Experimental Study on Structural Behaviour of Steel Wire Mesh under Impact Loading

In view of application to debris flow/rockfall barrier system, several types steel wire mesh were selected verify their basic behaviour under impact load free fall weight at the controlled testing environment an in-house facility capable dropping a heavy on approximately 1-meter square panel made such material. Out 3 tested, high-performance chain link endured highest energy, while newly developed showed high potential effectively absorbing energy by its plastic deformation along total length components. Both above two are expected be applied in flexible type flow catchment system combination with larger opening as ring net. The consisting spirally deformed wires behaved energy-absorbing elements transmitting supporting ropes own length.
