DESCRIPTION - summary of the module content

This module will provide you with basic knowledge and understanding relevant to vibration engineering of large civil engineering structures. Particular emphasis will be given to theoretical concepts of single- (SDOF) and multiple-degree-of-freedom (MDOF) systems which form foundations of general structural dynamics for dealing not only with vibration, but also wind, blast and impact engineering disciplines. The module will then focus you on specific problems of environmental vibrations affecting serviceability of structures occupied and dynamically excited by humans (floors, footbridges and grandstands) or by ground borne vibrations due to over and underground traffic, construction and blasting. Methods and tools used routinely for measuring and analysing vibration signals from these structures will be described.

AIMS - intentions of the module

To develop concepts of SDOF and MDOF systems and apply them to real life vibration serviceability problems.
