Statybinių konstrukcijų jungčių įtaka vibracijų silpimui

Abstract

The thesis consists of general characteristics, list of notations, introduction, four main chapters, general conclusions and list of references. In the Chapter 1 classification of noise in buildings, features of structure-borne sound transmission and calculation of sound transmission in buildings methods were briefly outlined. Chapter 2 presents a survey of the scientific literature related to modeling of sound transmission at joints in building constructions, concentrating on semi-infinite plate joints model based on SEA theory. Chapter 3 presents a calculation model of vibration attenuation at semi-infinite plate joints based on SEA theory background and equations of classical bending wave theory. In Chapter 4 a calculation model of vibration attenuation at complex plate-beam joints based on SEA semi-infinite plate theory model is presented. In Chapter 5, the influence of geometrical and physical parameters on the symmetric and asymmetric joints of plates, and the influence of geometrical parameters on the joints of plates and column were defined.
