Walls of Defense
During a bomb blast, most physical damage and injury occurs when exterior walls fail to protect building occupants. Exterior walls designed to withstand exterior blasts and to break away...
Casting Hot and Cold
Contractors and engineers battled the Minnesota winter to build a concrete segmental bridge with form travelers. Superstructure segments were poured in temperatures as low as -19F, using...
Smokestack Rescue
The site of an abandoned cement plant was transformed, via rehabilitation and new construction, into a $56 million retail and entertainment complex. The most prominent visual landmarks...
The Search for HPC (Available in Structural Engineering Special Issue only)
High-performance concrete (HPC) is often overlooked by engineers because its properties are not well documented. Concrete Clinic International conducted a study to learn more about the...
Coldhearted Building
A 20,000-ton district cooling plant owned by the Public Service Company of Colorado was recently built to sell chilled water to customers in downtown Denver who will use it to air-condition...
A Turnaround for Hangar Design
As the military's airplanes get larger and budgets get tighter, building hangars becomes more of a challenge. But by giving conventional rectangular hangar shapes a 90 degree...
Tracking Seismic Hazards
Union Station in downtown Portland, Ore. is a historic landmark but also a seismic risk. Engineers were charged with making a priority list of hazards so that the owners could prioritize...
Guidelines for Seismic Evaluation and Design of Petrochemical Facilities
These guidelines are intended to provide practical recommendations on several areas which affect the safety of a petrochemical facility during and following an earthquake. In the area...
Spatial Analysis in Soil Dynamics and Earthquake Engineering
This Geotechincal Special Publication contains the papers presented by the invited speakers in the sessions on Spatial Analysis in Soil Dynamics and Earthquake Engineering held during...
Seismic in St. Louis
Following collapse of sections of the double-deck I-880 Cypress Viaduct in the 1989 Loma Prieta earthquake, the Missouri Department of Transportation initiated a seismic evaluation and...

General Procedures for Conducting an Investigation
This section covers general procedures for conducting an investigation. Topics include lifelines and critical facilities to be investigated; the role of the team leader; getting started;...
Shear-wall Retrofit
With the effects of the 1989 Loma Prieta earthquake still lingering and another quake looming sometime in the future, engineers faced with retrofitting the Pacific Gas & Electric...
Blasting Densifies Volcanic Debris (Available only in
The relatively new ground improvement technology of blast densification overcame soil problems posed by volcanic ash at Mount St. Helens National Volcanic Monument. In 1993 WSDOT began...
Automatic Control of Flocculation Processes
A control system for flocculation, used in water and wastewater treatment operations is being developed. The approach is based on detailed particle size distribution measurements of influent...
Analyzing Drought with a Simplified Climate Model
A simplified climate model with combined atmospheric-hydrologic processes has been developed at the University of California Davis for the study of physical processes related to drought....
Preliminary Studies of a Karst Warm Spring in Mt. Kr?uterin, Austria
A warm spring occurs at the west foot of Mt. Kruterin, characterized by relatively higher temperature (17.4?C) and sulfate concentration (162 mg/L) against with the regional background...
Debris Flow Events at Mountainous Creeks near Santiago, Chile- Hydrologic Analysis
One of the most important aspects in relation to peak flows magnitudes generated in mountainous catchments at the western side of the Andes facing the city of Santiago, Chile (latitude...
Uncertainty Analysis of Reservoir Sedimentation
In estimating reservoir sedimentation, a number of uncertainties arise. These are related to annual streamfiow, sediment load, sediment particle size, trap efficiency, and reservoir operation....
