This Specification and companion Commentary (hereinafter referred to as the Specification) applies to industrial pallet racks, movable shelf racks, rack supported systems and stacker racks made of cold-formed or hot-rolled steel structural members. Such rack types also include push back rack, pallet flow rack, case flow rack pick modules and rack supported platforms. This Specification is intended to be applied to the design of the storage rack portion of any rack structure that acts as support for the exterior walls and roof, except as noted. It does not apply to other types of racks, such as drive-in or drive-through racks, cantilever racks, portable racks, or to racks made of material other than steel.

ABSTRACT A study was undertaken to investigate the composite behavior of a Geosynthetic Reinforced Soil (GRS) mass. Many studies have been conducted on the behavior of GRS structures; however, the interactive behavior between the soil and geosynthetic reinforcement in a GRS mass has not been fully elucidated. Current design methods consider the reinforcement in a GRS structure as “tiebacks” and adopt a design concept the reinforcement strength, Tf, and reinforcement spacing, Sv, have the same effects on the performance of a GRS structure. This has encouraged the designers to use stronger reinforcement at larger spacing, as the use of larger spacing will generally reduce time and effort in construction. A series of large-size Generic Soil-Geosynthetic Composite (GSGC) tests were designed and conducted in the course of this study to examine the behavior of GRS mass under well-controlled conditions. The tests clearly demonstrated that reinforcement spacing has a much stronger effect on the performance of GRS mass than reinforcement strength. An analytical model was established to describe the relative contribution of reinforcement strength and reinforcement spacing. Based on the analytical model, equations for calculating the apparent cohesion of a GRS composite, the ultimate load carrying capacity of a reinforced.....

Dear Admin and all staff, welcome back with CivilEA. I was wondering what happened with the pints, I mean that at each thread or post or something else we were getting some points which were displayed bellow the thanks. There is available that option anymore or you lost that information or you have just modified this fact?
The proceedings consist of 28 high quality papers from geotechnical and structural engineers and researchers which have been individually refereed to check for relevance to the theme of the workshop as well as for quality of technical content and presentation. In addition, full accounts of the two discussion sessions are also included in this volume. The editors therefore hope that the papers presented in this workshop will further advance our understanding of soil-foundation-structure interaction.
The Soil-Foundation-Structure InteractionWorkshop (SFSI 09) held at the University of Auckland, New Zealand from 26–27 November 2009 brought together representatives from several of these groups to review the current state of development, discuss the potential for application in performance based design, and consider how work in this area might develop in the next few years. The emphasis in the workshop was on application of these ideas to the foundation design process.

Fatigue and wear are the most damaging phenomena affecting machines since they result in some 90% of breakdowns. This tutorial book systematically develops a unified overview, named tribo-fatigue, which aims to address the complex wear-fatigue damages. Tribo-fatigue synthesizes aspects of three disciplines: mechanical fatigue, tribology, and reliability of mechanical systems.
Tribo-fatigue opens new perspectives for increasing the durability of machines according to the most important criteria of their serviceability. Detailed damage measurement and wear-fatigue tests that enable engineers to design more durable and reliable systems are developed. The book is intended for advanced students, researchers and engineers.

SIGTTO (Society Of International Gas Tanker And Terminal Operators Ltd) (Author), OCIMF (Oil Companies International Marine Forum) (Author)
Jetty Maintenance and Inspection Guide:
This new book, which was jointly developed by SIGTTO and OCIMF, provides guidance on the effective maintenance of critical items of equipment on both oil and liquefied gas terminal jetties.
The book is structured in a consistent format, providing information on the basic function, failure, inspection, maintenance and repair of all of the key equipment items and systems. The publication reflects both proactive and reactive maintenance philosophies.
The Jetty Maintenance and Inspection Guide, which is 177 pages in length, is presented with colour diagrams and photographs to provide additional clarity to the text
The material in this work is focused on recent developments in research into the stress-strain behavior of geomaterials, with an emphasis on laboratory measurements, soil constitutive modeling and behavior of soil structures (such as reinforced soils, piles and slopes). The latest advancements in the field, such as the rate effect and dynamic behavior of both clay and sand, behavior of modified soils and soil mixtures, and soil liquefaction are addressed.
