Motivation

• The developement of this educational tool was motivated by an excellent text book by Richard White, Peter Gergely, and Robert Sexsmith from Cornell University: Structural Engineering, vol. 2, John Wiley, 1976. The image below, which was scanned from that book, says by itself. In the book, the Moment Distribution Method, devised by Hardy Cross ("Analysis of Continuous Frames by Distributing Fixed-End Moments," Transactions, ASCE, Paper no. 1793, vol. 96, 1936), is explained with the aid of a physical experiment shown in this image. The e-Cross program made available in this web site may be seen as a virtual version of this experiment.

Revisions

• Version 1.01: Fixed display of moment distribution coefficients in Solution Canvas. In version 1.00, the left and right coefficient values at each internal node were swapped. The solution was correct, the mistake was only in the display of coefficient values.
