dc.description.abstract |
Industrial steel storage pallet racking systems are used extensively worldwide to store goods.
Forty percent of all goods are stored on storage racks at some time during their manufactureto-
consumption life. In 2017, goods worth USD 16.5 billion were carried on cold-formed steel
racking systems in seismically active regions worldwide. Historically, these racks are
particularly vulnerable to collapse in severe earthquakes. In the 2010/2011 Christchurch
earthquakes, around NZD 100 million of pallet racking stored goods were lost, with much
greater associated economic losses due to disruptions to the national supply chain.
A novel component, the friction slipper baseplate, has been designed and developed to very
significantly improve the seismic performance of a selective pallet racking system in both the
cross-aisle and the down-aisle directions. This thesis documents the whole progress of the
development of the friction slipper baseplate from the design concept development to
experimental verification and incorporation into the seismic design procedure for selective
pallet racking systems.
The test results on the component joint tests, full-scale pull-over and snap-back tests and fullscale
shaking table tests of a steel storage racking system are presented. The extensive
experimental observations show that the friction slipper baseplate exhibits the best seismic
performance in both the cross-aisle and the down-aisle directions compared with all the other
base-connections tested. It protects the rack frame and concrete floor from damage, reduces the
risk of overturning in the cross-aisle direction, and minimises the damage at beam-end
connectors in the down-aisle direction, without sustaining damage to the connection itself.
Moreover, this high level of seismic performance can be delivered by a simple and costeffective
baseplate with almost no additional cost. The significantly reduced internal force and
frame acceleration response enable the more cost-effective and safer design of the pallet
racking system with minimal extra cost for the baseplate.
The friction slipper baseplate also provides enhanced protection to the column base from
operational impact damage compared with other seismic resisting and standard baseplates. |
