Preliminary Theoretical and Numerical Investigation of Shock Absorbers in the Safety Nets for Accidental Fall of Heavy Ceilings

Abstract

The ceiling fall occurs one after another, so we must take measures against it. Fall prevention nets are effective measures as a fail-safe, but there are some problems, such as the difficulty of calculation about impact force and how to lighten the load of cables. In this review, we suggest that the shock absorbers which are attached to the ends of cables and lighten the axial force of them are introduced into fall prevention nets for ceilings. We also show the result of numerical analysis of cable nets with shock absorbers in order to reveal the effect of them.
