PROGRESSIVE COLLAPSE PREVENTION OF DRIVE-IN STEEL STORAGE RACKS

Abstract: Unlike residential and commercial buildings, a more effective and rational approach to preventing progressive collapse in storage racks is to sacrifice the bay where a local failure initiates. The cost of a confined collapse of one bay is insignificant compared to the cost of a progressive collapse. This paper investigates the use of fuse connectors between the portal beams and the uprights of typical drive-in steel storage racks for preventing a local collapse in a bay from propagating to adjacent bays. Through nonlinear dynamic analysis, it identifies the topology and conditions where fuse connectors may be effective.

Dr. Lip Teh is a Senior Lecturer in civil engineering at the University of Wollongong, Australia. He received his Bachelor of Engineering in combined civil and mining engineering from the same university, and his PhD in structural engineering from the University of Sydney. He was a senior structural engineer with a former division of Siemens when he joined academia 5 years ago. He is a co-author of the Guidelines for Direct Second-order Inelastic Analysis of Steel Frames published by the American Society of Civil Engineers, and an editorial member of the Guide to Stability Design Criteria for Metal Structures sponsored by the Structural Stability Research Council USA. A number of his papers have led to new design procedures in the steel design standards in Australia and North America. He is an associate editor of ASCE Journal of Structural Engineering, and is a member of two new committees on cold-formed steel and on structural steel. His current emphasis is on research topics that are likely to lead to useful applications in the real world, including bolted connections, climate resilient structures, modular construction, progressive collapse, retrofitting and strengthening of steel structures.
