Abstract:

Over the past decade the capabilities for vibration measurements and analysis have advanced significantly. It is now a routine procedure to be able to measure natural frequencies of structures and equipment in the field. In cases where foundation soils are involved, their dynamic properties are routinely measured as well. With this increased capability of being able to define the problem, it is now possible to arrive at better solutions. Once a solution is provided, however, it is not uncommon for the owner not to implement it if no damage has occurred. In these cases the owner has decided to live with the problem. When the recommended solution is implemented the verification measurements are usually minimal if significant reductions in vibration occur. It is this data however that provides the evaluation of the effectiveness of the solution and efforts should be undertaken to place greater emphasis on this phase of the problem. The papers in this book deal with spectator induced vibrations, and machinery induced vibrations. In each case a problem of high vibration is identified and solutions for the reduction of vibration are presented.
