Comparing exact vs. portal vs. cantilever methods of approximate analysis results
Virtual work -- temperature change and defect (length mismatch) examples
Virtual work -- camber due to temperature gradient [extra handout]
Application of principle of virtual work to find displacements in statically indeterminate structures; truss example
Planar frame element stiffness coefficients derivation and expressions for member deflected shape (shape functions related to member end transverse displacements and rotations)
Stiffness matrices for planar frame, beam, and truss elements
Using stiffness method in the presence of internodal loading (additional examples; more examples)
Effects of axial forces on flexural stiffness [extra handout]
SAP2000 handout and limited duration educational version of the software (warning: 600MB file)
Example application of portal method and cantilever method of approximate analysis
Simply supported beam shear + bending moment diagram examples
Beam shear and bending moment diagrams for various loading cases (by NDS)
Application of virtual force method to find displacement in a statically indeterminate beam
Application of virtual force method to find displacement in a statically indeterminate truss
On the Method of Complementary Energy by Westergaard (1942)
Geometrical aspects of optimum truss like structures by Mazurek, Baker, and Tort
Examples of influence lines for statically indeterminate beams by Bisarnsin (shows how one can draw them and obtain the ordinates!)
Stiffness Method - Two Examples
On Analysis and Design by Cross
The Column Analogy by Cross
Remembering the Column Analogy by Sozen -- on the column analogy approach developed by Cross to find fixed-end moments of single-span beams
The collection of classnotes on Statically Indeterminate Structures by Cross and Morgan
PocketStatics -- for MS Windows and PocketPC (get the trial version and play; see the instructor for extended use registration code)
PocketStatics on the NEES hub (if you have access to the Internet and can run Java, you can use PocketStatics on the NEES hub! Requires registration for a NEES hub account --registrations are free and takes only a minute)
SAP2000 v7.4 student version (55 MB zip file)
GOYA - Truss and frame analysis software by Drs. Ichinose and Sozen
West Point Bridge software (fun to play with)
Google SketchUp (3D modeling software -- so easy to use and it is free!)
A typical software bug-message in the world of structural analysis/design -- not to berate the particular software company, but to give you a flavor of misses and messes. So, beware; at times, it could be worse than garbage in-garbage out.
Reports of trial designs -- set 1 and set 2 (from Structural Engineering Institute) -- designs are not born equal
Historical outline of matrix structural analysis by C.A. Felippa
Degrees of freedom of plane and space frames (for FAIR USE ONLY) -- a paper that might of interest. It is about degrees of static indeterminacy, not kinematic degrees of freedom.
An investigation of the interaction of reinforced concrete frames with masonry filler walls by A.E. Fiorato, M.A. Sozen, and W.L. Gamble.
E-Defense (World's largest shake-table) and the test movies
Question: Is an exact analysis of an approximate model an approximate analysis of the exact model?
"All analyses are based on some assumptions which are not quite in accordance with the facts. From this, however, it does not follow that the conclusions of the analysis are not very close to the facts." - H. Cross.
"It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not seek for exactness where only an approximation is possible." - Aristotle
"One pound of learning requires ten pounds of common sense to apply it." - Persian proverb.
