CHAPTER 1:
1.1 Introduction
Drawing Instruments and
Accessories
Engineering drawing is a two dimensional representation of three dimensional objects. In general, it provides necessary information about the shape, size, surface quality, material, manufacturing process, etc., of the object. It is the graphic language from which a trained person can visualise objects. Drawings prepared in one country may be utilised in any other country irrespective of the language spoken. Hence, engineering drawing is called the universal language of engineers. Any language to be communicative, should follow certain rules so that it conveys the same meaning to every one. Similarly, drawing practice must follow certain rules, if it is to serve as a means of communication. For this purpose, Bureau of Indian Standards (BIS) adapted the International Standards on code of practice for drawing. The other foreign standards are: DIN of Germany, BS of Britain and ANSI of America.
1.2 Role of Engineering Drawing
The ability to read drawing is the most important requirement of all technical people in any profession. As compared to verbal or written description, this method is brief and more clear. Some of the applications are : building drawing for civil engineers, machine drawing for mechanical engineers, circuit diagrams for electrical and electronics engineers, computer graphics for one and all. The subject in general is designed to impart the following skills.
1. Ability to read and prepare engineering drawings.
2. Ability to make free - hand sketching of objects.
3. Power to imagine, analyse and communicate, and
4. Capacity to understand other subjects:
1.3 Drawing Instrument and Aids
The Instruments and other aids used in draughting work are listed below:
1. Drawing board 2. Mini draughter 3. Instrument box
4. Set squares 5. Protractor 6. Set of scales
7. French curves 8. Drawing sheets 9. Pencils

Modeling Soil Liquefaction Hazards for Performance-Based Earthquake Engineering
by Kramer & Elgamal
The first widespread observations of damage attributed to liquefaction were made in the 1964 Niigata, Japan, and 1964 Alaska earthquakes. In numerous earthquakes since, liquefaction has been deemed responsible for significant damage to buildings and bridges. Liquefaction has been studied extensively over the past 35 years, and substantial advances have been made in understanding the development and effects of this phenomenon. These advances have led to a series of practical procedures for evaluating the potential for occurrence and for estimating its effects. These procedures, however, are almost entirely empirical in nature and, as such, are difficult to apply to the problem of performance prediction for individual structures. The Pacific Earthquake Engineering Research (PEER) Center is committed to the development of methods and procedures for performance-based earthquake engineering (PBEE). The use of PBEE requires the ability to predict a nearly continuous spectrum of performance states for individual structures. This requirement implies the need for tools and procedures for evaluation of the entire process of liquefaction — from initiation to effects. Recent advances in the understanding of liquefaction-related phenomena offer the promise of improved analytical predictions of the initiation and effects of soil liquefaction. The purpose of this synthesis report is to summarize current procedures for practical prediction of liquefaction behavior, to describe recent advances in the understanding of liquefaction behavior, and to describe the incorporation
of this improved understanding into new solutions for detailed modeling of soil liquefaction. The focus of this report, however, is on performance, and the reader should expect that aspects of liquefaction that relate to the performance of buildings, bridges, and lifelines will be emphasized. Well-known and widely used empirical tools and procedures for evaluation of liquefaction hazards will be reviewed relatively briefly, with more detailed discussions devoted to emerging knowledge about the mechanics of liquefiable soil behavior, and methods for incorporating those mechanics into improved models for performance prediction.

Modelling Soil-Structure Interaction, Kolar and Nemec
# Hardcover: 333 pages
# Publisher: Elsevier Publishing Company (March 1990)
# Language: English
# ISBN-10: 0444988599
# ISBN-13: 978-0444988591
Product Description
Distributed in the East European countries, China, Northern Korea, Cuba, Vietnam and Mongolia by Academia, Prague, Czechoslovakia This book is based on the efficient subsoil model introduced by the authors in 1977 and applied in the last ten years in the design of foundations. From the designer's point of view, the model considerably reduces the extent of the calculations connected with the numerical analysis of soil-structure interaction. The algorithms presented are geared for use on mini- and personal computers and can be used in any numerical method. A special chapter is devoted to the implementation of the model in the NE-XX finite element program package, illustrated with diagrams, tables and practical examples. Besides presenting the energy definition and general theory of both 2D and 3D model forms, the book also deals with practical problems such as Kirchhoff's and Mindlin's foundation plates, interaction between neighbouring structures, actual values of physical constants of subsoils and natural frequencies and shapes of foundation plates. Today, researchers and engineers can choose from a wide range of soil models, some fairly simple and others very elaborate.

Underpinning and Retention
Editors: S. Thorburn , G.S. Littlejohn
Hardcover: 416 pages
Publisher: Taylor & Francis; 2nd Ed edition (12 Nov 1992)
Language: English
ISBN-10: 0751400947
ISBN-13: 978-0751400946
Various underpinning methods exist, and choosing a particular method or selection of methods is the job of the engineer. Consistent with the underpinning procedure is the need to retain the affected structure plus the surrounding ground and/or buildings. This book will offer advice on how to chose the correct procedure.

COMMENTARY ON THE GUIDE FOR BUCKLING AND ULTIMATE STRENGTH ASSESSMENT FOR OFFSHORE STRUCTURES
This Commentary provides the fundamental principles and technical background, including sources and additional details, for the ABS Guide for Buckling and Ultimate Strength Assessment for Offshore Structures, April 2004, which is referred to herein as “the ABS Buckling Guide”. The Commentary presents supplementary information to better explain the basis and intent of the criteria that are used in the ABS Buckling Guide. The accuracy for determining buckling and the ultimate strength predictions obtained from the application of the ABS Buckling Guide is established by the comparison of its results against a very extensive database of test results assembled by ABS and also from the results of nonlinear finite element analysis. Results obtained using the criteria in the ABS Buckling Guide are also compared against existing recognized offshore standards, such as the ABS MODU Rules, API RP 2A WSD, API Bulletins 2U and 2V, DnV CN30.1, and AISC LRFD [references 1, 3, 5, 6, 7, 30].
