Preface to Matrix Methods of Structural Analysis

Matrix methods of structural analysis are used for the analysis of the framed structures, i.e., structures composed of one-dimensional elements.

The solution procedures used in this method are systematic and general. Hence, it is easier to write computer programs using this method. The matrix method of analysis is an important topic in the field of structural engineering.

A piece of proper knowledge in this area is necessary to understand advance topics like finite element method, structural dynamics, structural stability, etc. The software available for the analysis of structures is developed using this method.

Hence, it is necessary to have a background in this subject for the proper application of these software tools. This book deals with the analysis of structures using matrix methods.

It is designed as an easy-to-read textbook for an introductory course in matrix methods of structural analysis for senior undergraduate and postgraduate students of civil engineering.

It will be also useful for practicing structural engineers for the efficient usage of structural analysis software tools. The key features of the book are as follows: 

  • The concepts are explained in a simple manner. 
  • Each chapter contains plenty of illustrations and examples for improved understanding. 
  • A step-by-step approach for problem-solving is adopted in the book which will help the reader to solve problems in a systematic way.

The book contains five chapters. In the first chapter, the background to matrix analysis of structures is discussed.

The procedure to develop force-displacement relation for a given structure using flexibility and stiffness coefficients is covered in the second chapter. The remaining three chapters deal with the analysis of framed structures using the flexibility, stiffness, and direct stiffness method.

A simple MATLAB code for analyzing plane truss using the direct stiffness method is given in the appendix of the book. The code can be modified so that it can be used for the analysis of other types of structures.

The author sincerely thanks Dr. Gagandeep Singh, Ms. Mouli Sharma and Mr. Edward Curtis of CRC Press and Ms. Alexandra Andrejevich of codeMantra for all the support and to Mr. Beljith P., for typing the manuscript.

The author welcomes comments, feedback, and suggestions for the improvement in the future edition of the book.
