THE DYNAMIC LOADING TESTS ABOUT ARM - OVER DROP PIPING OF SPRINKLER

A study on seismic retrofit and renovation of building equipment and non-structural elements Part 2

Abstract

If an earthquake occurs, damage to sprinkler piping, thus need to be kept in working order, can lead to secondary damage such as water leaks, making it difficult for the building to be used. Therefore, a refurbishment plan need understanding the seismic performance around the sprinkler head and arm-over drop piping of sprinkler. So, this study what shaking table tests about flexible piping. It grasped vibration characteristic from vibration, and the effectiveness of the arm-over drop piping in shaking table tests, response value of the piping for structural frame with vibration characteristics, the basic date for the numerical analysis.
