EN ISO 14122 - Permanent means of acces to machinery
Analysis
This document forms part of a series of four type B2 European standards (safety standards relating to a group and dealing with safety devices) dealing with permanent means of access to machines. This document aims, as a priority, at designers so that they can choose the most appropriate means of access for their machines or installations. Once this choice is made, it will be possible to imagine means of access which meet the corresponding essential requirements of the Directive "Machinery" 98/37/CE and its amendment 98/79/CE, which are explainedin the following parts:
— Part 2: Work platforms and footbridges (E 85-002).
— Part 3: Stairway, stepladder and guard rail (E 85-003).
— Part 4: Fixed ladder (E 85-004).
The range of application of this standard NF EN ISO 14122-1 extends to industrial buildings and installations (see national foreword and normative national Annex NA).
Descriptors
Technical International Thesaurus: industrial facilities, buildings, machinery, access facilities, stairs, ladders, categories, safety of machines, work safety, safety requirements, accident prevention, protection against fall, parapets, banisters.

Advanced Reinforced Concrete Design Book Description (scanned)
Intended as a companion volume to the author's Limit State Design of Reinforced Concrete (published by Prentice-Hall of India), the Second Edition of this comprehensive and systematically organized text builds on the strength of the first edition, continuing to provide a clear and masterly exposition of the fundamentals of the theory of concrete design. The text meets the twin objective of catering to the needs of the postgraduate students of Civil Engineering and the needs of the practising civil engineers as it focuses also on the practices followed by the industry.
This text, along with Limit State Design, covers the entire design practice of revised Code IS456 (2000). In addition, it analyzes the procedures specified in many other BIS codes such as those on winds, earthquakes, and ductile detailing.

This publication was commissioned by the Reinforced Concrete Council, which was set up to promote better knowledge and understanding of reinforced concrete design and building technology. The Council’s members are Co-Steel Sheerness plc and Allied Steel & Wire, representing the major suppliers of reinforcing steel in the UK, and the British Cement Association, representing the major manufacturers of Portland cement in the UK. Charles Goodchild is Senior Engineer for the Reinforced Concrete Council. He was responsible for the concept and management of this publication.
The ideas and illustrations come from many sources. The help and guidance received from many individuals are gratefully acknowledged on the inside back cover.
The charts and data in this publication were prepared to BS 8110, Pt 1: 1985, up to and including Amendment No 4. During production, BS 8110 Structural use of concrete: Part 1:1997 Code of practice for design and construction was issued. This incorporated all published amendments to the 1985 version plus Draft Amendments Nos. 5 and 6. In general, the nett effect of the changes is that slightly less reinforcement is required: preliminary studies suggest 2 to 3% less in in-situ slabs and beams and as much as 10% less in columns. Readers should be aware that some of the tables in the new Code have been renumbered. The charts and data given in this publication remain perfectly valid for pre-scheme design.

Assessing Soil and Groundwater Impacts of Chemical Mixture Releases from Hazardous Materials Transportation Incidents
Author: Richard G. Lewis Ziqi He | Size: 55.7 MB | Format:PDF | Publisher: Hazardous Materials Cooperative Research Program (HMCRP) Reports | Year: September 2010 | pages: 462 | ISBN: 978-0-309-15527-4
This report documents and presents the results of developing a Chemical Mixture Tool (CMT) for the study of Assessing Soil and Groundwater Impacts of Chemical Mixture Releases from
Hazardous Materials Transportation Incidents sponsored by the Transportation Research Board (TRB) of the US National Academies. The study was developed by HSA Engineers & Scientists
(HSA) (a member of the Conestoga Rovers & Associates (CRA) family of companies). It is a preliminary tool intended to estimate, assess, classify, predict, and quickly communicate the
various fate and transport characteristics of chemical mixtures released into the subsurface as a result of hazardous materials transportation incidents. The tool is intended to enable carriers, shippers, responders, risk compliance specialists, and regulators to predict and assess the potential environmental concerns, risks, and hazards to soil and groundwater posed by chemical
mixtures.

This report discusses the findings of a research project undertaken to investigate bridge scour in cohesive soils. The report presents a recommended method for predicting the extent of complex pier and contraction scour in cohesive soils. This report will be of immediate interest to engineers with responsibility for predicting the extent of scour at bridge foundations and to engineers with responsibility for designing bridge foundations and bridge scour countermeasures.

Author: Robert J.Connor, Michael J.Urban, Eric J.Kaufmann | Size: 10.75 MB | Format:PDF | Publisher: NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM | Year: 2008 | pages: 140 | ISBN: 9780309099370
This report summarizes the results of a project to establish limits, based on fatigue and fracture performance, on the number of damage and repair cycles to which damaged steel bridge girders may be subjected using the heat-straightening procedure. A key product presented here is suggested revisions to the Federal Highway Administration (FHWA) manual of practice for heat straightening. The report will be of particular interest to engineers in state highway agencies and industry responsible for bridge maintenance and repair.
