Night School 20
Classical Methods of Structural Analysis
This course will address many of the classical methods used in the analysis of structures before the advent of the computer. It will illustrate how use of those methods can aid the engineer in understanding the modern analysis and design requirements for structural steel found in the AISC Specification, AISC 360-16. The course will start with a brief discussion of the history of structural analysis in order to place into context the development of these methods and to illustrate how they have influenced approaches currently used. The portal and cantilever methods, influence lines, slope-deflection method, and more will be reviewed. The method of moment distribution will be introduced and its link to the approximate second-order analysis approach of AISC 360-16 Appendix 8 will be discussed. The course will then discuss the “modern methods” of analysis and illustrate how they may be understood and developed from the classical methods already discussed.
We've prepared a few problems to whet your appetite for this upcoming Night School. Have some fun and solve these refresher problems to prepare for course topics such as virtual work, slope deflection, moment distribution and more. And if you don't get a perfect score, this course is perfect for refreshing your knowledge on these fundamental methods. Solutions will be posted by May 24, 2019.
Practice problems can be found here.

The session will start with a brief discussion of the history of structural analysis in order to place into context the development of classical methods of analysis and to illustrate how they have influenced approaches currently used. Such topics as equilibrium, superposition, first- and second-order analysis, determinate and indeterminate structures, shear and moment diagrams, and deflected shapes will be reviewed. AISC specification requirements will also be discussed.
This lesson will begin with developing a definition for work and the principles of real work and virtual work. The lesson will continue with formulating the equations for strain energy. Calculating deflections by real work will be discussed and a systematic notation for deflections and the Law of Reciprocal Deflections will be developed.
This lesson will address calculating deflections by virtual work. The process for applying the principle of virtual work will be developed. Calculating deflections due to axial forces, shear and flexure will be covered as well as the relationship between flexural and shear deflections. The influence of temperature change on the structure will be introduced. Approaches for writing moment equations will be also reviewed.
This lesson will continue the discussion of deflection calculations and the principles upon which the various available methods are based. It will include discussion of direct integration, elastic weights, moment area, and conjugate beam. Slopes and deflections will be calculated at specific points on a beam span and slope and moment diagrams will be sketched. The use of the conjugate beam method for determining redundant moments will be introduced.
This lesson will continue the analysis of indeterminate structures by conjugate beam. Calculated deflections will be used with the method of consistent deflections to analyze indeterminate structures. The AISC 360-16 Specification for Structural Steel Buildings requirement that all deformations be considered in an analysis will be discussed and examples will be presented to illustrate the relative influence of these deformations on redundant forces and moments.
This lesson will continue the analysis of indeterminate structures. Analysis of indeterminate structures by the slope-deflection method will be developed using the principles previously developed for deflection calculations. Sidesway and non-sidesway frames will be presented and discussed. Approaches for modeling structures will be illustrated, including continuous beams and multi-story sway- and nonsway-frames.
The portal and cantilever methods of approximate frame analysis will be presented. The method of moment distribution will be introduced and the special approach for treatment of frames that exhibit sidesway will be presented. In addition, an approach that permits a somewhat independent checking of the moment distribution process will be developed.
This lesson will discuss the “modern methods” of analysis and illustrate how they may be understood and developed from the classical methods. It will also include a discussion of second-order analysis. The classical methods of analysis will be used in an iterative way to carry out a second-order analysis and to help explain the concepts of second-order analysis. The link between moment distribution and the approximate second-order analysis approach of AISC 360-16 Appendix 8 will be discussed.
