Matrix Methods of Structural Analysis

This book describes in detail the matrix methods of structural analysis used for the analysis of skeletal or framed structures. The book provides comprehensive coverage of the subject, starting with the basics. It is organised in four parts. Part 1 contains the basic knowledge required to understand the subject: matrix operations, methods for solving equations, and concepts of flexibility matrix and stiffness matrix methods. Part 2 deals with the applications of stiffness and flexibility matrix methods using a system approach. By using simple examples, the steps involved in both the methods are discussed' this section concludes with discussion of why the stiffness matrix method is more suitable for analysis of skeletal structures. Part 3 covers the stiffness matrix (displacement) method with member approach (direct stiffness method) which is extensively used in the analysis of framed structures. It provides the details of the method, the steps involved in the method, and its application to plane truss, space truss, beams, plane and space frames, and grids. Part 4 includes a unified computer programme written in FORTRAN/C for the analysis of a framed structure. The development of computer programme, explanation of various subroutines, and input output formats with examples are also provided. An accompanying CD contains source code, explanation of INPUT/OUTPUT and test examples. The primary objective of the book is to present the subject matter in a simple manner so that it can serve as a basic learning tool for undergraduate and postgraduate students of civil engineering.
