MASON INDUSTRIES SEISMIC RESTRAINT GUIDELINES

These guidelines provide general seismic restraint requirements and details for suspended piping, ductwork and electrical systems. Prior to installation, the support and seismic restraint locations shall be verified by the engineer responsible for the design of the structure… Download

A PICTORIAL STUDY OF SEISMIC DAMAGE

On an early January morning in 1994, the Northridge area of Southern California was shaken by an earthquake that measured 6.6 on the Richter scale and lasted approximately 30 seconds. The repercussions are still being felt throughout the engineering community… Download

SEISMIC SPECIFICATION APPLICATION DRAWINGS

Seismic Applications are basically the same as Non Seismic but complicated by the need to keep equipment in place. Whenever we show our Z-1011 heavily cushioned snubbers, the input to the equipment will not exceed 4 G. All mountings, hanger-cables or snubbers are designed to resist the seismic force in any zone or specification… Download
