WELDING AND METAL FABRICATION employs a unique hands-on, project-based learning strategy to teach welding skills effectively and keep you motivated. This groundbreaking new book connects each welding technique to a useful and creative take-home project, making exercises both practical and personal--and avoiding the tedium of traditional, repetitive welding practices. To further enhance the learning process, every welding project includes a set of prints with specifications, like those used in production fabrication shops. This full-featured approach to skill-building reflects the reality of professional welding, where following prints and instructions precisely and laying out, cutting out, and assembling weldment accurately are just as essential as high-quality welding. The included projects are small to conserve materials during the learning process, but detailed instructions and abundant photos and illustrations guide you through a wide range of fabrication skills. Key steps and techniques within the small projects are also linked to larger projects presented at the end of each chapter, enabling you to apply what you have learned by fabricating and welding something more substantial. This thorough, reader-friendly book also prepares you for real-world success by covering shop math and measurement, time and material tracking, and invoicing.

Now nearing its 30th year of publication, WELDING: PRINCIPLES & APPLICATIONS (WP&A), 7th Edition is the authoritative introduction to the subject of welding. It's designed for students in a wide range of academic and workforce training programs who want to pursue careers as skilled welders and welding supervisors. The text also supports the needs of learners who need to achieve a basic level of proficiency in welding in their chosen skilled trade. While covering the procedural and safety information all students need, WELDING: PRINCIPLES & APPLICATIONS also explains underlying theories. The combination of hands-on information with clear explanations of theory is a hallmark of this book. The depth of coverage allows it to be used as the core text in a multi-course welding curriculum, generally starting with shielded metal arc welding, and then covering other basic processes and more advanced techniques.

AIJ structural design guidelines for reinforced concrete buildings
Author: AIJ | Size: 32.8 MB | Format:PDF | Quality:Scanner | Publisher: architectural institute of japan | Year: 1994 | pages: 212 | ISBN: -
PREFACE TO THE ENGLISH TRANSLATION
This publication complies the English translation ofthe AU "Design Guidelines for Earthquake Resistant Reinforced Concrete Buildings Based on Ultimate Strength Concept" of the 1990 edition
and "Standard for Structural Calculation of Reinforced Concrete $truclUres" of the 1991 edition. In addition to the provisions of the Guidelines and Standard, a summary of commentaries on the Guidelines are translated. Parts of commentaries referring issues particular to Japanese practice and those of less significance for the interpretation of the Guidelines are omitted for a compact translation.
Figures, Tables, Equations and Reference Literatures in the translated edition carry numbers identical 10 those in the Japanese original. Figures. Tables and others in the English edition are not
arranged in complete sequential order, since some were omitted in translation. The draft of this English translation has been, in principle, prepared by those who were in charge of preparation ofthe Japanese original as listed in the separete sheet. The Standard, which first published in 1933 followed by several revisions, introduces a method of structural calculation based on allowable stress concept, and has been commonly utilized in structural design practice in Japan. The Guidelines proposed first in November, 1988 has been developed with an intention that it will be the so-called model code providing philosophies in structural design in addition to a design method, which describes exclusively a seismic design procedure for reinforced concrete buildings.
The originals of the Standard and Guidelines in Japanese are authentic.

fib Bulletin No. 57 - Shear and punching shear in RC and FRC elements
Author: This Bulletin N° 57 is a collection of individual contributions to a workshop. | Size: 80 MB | Format:PDF | Quality:Scanner | Publisher: International Federation for Structural Concrete (fib) | Year: 2010 | pages: 268 | ISBN: 978-2-88394-097-0
fib Bulletin 57 is a collection of contributions from a workshop on "Recent developments on shear and punching shear in RC and FRC elements", held in Salò, Italy, in October 2010. Shear is one of a few areas of research into fundamentals of the behaviour of concrete structures where contention remains amongst researchers. There is a continuing debate between researchers from a structures perspective and those from a materials or fracture mechanics perspective about the mechanisms that enable the force flow through a concrete member and across cracks.
In 2009, a Working Group was formed within fib Task Group 4.2 "Ultimate Limit State Models" to harmonise different ideas about design procedures for shear and punching. An important outcome of this work was the ensuing discussions between experts and practitioners regarding the shear and punching provisions of the draft fib Model Code, which led to the organization of the Salò workshop. Invited experts in the field of shear and FRC gave 18 lectures at the workshop that was attended by 72 participants from 12 countries in 3 different continents.
The contributions from this conference as compiled in this bulletin are believed to represent the best of the current state of knowledge. They certainly are of general interest to fib members and especially helpful in the finalization of the 2010 fib Model Code. It is hoped that this publication will stimulate further research in the field, to refine and harmonize the available analytical models and tools for shear and punching design.
