Coal-Gas Conundrum
Manufactured gas from coal brought streetlights and clean cooking fuel to the late Victorian era, but a hundred years later their legacy isn't quite so beneficial. Investigators...
Piles Over Problems Sites
It's increasingly difficult to find suitable space for construction in urban areas. Pile foundations can fill the void by making questionable and heavily regulated sites,...
Life in the Fast Track
Through innovative financing and skillful construction management, Oklahoma is proving that transportation megaprojects are still possible, even during an economic downturn. The result...
Project Management: Keys to Success
Successful construction projects can be traced to several key factors observed by the owner, the AE and the contractor. They include: 1) Goals and commitment of the managing partners agreed...
Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...
Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...
On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...
Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...
Experimental Photoelastic Analysis of Tunnels Containing Cracks
Due to the presence of cracks the strength of the structure is decreased in the present paper an experimental two dimensional photoelastic technique has been developed to analyze the circular...
Densification/Creep Behavior of Experimental Glass-Ceramic Waste Forms for Immobilization of High-Level Calcined Waste at the Idaho Chemical Processing Plant
A mixture of simulated high-level calcined waste (HLW) and Frit additives was hot isostatically pressed (HIPed) to a dense glass-ceramic waste form. A densification mapping software was...
Geoelectrical Tomography: Model Studies Related to Nuclear Waste Site Characterization
Borehole geoelectrical measurements offer a promising means for detecting and delineating resistivity anomalies in candidate geological formations being considered for underground storage...
Effect of Water on the Consolidation of Crushed Rock Salt
The consolidation behavior of crushed rock salt, as the backfill in the under-ground disposal of nuclear waste, will be important in controlling room closure rates and local permeability....
Anatomy of the Loma Prieta Earthquake Records of Two Steel Buildings Using MIMO System Identification
The Loma Prieta strong-motion records of a 4-story and a 47-story steel building are analyzed using system identification. A time variation study from the 4-story building records reveals...
Seismic Stability Analysis of Landfill
The failure mechanism of a waste containment system is not well understood due to the complexity and the heterogeneity of the system. The recent slope failure of the Kettleman Hills waste...
Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...
