Retrofitting existing tanks with flexible expansion joints offers immediate and relatively economical benefits when seismic upgrading is necessary. The addition of flexible tank connections is easily justified in the design of new installations. This paper will discuss the application and advantages of such connections.
Numerous studies have been conducted on the response and survivability of liquid reservoirs subject to seismic shaking. A common mode of failure is depicted in nearly every account, failure of the storage structure due to failure of a rigid connection. In many cases the tank connection was made with flanged cast gray iron fittings bolted to other flanged appurtenances and subsequently to flanged piping leading underground. This type of system allows no freedom of motion. During seismic shaking, one or more of the flanges or fittings is almost certain to fail.
