Integrated floor vibrations on concrete and composite concrete floor
ISBN: 9783659161902 / Angielski / Miękka / 2012 / 628 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book is about concrete floor and development a composite concrete floor, measure vibration serviceability. Composite structures are created as a result of connecting two or more structural components, which are often made from materials with various properties. Composite concrete floors, used in civil engineering, are typical example of such structures. Structures of this kind are usually used as elements of floors in general and industrial building. This book covers introduction, literature review and experimental analysis of such kind of floors.

Floor Vibration: A Discussion
ISBN: 9783845415802 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This Book concerns floor vibration, describes the nature of floor vibration and provides options for avoiding it through design, or in the case of existing buildings, reducing or eliminating it through alterations. Excessive floor vibration has become a great problem as new rhythmic activities, such as aerobics, generators, air conditioners and long-span floor structures have become more common. The current push towards stronger concrete materials and the use of prestressing results in increasing fineness and dynamism of long-span concrete floors in buildings. Although concrete floors have a...

Materials and Methods for Concrete and Composite Conrete Floor
ISBN: 9783847338215 / Angielski / Miękka / 2012 / 164 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book outlines an extensive and elaborated experimental work to attain the objectives set in the thesis. The material properties of concrete, profiled steel (PSF) and vibration damping compound (VDC) are investigated in the laboratory to carry out the theoretical calculation of this study. For the prediction of time-dependent deflections of floors, compressed test of concrete were conducted in the laboratory. The experimental work is divided into two groups. In the first group, the dynamic performance (acceleration, force, and damping) of floors are investigated. The second group of...

Suppression of Random Vibration in Concrete& Composite Concrete Floor
ISBN: 9783848425396 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A composite concrete floor is proposed in this book to suppress stationary random vibration in concrete structures using a compound vibration absorber named vibration damping compound (VDC). While the traditional vibration absorber can damp down the vibration mainly at the pre-tuned mode of the primary structure, active damping is generated by the proposed VDC to damp down all resonant modes of interest of the vibrating structure and the spatial average mean square motion of the vibrating structure can be minimized. Only one absorber and one feedback signal are required to achieve vibration...

Effects of Vibrations on Concrete Floor and Composite Concrete Floor
ISBN: 9783846540107 / Angielski / Miękka / 2012 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The generation of the impact sound by the act of the human walk involves two factors, the character of the footfall and the shape of the induced floor vibration. High levels of vibrations can occur in floor systems due to excitation from human activities such as walking and aerobics. In building floors, excessive vibrations are generally not a safety concern for building floor system but a cause of annoyance and discomfort. The footfall noise is created by the impact excitation where the character of the footfall depends on the foot-ware: the heels and the frequencies of the footfall. The...

Vermicompost and Npk on Wheat
ISBN: 9783846592113 / Angielski / Miękka / 2012 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A field experiment was done at SAU Farm, in winter(10 Nov. 2004-07 Mar.2005)to investigate the effect of vermicompost and NPK (Nitorgen+Phosphorous+Potassium) on the growth, chemical composition and yield of wheat. The experimental soil was silty clay, pH 6.0. The treatments were 4 levels of vermicomposts viz. V0 (0 t ha-1), V1 (1 t ha-1), V2 (2 t ha-1), V3 (3 t ha-1), and 4 levels of fertilizers viz. F0 = (0-0-0 kg ha-1), F1 = low (40-30-20 kg ha-1), F2 = medium (80-60-40 kg ha-1), F3 = high (120-80-60 kg ha-1) of N-P2O5-K2O with 16 treatments combinations and 3 replications. The results...
