Abstract: Several aspects of canopy flow are investigated. The problem of steady flow in a horizontally infinite canopy under neutral thermal stratification is treated theoretically. The resulting analytical model is then used as a ...

Abstract: The Hu-Washizu variational principle in linear elasticity in which displacement, strain, and stress can be independently varied is extended, for application to dynamic problems, to include independent ...

Abstract: The echelon matrix procedure is introduced, as a new base procedure for dimensional analysis, by its application to examples selected by previous authors. It is thereby shown that Buckingham's actual and very perceptive ...

Abstract: The monitoring of five precast, prestressed bridge girders during fabrication and service provided the opportunity to observe changes in camber over time. These camber variations were compared with corresponding strain and ...

Abstract: Hourly tethered-balloon wind soundings from the 650-m deep, narrow, Brush Creek Valley of Colorado are analyzed to determine the nocturnal atmospheric mass (or volume) budget of the valley. Under the assumption that the ...

Abstract: A collection of condition and appraisal ratings of bridges prior to collapse is presented and analyzed to show commonalities among collapsed bridges in New York State. General observations of bridge collapses are presented ...
