In the paper the author attempts to assess the fatigue life of chosen welded joints. It focuses especially on chosen problems that accompany determination of the fatigue life of welded joints, taking into consideration the strain energy density parameter. Chapter 2 describes the welded joint as a stress concentrator. The state of stress and strain in the notch are described and theoretical and fatigue coefficients are indicated. The fatigue coefficient of the notch effect is estimated on the basis of fictitious radius in the notch root. Chapter 3 presents a model of fatigue life assessment under uniaxial stress state with statistical handling of data presented. The new energy model of fatigue life assessment, which rests upon the analysis of stress and strain in the critical plane, is described in detail in chapter 4. The principle of such a description is presented in the uniaxial as well as in biaxial state of loading. Chapter 5 contains the analysis of tests of four materials subjected to different loadings: cyclic, variable-amplitude with Gaussian distribution, and variable amplitude with Gaussian distribution and overloading for symmetric and pulsating loading. The analysis is based on the determined fatigue characteristics for all the considered materials. Chapter 6 shows the application of the model in the fatigue life assessment in the complex state of loading (bending with torsion of flange-tube and tube-tube joints) based on fatigue research of steel and aluminum welded joints carried out in well-known German centres. Proportional and out-of-proportional cyclic research are carried out. Additionally, the influence of various bending and torsion frequencies and proportional and out-of-proportional variable amplitude loadings are analyzed.

Concrete in Coastal Structures
Edited by Richard T L Allen
ISBN: 9780727736376
Format: Paperbound
Publish Date: 09/04/1998
Publisher: Thomas Telford Ltd
Page Size: 276x219mm
Number of Pages: 312
Description
Many types of structure are subject to maritime conditions, and construction and maintenance of coastal structures is a major part of the construction workload of any country bordering the sea. This book is a comprehensive source of information for all who are concerned with the commissioning, design, construction or maintenance of concrete structures in or near the sea.
As well as describing the nature of the marine environment and the effects of man-made structures on the behaviour of the sea, this books deals with hydraulic design, the material properties of concrete and the design and specification of structures for coastal environments. The deterioration of concrete in coastal structures is usually a result of lack of durability rather than overloading, so much of the book has been directed towards the production of durable structures. British standards and other standards and codes from around the world are discussed, along with the planning of construction works under coastal conditions, and the maintenance of coastal structures.
All of the chapters were written specially for this book by practising engineers with specialised knowledge and wide experience of coastal engineering. As most of the authors have been responsible for work in many parts of the world, this book is relevant regardless of where coastal structures are situated.
Contents
The coastal environment and protection
Hydraulic calculation and armouring
Durability of concrete at the coast
Design guides and standards
Specifications Design of coastal structures
Movements and joints
Planning and construction

EN 771 Standard series Specification for masonry units
EN 771-1 Specification for masonry units - Part 1: Clay masonry units
This EN specifies the characteristics and performance requirements for masonry units manufactured from clay for use in masonry construction (e.g. facing and rendered masonry, loadbearing or non-loadbearing masonry structures, including internal linings and partitions, for building and civil engineering). This EN is intended to apply to all fired-clay masonry units used in masonry construction, including those of an overall non-rectangular parallelepiped shape.
EN 771-2+AC Specification for masonry units - Part 2: Calcium silicate masonry units
This EN specifies the characteristics and performance requirements of calcium silicate masonry units for which the main intended uses are inner walls, outer walls, cellars, foundations and chimneys, including those of an overall non-rectangular parallelepiped shape, specially shaped and accessory units.
