Abstract

Steel pallet rack frames stabilized by single-sided spine bracing are efficient structural systems in that they commonly carry a large number of pallets while utilizing only limited footprints. This research experimentally establishes the global buckling behavior of the steel pallet racks under vertical loads and stabilized by single-sided spine bracing. A total of eight rack frames are involved in the test program. The test setup was designed to achieve realistic loading conditions at all times. The research explicitly considered the various types of commonly used spine bracing configurations and upright frame bracing configurations in industrial practices, and generated comprehensive test data. The experimental observations suggest that the pallet rack frames stabilized by single-sided spine bracing exhibit combined translational and torsional sway motions under vertical loads, and fail by a global three-dimensional buckling of the entire frame. The investigation established that the effectiveness of down-aisle spine bracing is compromised by the rack-to-spine-bracing connections, and the strength of the global rack frame is intertwined with the stabilizing force transfer mechanism between the main rack frame and the spine bracing. The transverse shear stiffness of the upright frames in the cross-aisle direction plays a key role in determining the global torsional performance and strength of the rack frames. Recommendations for the design of pallet racks stabilized by single-sided spine bracing are proposed.

通过单侧脊柱支撑加固的钢制托盘货架框架是一种高效的结构系统，因为它们通常可以承载大量托盘，同时只占用有限的空间。本研究通过实验确定了钢制托盘货架在垂直载荷作用下的整体屈曲行为，并通过单侧脊柱支撑进行了稳定。测试项目共涉及八个货架框架。试验装置的设计在任何时候都能达到真实的加载条件。研究明确考虑了工业实践中常用的各类脊柱支撑配置和直立框架支撑配置，并生成了全面的测试数据。实验结果表明，通过单侧脊柱支撑稳定的托盘货架框架在垂直载荷作用下表现出平移和扭转的综合摇摆运动，并通过整个框架的整体三维屈曲而失效。研究发现，货架与货架之间的连接影响了下走道脊柱支撑的效果，而整体货架框架的强度与主货架框架和脊柱支撑之间的稳定力传递机制密不可分。直立框架在跨通道方向上的横向剪切刚度在决定整体货架框架的抗扭性能和强度方面起着关键作用。本文提出了通过单侧脊柱支撑稳定托盘货架的设计建议。

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
