Chapters 1 through 3should be assigned, but the detailed information on loading in Chapter 2 can be covered in a second course. The information on concrete material properties in Chapter 3 could be covered with more depth in a separate undergraduate course. Chapters 4 and 5are extremely important for all students and should form the foundation of the first undergraduate course. 

The information in Chapter 4 on moment vs. curvature behavior of beam sections is important for all designers, but this topic could be significantly expanded in a graduate course. 

Chapter 5 presents a variety of design procedures for developing efficient flexural designs of either singly-reinforced or doubly-reinforced sections. The discussion of structural analysis for continuous floor systems in Section 5-2 could be skipped if either time is limited or students are not yet prepared to handle this topic.

 The first undergraduate course should cover Chapter 6information on member behavior in shear and the shear design requirements given in the ACI Code. Discussions of other methods for determining the shear strength of concrete members can be saved for a second design course. 

Design for torsion, as covered in Chapter 7, could be covered in a first design course, but more often is left for a second design course. The reinforcement anchorage provisions of Chapter 8are important material for the first undergraduate design course. Students should develop a basic understanding of development length requirements for straight and hooked bars, as well as the procedure to determine bar cutoff points and the details required at those cutoff points.

 The serviceability requirements in Chapter 9for control of deflections and cracking are also important topics for the first undergraduate course. In particular, the ability to do an elastic section analysis and find moments of inertia for cracked and uncracked sections is an important skill for designers of concrete structures. 

Chapter 10 serves to tie together all of the requirements for continuous floor systems introduced in Chapters 5 through 9. The examples include details for flexural and shear design, as well as full-span detailing of longitudinal and transverse reinforcement. This chapter could either be skipped for the first undergraduate course or be used as a source for a more extensive class design project.

Chapter 11concentrates on the analysis and design of columns sections and should be included in the first undergraduate course. The portion of Chapter 11 that covers column sections subjected to biaxial bending may either be included in a first undergraduate course or be saved for a graduate course. Chapter 12 considers slenderness effects in columns, and the more detailed analysis required for this topic is commonly presented in a graduate course. If time permits, the basic information in Chapter 15on the design of typical concrete footings may be included in a first undergraduate course. 

This material may also be covered in a foundation design course taught at either the undergraduate or graduate level.

Clearly, the instructor in a graduate design course has many options for topics, depending on his/her interests and the preparation of the students. Chapter 13is a lengthy chapter and is clearly intended to be a significant part of a graduate course. 

The chapter gives extensive coverage of flexural analysis and design of two-way floor systems that builds on the analysis and design of one-way floor systems covered in Chapter 5. The direct design method and the classic equivalent frame method are discussed, along with more modern analysis and modeling techniques. Problems related to punching shear and the combined transfer of shear and moment at slab-to-column connections are covered in presented. Finally, procedures for calculating deflections in two-way floor systems are given.

 Design for torsion, as given in Chapter 7, should be covered in conjunction with the design and analysis of two-way floor systems in Chapter 13. The design procedure for compatibility torsion at the edges of a floor system has a direct impact on the design of adjacent floor members. The presentation of the yield-line method in Chapter 14 gives students an alternative analysis and design method for two-way slab systems. This topic could also tie in with plastic analysis methods taught in graduate level analysis courses. The analysis and design of slender columns, as presented in Chapter 12, should also be part of a graduate design course

The students should be prepared to apply the frame analysis and member modeling techniques required to either directly determine secondary moments or calculate the required moment-magnification factors. Also, if the topic of biaxial bending in Chapter 11 was not covered in the first design course, it could be included at this point. Chapter 18covers bending and shear design of structural walls that resist lateral loads due to either wind or seismic effects.

 A capacity-design approach is introduced for the shear design of walls that resist earthquake-induced lateral forces. Chapter 17covers the concept of disturbedregions (D-regions) and the use of the strutand-tie models to analyze the flow of forces through D-regions and to select appropriate reinforcement details. The chapter contains detailed examples to help students learn the concepts and code requirements for strut-and-tie models. If time permits, instructors could cover the design of combined footings in Chapter 15, shear-friction design concepts in Chapter 16, and design to resist earthquake-induced forces in Chapter 20.
