As in VCS-100, we have designed the specification to be written in tabular form. Your specification book would contain all the verbiage in pages 1 through 24. We realize this complete specification is quite long, but providing proper protection is not a simple issue. It is always your option to abbreviate sections, but we have…
INTRODUCTION TO SEISMIC VIBRATION CONTROL SPECIFICATIONS FOR OFFICE BUILDINGS, COLLEGES, HOSPITAL, THEATERS AND SIMILAR STRUCTURES To The Specifying Engineer: Our company started calling on West Coast engineering firms as early as 1960. We opened our L.A. sales and applications office in 1965 when it became important to provide local service to the most seismically active…
DISCUSSION The very term ‘vibration isolation’ suggests the use of resilient materials between a structure and a machine. The classic model is a mass on top of large coil springs located near the four corners, as in Figure 1. While this is a perfectly practical system for vibration control, when dealing with earthquakes we must…
Sound & Vibration Earthquake control of resiliently mounted systems is an area of primary concern for acoustical and mechanical engineers. The Northridge, CA earthquake of January 17th, 1994, provided several valuable lessons regarding protection of these systems. The lessons learned from this earthquake are highlighted with actual site photographs that are useful and dramatic. The…
