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...
Degradation of Natural Building Stone
This proceedings,
Comparison of Blast and Earthquake Effects on Reinforced Concrete Frame Structures
This chapter compares the damage done by an explosive blast and an earthquake....
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...
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...
Lake Number: A Long-Term Lake Water Quality Predictor
A seasonal maximum Lake number was found to be a good predictor for volume averaged water temperatures, maximum water temperatures near lake bottom, seasonal stratification characteristics,...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
Karst Water Inventories Using Thermography
An airborne thermal camera was used to locate springs, swallets, and caves in a karst watershed. The detector was an imaging infrared camera with a temperature sensitivity of approximately...
Modeling Combined Stresses on Aquatic Ecosystems
A mechanistic ecosystem response model is being developed by incorporating exposure/response relationships for selected natural and anthropogenic stresses into an existing hydrodynamic...
Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...
Shake, Rattle and Map
Researchers at Stanford's Earthquake Engineering Institute are developing an innovative system that uses geographic information systems to predict earthquake damage. A case study shows...
Quake Proofing a Palace
A $36.5 million renovation of the California Palace of the Legion of Honor included a two-level underground expansion on a very sensitive site and the largest-ever seismic retrofit for...
Bad Vibrations
Insurance companies often hire engineers to investigate homeowner claims of damage caused by vibrations near a blast or construction site. But these engineers often lack the background...
