The book aims at explaining basic concepts in a simplified manner. For a successful structural design, one need to know physics of the problem what we mean by structural behavior. Then a formal mathematical process falls in a more conceptual manner rather than just computatiol procedures, as required by the new examition system. It is our objective to keep the presentation systematic, consistent, intensive and clear through explatory notes and figures. Main feature of this book is, complete coverage of New Credit System Syllabus with large number of solved examples and exercise. Model Question Papers for practice are included at the end of book
