There is no textbook published today which covers all of the needed items as we would like. Therefore, the topic material as presented in lecture constitutes the core of the course.  In addition the following textbook can be used for the course

Michael C. Y. Niu, Airframe Structural Design: Practical Design Information and Data on Aircraft Structures, Conmilit Press Ltd, 1999. 

Furthermore, these books serve as more permanent and referable material than class notes:

Denis Howe Aircraft Loading and Structural Layout, John Wiley & Sons, 2004.

Michael C. Y. Niu, Airframe Stress Analysis and Sizing, Conmilit Press Ltd, 2001. 

T.H.G. Megson, Aircraft structures for engineering students, Edward Arnold, 1990.

Perry D. J., Azar, J. J., Aircraft Structures, McGraw-Hill, 1982.

Bruhn, Analysis & Design of Flight Vehicle Structures, Jacobs & Associates, Inc. 1973.
