The Racking Performance of Light-Frame Shear Walls
… model was advanced to predict the racking resistance of conventional multi-panel shear walls using simple formulae. The deflections of engineered and conventional shear walls were predicted using the energy method combined with empirical formulae to account for load-deformation …

The design and analysis of static pallet racking systems.
The essential purpose of a pallet racking system is to support the largest load possible in relation to its self weight, while maintaining ready access to individual pallets and preventing damage to stored goods. This should be achieved within the constraints imposed by design and safety …

Economic Comparison of Solar Racking Options to Decarbonize Florida Power & Light’s System
… In this thesis, we compare different solar racking options to minimize total system cost. We focus this analysis on the flat, tracking, and fixed racking options. We then estimate the Threshold Cost Ratio between each option and Tracking Solar, which dominates utility-scale solar projects in …

Modeling of the fundamental mechanical interactions of unit load components during warehouse racking storage
The global supply chain has been built on the material handling capabilities provided by the use of pallets and corrugated boxes. Current pallet design methodologies frequently underestimate the load carrying capacity of pallets by assuming they will only carry uniformly distributed, flexible …

Behaviour of reinforced concrete frames with lightweight blockwork infill panels.
… tested under two types of loading: horizontal racking loading only and combined vertical loads on columns and racking loading. The complete load-deflection response is considered in detail including. initial elastic behaviour, influence of cracking and the formation of collapse mechanisms after …

Stability of Levees and Floodwalls Supported by Deep-Mixed Shear Walls: Five Case Studies in the New Orleans Area
… joints, complex failure mechanisms, such as racking due to slipping along vertical joints between adjacent installations in the shear walls, can occur. Ordinary limit equilibrium analyses only account for a composite shearing failure mode; whereas, numerical stress-strain analyses can account …

The Influence of Semi-Rigid Connections on the Behaviour of Beam and Column Structural System
A storage racking system consists of three main parts: beams, uprights and the beam end connectors which provide semi-rigid connections between the beams and the uprights. The connections in storage systems are often boltless tabs. These tabs are engaged into perforations in the cold-formed upright …

Scale Model Shake Table Testing of Underground Structures in Soft Clay
… and Phase II tests explored the horizontal racking distortion of a shallow rectangular tunnel cross-section subjected to strong transverse ground shaking. Phase I test results and comparison with SHAKE models indicate that the test container can sufficiently mimic 1D free-field conditions, …

Lateral Strength and Ductile Behavior of a Mortise-Tenon Connected Timber Frame
… traditional timber frames are capable of ductile racking while reliably complying with ASCE 7-10 building code drift speci! cations, implying an increase in the ASCE 7-10 ductility factor (R) for wood frames when used as lateral force resisting elements. A secondary goal was to promote traditional …

Technoeconomic analysis of perovskite photovoltaic manufacturing for powering telecommunications Towers
… components such as installation labor and racking. With the lightweight and flexible form factor of perovskite solar modules, new applications become possible. One such application is the installation of perovskite photovoltaics (PV) vertically on telecommunications towers. Since such …

La influencia de la tecnología de la vinificación en la microbiología y el desarrollo de la fermentación alcohólica
… Aeration (by oxygen addition direct and racking), Survival factors addition (Ergosterol), Yeast hulls addition and inert cellulose substrates addition (tree celluloses with different physical characteristics). The more relevant results showed the influence of the type of grape juice …

Does Experiential Learning Add Value in Financial Literacy Education: A Qualitative Investigation
… $200 billion over the last twenty years. Besides racking up student loan debt that averaged about $37,172 per student in 2016 (Marketwatch.com) millennials and those in Generation Z are also the most likely to engage in risky financial behaviors like payday loans, pawnshops and tax refund advances …

Monotonic and Cyclic Performance of Structurally Insulated Panel Shear Walls
… In the past, research has focused on the static racking performance of light-framed shear walls. More recently, research has been focused on the cyclic and dynamic performance of shear walls. To the author's knowledge, no other research is reported in the literature on the cyclic performance of …

Investigation of the Effect of Corrugated Boxes on the Distribution of Compression Stresses on the Top Surface of Wooden Pallets
… This effect was only significant for warehouse racking across the width and length support conditions. As much as a 53% reduction in pallet deflection was observed for high stiffness pallets supporting corrugated boxes with 25.4 mm headspace when the size was increased from small to large. …

Investigation and Analysis of the Effect of Industrial Drums and Plastic Pails on Wooden Pallets throughout the Supply Chain
… support conditions commonly found in warehouses: racking across the width and length, single stacking, and double stacking. The results of the investigation indicated that for most support conditions, loading the pallet with plastic pails or drums results in a significant reduction in deflection …

Slamming of High-Speed Craft: A Machine Learning and Parametric Study of Slamming Events
… and center of gravity. This moment caused racking in the setup which was observed in the acceleration time histories immediately after impact. This finding furthers the need to investigate the angular velocity and acceleration of the model at impact, through the proposed series of …

Examination of the Lateral Resistance of Cross-Laminated Timber in Panel-Panel Connections
… CLT as an element to resist lateral forces from racking has been of great interest (Dujic et al. 2004, Blass and Fellmoser 2004, and Moosbrugger et al. 2006). However, most research to date has been conducted on full-scale wall panels connected with proprietary fasteners according to European …

Monotonic and Cyclic Performance of Light-Frame Shear Walls with Various Sheathing Materials
The racking performance of light-frame shear walls subjected to monotonic and cyclic loading is the focus of this thesis. The sheathing materials investigated are oriented strandboard (OSB), hardboard, fiberboard, and gypsum wallboard. The objectives of this study were to (1) obtain and compare …

The development of pre-service teachers' pedagogical content knowledge in electromagnetism
… knowledge (CK) and a CoRe tool for PCK. By racking the data in Rasch analysis, the perceived difficulty of items in the CK-tests and CoRe tool could be established and this enabled the researcher to report on specific areas of difficulty in electromagnetism that students encountered both in …
