RISLessons Learned from Commercial Activities Competitions
Publisher: American Society of Civil Engineers
Abstract: Many lessons have been learned as more and more portions of the federal work force have become subject to commercial activities competitions in an effort to make them more efficient. These lessons are becoming increasingly ...
Percolation Threshold of Sand-Clay Binary Mixtures
Publisher: American Society of Civil Engineers
Abstract: Many poorly graded granular materials of engineering importance can be characterized as gap-graded binary mixtures. Such mixtures display a volume-change response at a threshold value of the coarse fraction that is reminiscent ...
Hydraulic Conductivity of Geosynthetic Clay Liners Exhumed from Landfill Final Covers with Composite Barriers
Publisher: American Society of Civil Engineers
Abstract: Geosynthetic clay liners (GCLs) were exhumed from composite barriers, (i.e., geomembrane over GCL) in final covers at four sites after 4.7 to 6.7 years to evaluate the in-service condition. Monovalent bound cations were ...
Application of Fatty Acid Based Phase Change Material to Reduce Energy Consumption From Roofs of Buildings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Buildings account for a significant portion of the total energy consumption in the U.S., especially the energyinefficient commercial building sector. As part of the future path toward realizing net zero energy buildings, ...
Polymer Fouling and Hydraulic Conductivity of Mixtures of Sodium Bentonite and a Bentonite-Polymer Composite

A Search for Chaotic Behavior in Stratospheric Variability: Comparison between the Northern and Southern Hemispheres
Publisher: American Meteorological Society
Abstract: outhern Hemisphere (SH) stratospheric variability is investigated with respect to chaotic behavior using time series from three different variables extracted from four different reanalysis products. The results are compared ...
Displacement-Based Design of Slender Reinforced Concrete Structural Walls—Experimental Verification
Publisher: American Society of Civil Engineers
Abstract: Application of displacement-based design for slender structural walls results in predictions for the wall normal strain gradient derived from estimating the wall neutral axis depth and maximum compressive strain at the ...
Seismic Design of RC Structural Walls. Part II: Applications
Publisher: American Society of Civil Engineers
Abstract: Design calculations are presented for two shear-wall buildings using a new code format described in a companion paper. The lateral force resisting system for building 1 is comprised of two rectangular and two channel-shaped ...
Laboratory Simulation of Wind Vibrations in Roadside Structures
Publisher: American Society of Civil Engineers
Abstract: A method of frequency domain analysis in a laboratory is presented for simulating wind vibration affecting roadside transportation structures. The approach is intended to be complementary to or in lieu of a test in a ...
Hydration and Cation Exchange during Subgrade Hydration and Effect on Hydraulic Conductivity of Geosynthetic Clay Liners
Publisher: American Society of Civil Engineers
Abstract: Experiments were conducted to evaluate cation exchange during hydration of geosynthetic clay liners (GCLs) used in composite hydraulic barriers and the effect on their hydraulic conductivity. GCLs arranged in a composite ...
