Abstract: This paper examines demographic, economic, and sociotechnical trends to the year 2050 that will shape future demand for buildings. It uses historical data and projections from the United Nations and other authoritative ...

Abstract: The objective of this study was to examine the elastic behavior of Douglas fir in the radial‐longitudinal plane. Parallel‐ and perpendicular‐to‐grain tensile test results were used to establish linear elastic behavior. ...

Abstract: This study investigated the tensile strength of Douglas-fir loaded at an angle to the grain. Strength was determined for grain angles of 15, 30, 45 and 60 degrees in the radial-longitudinal plane. Strength was found to ...

Abstract: The three-dimensional tidal circulation in an elongated basin of arbitrary depth is described with a linear, constant-density model on the f plane. Rotation fundamentally alters the lateral flow, introducing a lateral ...

Abstract: Coastal downwelling events, induced by tropical storms which travel up along the coast, occur regularly during the summer over the shelf of Southern California. Large vertical velocities (0.5 cm s?1) are observed over the ...

Abstract: An unexpected, but explainable, web buckle occurred during the field testing of the I-40 bridge over the Rio Grande in Albuquerque, N.M. The three-span continuous steel plate-girder bridge had a defect (physical cut) ...

Abstract: The three-dimensional residual circulation driven by tides in an elongated basin of arbitrary depth is described with a small amplitude, constant density model on the f plane. The inclusion of rotation fundamentally alters ...

Abstract: Fluctuations in the atmospheric ozone column may significantly increase mean transmitted ultraviolet radiation at biologically sensitive wavelengths, and increase mean photodissociation rates in the lower stratosphere.
