The purpose of this guide is to advise structural engineers, architects and fabricators of the properties and capabilities of iron, carbon steel and stainless steel castings. It emphasises that the high strength, ductility and toughness of these castings, coupled with their efficient production method, offer cost-effective solutions for a variety of structural components. Additionally, castings have excellent surface finish, together with good welding and machining characteristics. Functional shapes can be streamlined to give the best combination of strength, stiffness, slenderness and weight, thus saving on materials and minimising manufacturing costs. The guide explains the basic processes and techniques of casting and provides information for the designer on welding, surface finishes, tolerances and inspection and testing methods. The guide emphasises that the specification of the correct casting techniques and the appropriate level of quality are very important and require close liaison between the foundry and the design and construction teTahme .
procurement process is explained and illustrated with flowcharts. Appendices give exampleos f recent projects using structural castings, including four detailed case histories featuring main trussc onnections, glazing connections, beam to column connections and compression members in a bridge. Lists of sources of further information and the addresses of some UK foundries are also given.

A concrete filled structural hollow section provides architects and engineers with a robust and inherently fire resistance column. This publication contains design information for these columns for both the normal and fire conditions. The information is based on Eurocode 4. Also included are case studies illustrating the use of concrete filled columns and practical guidance on concrete filling and connection design. Design software, ConcFill 2, is described which will analyse sections for the normal and fire conditions.

This publication offers guidance to structural engineers considering, specifying and checking site welding. Its purpose is to create a better understanding and confidence in site welding, and to provide sufficient information to enable non-specialist structural engineers to manage site welding successfully.
Many features of site welding common to both shop and site welding are covered in sufficient detail to provide background to the site-specific guidance. Site practice for cutting and welding both new and existing material on site is described, together with
advice on the issues to be considered prior to specifying site welding. Although the structural engineer is unlikely to be directly responsible for certain activities, such as preparing welding procedure specifications, activities outside the structural designer’s
responsibility are described in order to cover the subject comprehensively.
This publication includes sections on: welding structural steel and other materials, site practices and procedures, designing for site welding, quality assurance and weld testing. The publication does not replace expert welding advice. Qualified welding engineers should be consulted for specific advice in situations outside the scope of this publication.

Chinese workers build 15-story hotel in just six days - ARK HOTEL
A construction crew in the south-central Chinese city of Changsha has completed a 15-story hotel in just six days. If nothing else, this remarkable achievement will stoke further complaints from American economic pundits that China's economy is far more accomplished than ours in tending to such basics as construction.
The work crew erected the hotel -- a soundproofed, thermal-insulated structure reportedly built to withstand a magnitude 9 earthquake -- with all prefabricated materials. In other words, a crew of off-site factory workers built the sections, and their on-site counterparts arranged them on the foundation for the Ark project. Despite the frenetic pace of construction, no workers were injured -- and thanks to the prefab nature of the process, the builders wasted very few construction materials.

This book has evolved from over 30 years of teaching advanced seniors and first-term graduate students a core course on the application of the full-range field theory of deformable solids for analysis and design. It is presented to help teachers meet the challenges of leading students in their exciting discovery of the unifying field theories of elasticity and plasticity in a new era of powerful machine computation for students with little experimental experience and no exposure to drawing and graphic analysis. The intention is to concentrate on fundamental concepts, basic applications, simple problems yet unsolved, inverse strategies for optimum design, unanswered questions, and unresolved paradoxes in the hope that the enthusiasm of the past can be recaptured and that our continued fascination with the subject is made contagious.

Precast Concrete: Materials, Manufacture, Properties and Usage

This book is intended to meet the need for a general treatise on precast concrete, as the last relevant book on this subject was published in 1961. Since then there have been several publications dealing with particular parts of the subject which serve as useful back-up reading, but the precast concrete industry is complex and needs to be discussed in both general and particular terms over a large number of subject areas.

BS ISO 10332:2010 Non-destructive testing of steel tubes — Automated ultrasonic testing of seamless and welded (except submerged arc-welded) steel tubes for verification of hydraulic leak-tightness
This International Standard specifies requirements for automated ultrasonic shear-wave (generated by single element probes or the phased-array technique) testing of seamless and welded (except submerged arcwelded) steel tubes, for verification of hydraulic leak-tightness.
The testing technique is applied for the detection of predominantly longitudinal imperfections. Where applicable, Lamb-wave testing may be applied at the discretion of the manufacturer. This International Standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 10 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5.

The processes and techniques referred to in this Part of EN 1011 may not all be relevant to all materials.
Additional information relevant to specific materials is given in the relevant Parts of the Standard.

Composite Slabs and Beams using Steel Decking
Best Practice for Design and Construction
This guide covers the design and construction of composite floors, paying particular attention to the good practice aspects. Following a description of the benefits of composite construction and its common applications, the roles and responsibilities of the parties involved in the design and construction process are identified. The requirements for the transfer of information throughout the design and construction process are described.
The design of composite slabs and beams is discussed in detail in relation to the Eurocodes and BS 5950. In addition to general ultimate and serviceability limit state design issues, practical design considerations such as the formation of holes in the slab, support details, fire protection, and attachments to the slab are discussed. Guidance is also given on the acoustic performance of typical composite slabs. The obligations of designers according to the CDM Regulations are identified and discussed. The practical application of Slimdek construction, which normally utilises deep decking and special support beams, is also covered. Typical construction details are illustrated, and guidance is given on the formation of openings in the beams and the slab.
Especially for Grunf
