Diagram showing the embedded parts, Diagram openings, grooves for foundation bolts, etc. openings, Nature of soil and its static and dynamic Nature properties as required in design calculations. properties PERMISSIBLE AMPLITUDES PERMISSIBLE The permissible amplitudes are generally specified by the The manufacturers of machinery. The permissible amplitude of a machine foundation is governed by the relative importance of the machine and the sensitivity of neighboring structures to vibration. neighboring For foundations of sensitive equipment such as calibration For test stands and precision machines, the design criteria should be established either by the user or equipment manufacturer. For such installation in which the equipment itself is not the source of vibration, it is necessary to evaluate the ambient vibrations at the site and provide suitable isolation in order to contain the amplitudes of movement within acceptable limits. within...
