The first project in America to use friction damping was approved by the City of Los Angeles for the retrofit of a 10-story concrete frame building, designed to resist a Maximum Credible...
Seismic Response and Retrofitting of Non-Ductile Reinforced Concrete Bridges
The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the...
Utilizing Visco-Elastic Dampers in the Seismic Retrofit of a Thirteen Story Steel Framed Building
A 13 story steel framed building in Santa Clara Country, California exhibited strong beating effects (torsional coupling) and prolonged building response as result of various seismic events....
Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...
Space Frame Solution for the Design of Large Pyramid Structures
This paper presents the engineering design methodology, structural analysis, system detailing, and installation procedures for a large span space frame structure currently under construction...
Assessing Effects for Disposal Sites off San Francisco
A simple particle tracking model has been used to estimate the size of deposition footprints and transient turbidity effects in the water column resulting from disposal of dredged material...
Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...
Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...
Instrumented Buoy Network Response to Ocean Swell
The National Data Buoy Center has an extensive network of more than 20 moored buoys along the west coast of North America And in the Eastern North Pacific Ocean. The network ranges from...
Wave Monitoring in The Southern California Bight
An overview of recent research by the Coastal Information Program (CDIP), aimed at effectively monitoring wave conditions in the Southern California Bight, is presented. The topographic...
An Offshore Island Wave Sheltering Model
The wave climate along Southern California Coastal area is greatly modified by the existing systems of natural islands shown. As deep water wave approach the nearshore area, they generally...
California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...
Managing Reservoir Storage for Fish Production
Salmon populations in numerous Pacific Coast rivers are in decline and are in danger of becoming threatened or endangered. A reservoir system simulation model was developed for the Trinity...
Effects of Lateral Heading Flow Steadiness on Lateral Spillage
Hourly inflow and spillage rates from three lateral canals in the Imperial Irrigation District in Southern California were measured for seven months and subsequently analyzed to identify...
Effects of Climate Change on Water Quality
This research explores the potential effects of climate change on the quality of waters in lakes. Temperature and dissolved oxygen were considered the primary water quality variables due...
Modeling Temperature Impacts on Salmon Survival
Among research goals at the University of California-Davis are the development and application of mathematical models to study water quality impacts on threatened and endangered species....
Impacts of Natural and Manmade Changes on the San Luis Rey River Environment
Almost all rivers continually change their position and shape based on various geomorphic and hydraulic factors, caused by natural as well as manmade activities on the riverine environment....
Addressing Central Valley Project Policy Issues Using a General-Purpose Model
The U.S. Bureau of Reclamation's Central Valley Project (CVP) in California is constantly undergoing changes in legal mandates and policy objectives. Due to the complex nature of existing...
Involving the Public to Reach Consensus in Water Resources Projects - An Interdisciplinary Perspective
