This book provides students with a clear and thorough presentation of the theory and application of structural analysis as it applies to trusses, beams, and frames. Emphases are placed on teaching students to both model and analyze a structure. Procedures for Analysis, Hibbeler's problem solving methodologies provide student with a logical, orderly method to follow when applying theory.

 The text is divided into three parts.

 Part I - Classical methods of analysis for statically determinate structures (Chapters 1-7).
 Part II ? Analysis of statically indeterminate structures (Chapters 8-13).
 Part III ? Treats the Analysis of structures using the stiffness method (Chapters 13-16).

Problem Solving
 -Video Solutions ? Developed by Professor Jim Hanson, Rose-Hulman Institute of Technology, these are complete, step-by-step solution walkthroughs of representative homework problems from each chapter. Videos offer:
 -Fully-worked Solutions ? Showing every step of representative homework problems, to help students make vital connections between concepts.
-Self-paced Instruction ? Students can navigate each problem and select, play, rewind, fast-forward, stop, and jump-to-sections within each problem’s solution.
 -24/7 Access ? Help whenever students need it with hours of helpful review.
 -End-of-Chapter Review ? A new, thorough end of chapter review has been developed for the 7/e. Each important point is now accompanied by the relevant equation and art from the chapter providing the students a concise tool for reviewing chapter contents.
 -Problems ? Problems depict realistic situations encountered in practice. Throughout the book there is an appropriate balance of problems using either SI or FPS units. The intent has been to develop problems that test the student’s ability to apply the theory.
 -Procedure for Analysis ? Provides the student with a summary of the important concepts and a systematic approach for applying theory.
 -Answers to Selected Problems ? Provided in the back of the book.
 -STRAN computer program ? With the increased emphasis on using computers to analyze structures, STRAN provides students with a means of checking their worked out solutions.
 -Project Problems ? Problems that involve real structural systems are included at the end of selected chapters. They provide the student with insight as to how loads are determined and transmitted through the structure, as well as how the structure is designed to support the loadings.
 -Hibbeler's hallmark triple-accuracy checking

 Visualization
 -Illustrations ? Throughout the book, two-color art, including many photorealistic illustrations provides students with a visual connection to the 3-D nature of engineering.
 -Photographs ? Used throughout the book to explain how the principles of structural analysis apply to real-world situations.
