Experimental Investigation of the Forklift Truck Impact on CFS Pallet Racks

Background: Storage pallet racks are commonly formed by Cold-Formed-Steel (CFS) members and used worldwide to store goods on pallets. The main racking system is denoted as “selective racking”. This one deep separated aisles, allowing for each pallet, stored horizontal beams, be always accessible. Steel systems frequently subjected accidental impact forces from operating forklift trucks. If international design codes provide an arbitrary value of force members, several impacts can produce damages, which lead failure, highlighting the fundamental role played monitoring. Methods: Results experimental campaign a full-size selective rack presented. investigated truck hammer test at different points. propagation acceleration among adjacent bracing frames with magnitude recorded strains in structural members. Results: highlight that accelerometer every two spans establish whether monitored accidentally hit. Compressed diagonal tensile work parallel. Only brace, spans, through strain gauge point estimate stress distribution Conclusion: study suggests optimization number, type position accelerometers gauges monitoring identify its effects.
