Engineering (GATE) is one of the preliminary tests for undergraduate subjects in Engineering/ Technology/Architecture and postgraduate subjects in Science stream only. The number of aspirants appearing for the GATE examination is increasing significantly every year, owing to multifac- eted opportunities open to any good performer. Apart from giving the aspirant a chance to pursue an M.Tech. from insti- tutions like the IITs /NITs, a good GATE score can be highly instrumental in landing the candidate a plush public sector job, as many PSUs are recruiting graduate engineers on the basis of their performance in GATE. The GATE examination pattern has undergone several changes over the years—sometimes apparent and sometimes subtle. It is bound to continue to do so with changing technological environment. GATE Civil Engineering, as a complete resource helps the aspirants be ready with conceptual understanding, and enables them to apply these concepts in various applications, rather than just proficiency with question types. Topics are handled in a comprehensive manner, beginning with the basics and progressing in a step-by-step manner along with a bottom-up approach. This allows the student to better understand the concept and to practice applicative techniques in a focused manner. The content has been systematically organized to facilitate easy understanding of all topics. The given examples will not only help the students to understand the concepts involved in the problems but also help to get a good idea about the different models of problems on a particular topic. Due care has also been taken to cover a very wide range of problems including questions that have been appearing over the last few years in GATE examination. The practice exercises in every chapter, contain questions ranging from simple to moderate to difficult level. These exer- cises are meant to hone the examination readiness over a period of time. At the end of each unit, practice tests have been placed. These tests will help the student assess their level of learning on a regular interval. This book has been prepared by a group of faculty who are highly experienced in training GATE candidates and are also subject matter experts. As a result, this book would serve as an effective tool for GATE aspirant to crack the examination. Salient Features of Revised Edition 1. Elaborate question bank covering previous 10 years’ GATE question papers 2. 3 free online mock tests for practice 3. Detailed coverage of key topics 4. Complete set of solved 2017 GATE online papers with chapter-wise analysis 5. Exhaustive pedagogy: (a) More than 1700 Solved Examples (b) More than 3500 Practice Questions (c) Unit-wise time-bound tests (d) Modular approach for easy understanding We would like to thank the below-mentioned reviewers for their valuable feedback and suggestions which has helped in shaping this book.
