This book focuses on the plastic property of materials, and the way in which structures made of such material behave under load. It is intended for civil, mechanical, electro-mechanical, marine, and aeronautical engineers for under-graduate or post-graduate courses or research, and professionals in industry. Professor Calladine, from long experience in teaching, research and industry, here delivers a readable and authoritative account of theory and applications. He presents the classical "perfect plasticity material" as a model of irreversible mechanical behavior, using this perfect plasticity property to analyze a range of continuum structural problems and metal-forming processes relevant to engineering practice.

Earthquakes remain one of the major risks to buildings, bridges and other components of civil infrastructure. The editors and contributors summarize the wealth of recent research in this important book. The first two parts review research in the analysis of ground motion and seismic hazard assessment and discuss different seismic risk hazard methodologies.
Parts three and four cover the assessment of seismic risks to buildings, bridges, water supply systems and other aspects of civil infrastructure and the conclusion considers ways of assessing financial and other losses from earthquake damage.

The book approaches the basic theory of structures from a different perspective from standard pedagogy. There is consideration of work and energy concepts as fundamental and the equations of statics derived from them. Likewise, these concepts, together with that of the characteristic response, are used in the derivation of beam theory. Plane sections remaining plane is then seen as a particular result for isotropic, homogeneous, prismatic beams. The general theory may still be used where none of these conditions holds, and can even be applied to trusses. It also corrects errors in the theory of beam shear. Special topics discussed include non-uniform torsion, the exact analysis of shear, anisotropy, advanced energy methods, optimum structures, and regular frames. Software provided in the book includes seven general purpose programs for analysis of plane, space frames with rigid or pinned joints, and uses the augmented Gaussian elimination process and dynamic storage techniques.

This book was written to provide a quick guide to welding inspection that is easy to read and understand. It is difficult to find books specifically covering weld inspection requirements. This book will give you a basic understanding of the subject and so help you decide if you need to look further. In many cases the depth of knowledge required for any particular welding-related subject will be dependent on specific industry requirements. In all situations, however, the welding inspector s role is to ensure that welds have been produced and tested in accordance with the correct code specified procedures and that they are code compliant. Code compliance in this sense means that the weld meets all the requirements of the defect acceptance criteria specified within the code.

"What's the Crack?"
When cracking is observed in a building the most common reaction is that it must be the foundations and that it must be serious.
Many surveyors are nervous about diagnosing cracks. This is understandable, as the interpretation of cracks can be difficult to teach, with university courses providing little or no time for field experience. Yet by understanding one straightforward principle the majority of cracks can be diagnosed in just a few minutes. Linking this with a good knowledge of construction techniques, the factors that distort cracking patterns and the key features of common causes of cracking, almost all cracks can be diagnosed quickly and with confidence.
Practical Guide to Diagnosing Structural Movement in Buildings provides a methodology by which cracks and movement in buildings can be diagnosed. Written in four parts, part one describes the key principles of movement and cracking. Parts two and three describe the main features of common forms of movement and the associated crack patterns. Part two covers causes other than ground or foundation movement and part three covers movement caused by ground or foundation problems. Part four briefly describes the techniques used to arrest further movement or repair damage cause by movement.
Primarily intended for the relatively inexperienced surveyor or engineer and undergraduate students of surveying as a practical guide for use on site, it focuses on identification and diagnosis. It will not only help in correctly diagnosing the problem but it will also demonstrate a methodical approach to show and record how the diagnosis was reached – critical when giving advice to third parties.
"What's the crack?" - In the vast majority of cases it's not foundation related and in most cases it's not indicating a serious defect.

Above is the problem, but below is the software (a kind of solution)
Why users need this DWG secure software:
Keep others from copying and using part of your drawing
Protect the copyright of the design, especial useful for contractors
Collaboration needs, there is no more concerns of the reviewed drawings has been changed unexpected, while the mark up is still clear and easy to be enclosed.

Assessment of the Environmental Effects on the Performance of FRP Repaired Steel Pipes Subjected to Internal Pressure
Author: Ramadan A. Esmaeel, Mohamed A. Khan and Farid Taheri | Size: 1 MB | Format:PDF | Quality:Unspecified | Publisher: ASME | Year: 2011 | pages: 7
The use of composite materials for repair and rehabilitation of corroded steel pipes has
been increasingly growing in the oil and gas industry. However, there exists a noticeable
gap in the literature on the long term performance of composite repaired pipes, especially
those subjected to large internal pressure magnitudes. This work is an attempt toward
filing the gap by gaining a better understanding of the effects of environmental
conditions on the long term performance of composite repaired pipes subjected to large
internal pressures. Finite element method (FEM) is used to simulate typical composite
warp-repaired gouged steel pipes, conditioned in various environments and subsequently
subjected to internal pressure. The influence of the resulting degradation in composite’s
mechanical properties on the performance of the system was evaluated. To validate the
results, an experimental program was designed and carried out. Repaired specimens
were conditioned in an environmental chamber under certain thermal and moisture conditions;
then, the specimens were tested to failure subject to internal pressure. Good correlation
was obtained after fine tuning of FEM model’s material data through the use of
the experimentally obtained data.
