Hardy Cross Papers (Digital Surrogates)

Hardy Cross Papers (Digital Surrogates), 1930, contains a digitized copy of Cross' paper "Analysis of Continuous Frames by Distributing Fixed-end Moments" included in the May 1930 Proceedings of the American Society of Civil Engineers. This paper contributed refining and simplifying the mathematical work required to analyze elements of statically indeterminate buildings and bridges. It was one of Cross' major contributions to the field of structural engineering, and reshaped formal structural analysis for the next 30 years until computers started to enter the scene; his paper of eight pages on moment distribution led to 144 pages of discussion. The digitized copy includes an autograph of Hardy Cross in the front page.

Materials also include .JPG images of Cross' article, divided by page. Access to these images is available upon request.
