Download or read book Measurement of Creep induced Change of Dynamic Stiffness of Resilient Materials Used for Impact Sound Isolation in Floating Floors written by Tongjun Cho and published by . This book was released on 2012 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The creep-induced change of the dynamic stiffness of resilient materials used in vibration isolation systems in floating floors is an important issue, especially with regard to the use of open cell resilient materials, because the change in the dynamic stiffness is a key factor in the performance of vibration isolators, and open cell materials are vulnerable to creep deformation. This study proposes a method for measuring the creep-induced change of the dynamic stiffness that employs quasi-static mechanical analysis under the assumption that the creep-induced change of the mechanical structure of the resilient material is independent of time and stress. The pre-creep dynamic properties of a sample resilient layer measured with a method very similar to the one recommended in ISO 9052-1 are compared with the data measured with the proposed method, and the results illustrate the consistency in the data measured with the two methods. A proposed creep test is performed for a sample resilient layer including open cell material used for a floating floor, and the change in the dynamic stiffness due to creep deformation is assessed by combining the proposed method and the creep test data. The study indicates that the proposed method is able to assess the creep-induced change of the dynamic stiffness and could be useful for the design of vibration isolation systems in long-term use.

Download or read book Structural Vibration written by C. Beards and published by Elsevier. This book was released on 1996-05-31 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many structures suffer from unwanted vibrations and, although careful analysis at the design stage can minimise these, the vibration levels of many structures are excessive. In this book the entire range of methods of control, both by damping and by excitation, is described in a single volume.Clear and concise descriptions are given of the techniques for mathematically modelling real structures so that the equations which describe the motion of such structures can be derived. This approach leads to a comprehensive discussion of the analysis of typical models of vibrating structures excited by a range of periodic and random inputs. Careful consideration is also given to the sources of excitation, both internal and external, and the effects of isolation and transmissability. A major part of the book is devoted to damping of structures and many sources of damping are considered, as are the ways of changing damping using both active and passive methods. The numerous worked examples liberally distributed throughout the text, amplify and clarify the theoretical analysis presented. Particular attention is paid to the meaning and interpretation of results, further enhancing the scope and applications of analysis. Over 80 problems are included with answers and worked solutions to most. This book provides engineering students, designers and professional engineers with a detailed insight into the principles involved in the analysis and damping of structural vibration while presenting a sound theoretical basis for further study.Suitable for students of engineering to first degree level and for designers and practising engineersNumerous worked examplesClear and easy to follow

Download or read book Twentieth Century Building Materials written by Thomas C. Jester and published by Getty Publications. This book was released on 2014-08-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

Download or read book 200 Science Investigations for Young Students written by Martin Wenham and published by SAGE. This book was released on 2000-12-13 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book enables teachers to develop a complete range of basic investigations for science with students aged five to 11 years. It demonstrates how children can use hands-on activities to consolidate and extend their knowledge and understanding. Investigations are presented in a generic form, so that teachers can work through them and adapt them to meet the particular needs of their own classes. The presentation of activities ranges from highly-structured sequences of instructions and questions (with answers!), to more general discussions, depending on the approach needed and the likely variations in equipment and materials available. Each activity is aimed to help any teacher carry out significant scientific investigations with their class, and where necessary, to learn alongside them. - Almost every investigation and activity has been tested by the author. - Investigations use readily-available, non-specialist or recycled materials. The context of this book is children′s need to learn through first-hand experience of the world around them. This book is an essential resource for teachers planning an effective science programme, or for student teachers needing to broaden their scientific knowledge and understanding. 200 Science Investigations for Young Students is the companion volume of activities which demonstrate the theories in Martin Wenham′s Understanding Primary Science. The content has been guided by, but not limited to, The National Curriculum 2000 and the Initial Teacher Training Curriculum for Primary Science, issued by the Teacher Training Agency.
