Preface
Graduate Aptitude Test in 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.
