TL;DR: In this article, a simple and elementary method is developed which permits one to calculate lower limits of strength and rigidity of lateral support in order to provide full bracing to columns and beams.
Abstract: Simple and elementary method is developed which permits one to calculate lower limits of strength and rigidity of lateral support in order to provide full bracing to columns and beams; full bracing is defined as equivalent in effectiveness to immovable lateral support.

TL;DR: In this paper, the relative effects on friction factor of flow of suspended sediment load and configurations which form on sand beds of streams were investigated, and it was shown that the reduction of friction factor due to changes in bed configuration is much larger than that due to suspended sediment.
Abstract: Experiments were made to determine relative effects on friction factor of flow of suspended sediment load and configurations which form on sand beds of streams; results showed that friction factor of stream carrying suspended sediment is less than comparable one without sediment; reduction of friction factor due to changes in bed configuration is much larger than that due to suspended sediment.

TL;DR: In this article, the buckling of flanges and webs of WF-beams during the formation of plastic hinges was examined and it was shown that such severe conditions made the re-examination of the problem difficult.
Abstract: Plastic design methods assume that local buckling of flanges and webs of WF-beams will not occur during the formation of plastic hinges. Such severe conditions made the re-examination of the proble...

TL;DR: In this article, a study of the properties of glacial lake clays was conducted and the shearing resistance and sensitivity were found to be intimately related to the structure of the clay as well as the stress history.
Abstract: This article reports on a study of the properties of glacial lake clays. Data collected from a number of sites in the Great Lakes area of the United States are presented. Despite local variations in subsoil conditions and the large distances between the sites, the clay deposits investigated have much in common and it is possible to study them as a related family. An analysis was made of the principal factors that control the strength characteristics of the clays. The shearing resistance and sensitivity were found to be intimately related to the structure of the clay as well as the stress history.
