An Introduction

Automated Structural Analysis: An Introduction is a ten-chapter book that first discusses the ideas or laws fundamental to structures. Subsequent chapters describe the node method; node method for trusses, plane frames, and space frames; and the primitive stiffness matrix. The mesh method and Kron’s methods are also reported. This book will be useful for undergraduates involved in structural analysis.
