Toxicity of Building Materials
Author: Fernando Pacheco-Torgal, Said Jalali, Aleksandra Fucic | Size: 5 MB | Format:PDF | Quality:Unspecified | Publisher: Woodhead Publishing | Year: 2012 | pages: 512 | ISBN: 9780857091222
In the past, toxicity aspects have been a field outside the boundaries of the construction industry, with its practitioners belonging to the realm of health professionals. That is why architects, civil engineers and other professionals involved in the construction industry have so little knowledge about this area. Therefore, a new approach to building materials is needed-a more integrative one that is capable of joining the best efforts of construction practitioners and health specialists. Bringing together important contributions from several international experts from very different specialties, this book is intended to fill the gap by analyzing several aspects related to the toxicity of building materials.Beginning with an overview of the material types and potential health hazards presented by building materials, chapters consider key plastic materials, materials responsible for formaldehyde and semi-volatile organic compound emissions, wood preservatives and mineral fiber-based building materials. The contributors also discuss the use of radioactive materials, materials that release toxic fumes during burning, materials prone to mold growth and antimicrobials. The concluding chapter considers the potential hazards posed by waste-based/recycled building materials and the toxicity of nanoparticles.

The objective of this multi-disciplinary book is to provide a collection of expert writing on different aspects of pre- and post- tsunami developments and management techniques. It is intended to be distributed within the scientific community and among the decision makers for tsunami risk reduction.
It presents advanced methods for tsunami measurement using Ocean-bottom pressure sensor, kinematic GPS buoy, satellite altimetry, Paleotsunami, Ionospheric sounding, early warning system, and scenario based numerical modeling. Classifying tsunamis into local, regional and global, their possible impact on the region and its immediate vicinity is highlighted.
It also includes the effects of tsunami hazard on the coastal environment and infrastructure (structures, lifelines, water resources, bridges, dykes, etc.); and finally the need for emergency medical response preparedness and the prevention of psychological consequences of the affected survivors has been discussed.

I am current working on a Africa mining project. Anyone have the spreadsheet to calculate the building wind load and seismic load. The design code is SANS (south Africa code) which is base on Europe design code. Thanks you very much. I can use Canada same spreadsheet for exchange.
Intended as a main text which covers all years of an undergraduate course, this book has two aims: to cover the principles of mechanics and basic structural concepts; and to explain computer methods in structural analysis. In the new edition, the second chapter has been completely re-written to make it clearer and easier for first-year students, and there is increased coverage of plane statistics and introductory vector analysis. There is a greater design-based emphasis and more material on the principle of virtual work. Computer methods are referred to throughout and computer applications are included. New worked examples (with solutions) and new end-of-chapter problems are included, and references to the instability of linkages and the lateral buckling of beams have been added.

Despite being the most common construction practice throughout the ages, infills have not found the space it deserves, in the structural design. There is lack of proper and easy method to consider the effect of the in-filled. So, this research is a small effort in the search of the alternative approach for analyzing the infill frames. The FEM Models are normally incapable of considering all the effecting factors such as
non-linear behavior of the infill materials, lack of fit, non-homogeneity of the materials, etc. This research gives some idea to the structural engineer how to guess initially the parameters of interest during the design of infills. Structural design process is an iterative process and an approximate initial guess can reduce the time and cost involved in the analysis. The tentative design parameters can be predicted using the Artificial Intelligence and this computing power of the modern day computers has been used to fulfill the intended purpose. The data sets, which are generated by computer from the simulation of the infill-frame structure done in sophisticated software (ANSYS v10.0) capable of non-linear analysis, are used for the training of Neural Network. Few other unique data sets are taken for the validation of the Network trained. The comparison of the results from the ANN and that of software were in reasonable agreement with each other except in few rare cases.

This publication has been prepared with the aim of simplifying and standardising welding procedures used in structural steelwork, The need for such a document was first identified some years age by a group of welding engineers,steelworks contractors, metallurgists and industry experts and a draft document was produced outlining how this might be achieved and the range of variables which typically needed to be considered,

IIW Recommendations on Methods for Improving the Fatigue Strength of Welded Joints IIW-2142-110.
Author: P. J. Haagensen and S. J. MaddoxOxford | Size: 4 MB | Format:PDF | Quality:Unspecified | Publisher: Woodhead Pub Ltd | Year: 2013 | pages: 46 | ISBN: 9781782420644
The weld toe is a primary source of fatigue cracking because of the severity of the stress concentration it produces. Weld toe improvement can increase the fatigue strength of new structures significantly and can also be used to repair or upgrade existing structures. However, practitioners have reported wide variations in the actual improvements in fatigue strength. Based on an extensive testing program organized by the International Institute of Welding (IIW), this report reviews the main methods for weld toe improvement to increase fatigue strength: burr grinding, TIG dressing and hammer and needle peening. The report provides specifications for the practical use of each method, including equipment, weld preparation and operation. It also offers guidance on inspection, quality control and training as well as assessments of fatigue strength and thickness effects possible with each technique. These recommendations will allow for a more consistent use of these methods and more predictable increases in fatigue strength.

The notch stress approach for fatigue assessment of welded joints is based on the highest elastic stress at the weld toe or root. In order to avoid arbitrary or infinite stress results, a rounded shape with a reference radius instead of the actual sharp toe or root is usually assumed.Wolfgang Fricke reviews different proposals for reference radii together with associated S-N curves. The guidelines give detailed recommendations for the numerical analysis of notch stress by the finite or boundary element method and present appropriate S-N curves for the assessment of the fatigue strength of different materials. Finally, four examples illustrate the application of the approach as well as the variety of structures which can be analyzed and the range of results which can be obtained from different models. Published in Association with the International Institute of Welding (IIW).
