Manual for the Design of Steelwork Building Structures to Eurocode 3 October 2010
Published by: The Institution of Structural Engineers
First published: 2010
ISBN: 9781906335168
"This Manual is intended to provide guidance on the design of many common steel building frames and to show how the provisions of BS EN 1993-1-1: 2005, BS EN 1993-1-8: 2005 and BS EN 1993-1-10: 2005 can be selected for that purpose. Steel buildings frequently include composite floors and the Manual also covers some aspects of BS EN 1994-1-1: 2004. Certain limitations have been introduced to simplify the design process and to select from the comprehensive provisions of EC3 in order to aid the process of familiarisation. Much useful advice contained within the 2008 ‘grey’ book Manual for the design of steelwork building structures has been retained and will therefore be familiar to many users of this new Manual. Chapter headings appear similar to the old ‘grey’ book but opportunity has been taken to rationalise and reorder various sections"

EMERGING APPLICATIONS OF HIGH PERFORMANCE STEEL AND ULTRASOUND IMPACT TREATMENT FOR IMPROVED FATIGUE LIFE OF STEEL BRIDGES
Abstract ; Statnikov E. S.2; and Tehini L.3
With the advent of high performance materials, emerging advanced technologies and emphasis on the Federal Highway Administration’s (FHWA) Strategic Goals to mitigate congestion during construction as well as during the service life of a structure, the national perspective in the highway industry is changing towards rapid construction of highways and bridges; as well as to the deployment of maintenance techniques that can be performed quickly, economically, and effectively to achieve long lasting structures to safely transport people and goods.
This paper highlights recent advances in High Performance Steels (HPS) and maintenance technique employing Ultrasonic Impact Treatment (UIT) for steel bridges. These bridges will last longer, resist corrosion and fatigue cracking, and can be maintained efficiently and economically compared to those built and maintained in a traditional manner using conventional bridge steels. This material (steel) development effort has led to high strength 50-100 ksi (345 to 690 MPa yield strength), improved weldability, high toughness, and improved weathering (atmospheric corrosion resistant). Currently, high performance steel grades: HPS 50W, HPS 70W and HPS 100W are available. For the reasons explained above, this paper will address (a) Construction of New Structures Using High Performance Steels (HPS) and, (b) Maintenance of Structures Using Ultrasonic Impact Treatment (UIT).

This guide covers the stabilisation of naturally occurring soils or other materials to improve their mechanical properties and performance for use in capping layers, sub-bases and bases. This document, to be in line with European standards and Highways Agency documents, covers treatment with cement and the full range of hydraulic combinations based on fl y ash, granulated blastfurnace slag, gypsum and lime. The resulting materials are known as hydraulically-bound mixtures (HBM). After the introduction, which describes HBM and what they do, the guide describes the following aspects of HBM:
- binder selection
- soil/aggregate selection
- site investigation and preliminary assessment
- mixture design
- production and construction
- construction control.
Each part is designed to be stand-alone and self-contained. Thus for example, should the reader be familiar with the capabilities of the various hydraulic and pozzolanic materials, the fi rst part can be glossed over, or, if guidance is sought solely on construction, then reference need only be made to the fi fth and sixth parts. A construction summary is also included in chapter 6 where time does not permit digestion of the whole construction section. Intentionally, the guide does not cover thickness design and specifi cation, but should provide the background for the formulation of such application documents. Much of what follows is of direct relevance to the treatment of contaminated materials where a process called stabilisation and solidifi cation can be used to ‘immobilise’ contaminated materials as well as improving their engineering properties. Similarly, much is of direct relevance to pavement recycling work. However, these techniques are not the subject of this publication.

This part of ISO 1920 specifies procedures for testing fresh concrete. It specifies the following test methods:
determination of consistence (slump test, Vebe test, degree of compactability, flow-table test and for high-fluidity concrete, the slump-flow test), determination of fresh density and determination of air content by the pressure-gauge method and by the water-column method.

There is a fact that there are many threads in the problems section that are not yet solve even if it is weeks/months ago. Possible reasons are:
a) Difficulty of the problem
b) Participation of members in problems section are low.
c) The problem is not clearly stated and ignored by members.
d) Age of post are too old causing members not to see those post.
We must encourage our members to fill up those thread and put the unsolved problems in priority. I suggest that point system for problems secion should be different from normal threads, the older the post the higher point a member can received if solved. If this will be the point system, a certain post will not be solved only because of difficulty.
The main objective is not just to have higher points but to gain more confidence on members that their problems will be solved in this forum.
Please share for me the BS 5497-1 Guide for the determination of repeatability and reproducibility for a standard test method and ISO and ISO 4109, Fresh concrete — Determination of the consistency — Slump test
