter on the inner-working of the air spring, one needs to consider two areas for the air spring, namely, the effective area and the geometric area. The effective area of the air spring is the area used to calculate the exerted force by the air spring while the geometric area is the cross-sectional area used to calculate the rate of change of the volume of the air enclosed in the air spring. The use of these two areas resulted in an accurate model of the air spring. The model of the semi-active PTMD was verified using the experimental setup. Both the simulation and experimental demonstrate the effectiveness of the semi-actively controlled air-suspended PTMD in adjusting its tuning frequency as well as damping.
