Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...
In Situ Tests for Foundation Vibrations
There are several well established methods of determining shear modulus in situ and these are summarized in this paper. New techniques are being developed for in situ determination of...
The Rx for Relief from Equipment Failure
A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data...
Available Compaction Equipment
When discussing available compaction equipment we must keep in mind the purpose of compaction. Compaction is the art of artificially increasing the density or increasing the unit weight...
Equipment Requirements for Concrete Recycling
Concrete recycling projects have been completed in a number of states. As the transportation infrastructure ages, concrete recycling will become a common construction operation. Concrete...
A BEM-Perturbation Technique for Membrane Structures
Most of the previous work has concentrated on the free vibration problem. The present paper examines the problem of low frequency forced vibrations of a membrane due to an oscillatory,...
Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...
Some Applications of Fourier Series in Structural Optimization
This paper discusses the application of the method of truncated Fourier series to problems of structural optimization. It begins with a discussion of the range of the method which has...
An Integrated Approach to Structure and Control Design of Space Structures
In this paper the authors have investigated the effect of passive damping on the optimum structural design with active controls. The minimum weight design is obtained by imposing the constraints...
