Generalized Optimal Active Control with Embedded and Half-space Soil-Structure Interaction
The paper presents an optimal active control algorithm with soil-structure interaction for seismic response. By using an intelligent device in the feedback gain matrix, the algorithm can...
Boundary Forcing and a Dual-Mode Calculation Scheme for Coastal Tidal Models Using Step-Wise Bathymetry
Tidal energetics are persistent and important factors in almost all coastal regions. As such, it is important to employ techniques that can consistently reproduce observed tidal variations....
Involving the Public to Reach Consensus in Water Resources Projects - An Interdisciplinary Perspective
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the reliability of the county's water supply in the event of an extreme emergency,...
Road to Recovery
The effect of the Loma Prieta earthquake on San Francisco's elevated viaduct system is still being felt more than four years later. Immediately after the quake, the entire...
A User Friendly Microcomputer Program for Liquefaction Potential Analysis
A user friendly microcomputer program is introduced to predict earthquake induced liquefaction and its associated settlement for level ground sites....
Seismic Analysis of Reinforced Concrete Building Using Finite-element Techniques
The response of a reinforced concrete building subjected to earthquake loading has been obtained on a personal computer using the finite-element code STARDYNE. For preliminary design,...
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
WAK and Full-Scale Load Tests on Granular Fill
For footings on granular fill that includes cobble- and boulder-size materials, in situ tests cannot be used to estimate foundation settlement because such fill is difficult to explore...
A Procedure for Predicting Seismic Deformation of Earth Structures
This paper presents an analysis procedure for predicting the earthquake induced displacements of earth structures. The procedure is an extension of the simple Newmark method from a single-degree-of-freedom...
Deformation of Sand Foundations Induced by Earthquakes
This paper discusses the deformation of sand foundations during earthquakes based on the experimental results of centrifuge tests. A group of tests was conducted on two types of buildings...
Model-Prototype Conformance of a Submerged Vortex in the Intake of a Vertical Turbine Pump
Submerged vortices are commonly found in sump intakes of vertical turbine pumps. These vortices are known to cause increased vibration and at times degrade pump performance. Approach flow...

Northridge: Questioning Our Codes
The earthquake that struck Southern California at 4:31 A.M. Pacific Time on January 17, 1994 was responsible for 61 deaths, more than 9,000 injuries and $30 million in damages. From its...
Seismic Retrofitting: Spending to Save
Seismic retrofitting work is most often concerned with saving lives. But in cases of infrastructure, or historic structures, saving the structure, and making sure that it can operate after...
GIS Application for Post Earthquake Investigation
The Post Earthquake Investigation Team (PEQIT) at the Office of Structure Design, Division of Structures, CALTRANS, has been organized since the 1971 San Fernando earthquake. It is an...
Validating a Citywide Traffic Planning Model
A traffic planning model can improve the public agency's ability to forecast future traffic and plan appropriate roadway intrastructure. However, the usefulness of these models depends...
Probabilistic Analysis of Faulting Associated with Earthquakes for Nuclear Waste Repositories
The probabilistic analysis of seismogenic faulting follows the same general methodology as the more common seismic hazard analysis for shaking. The main difference lies in the influence...
Probabilistic Seismic Design Considerations for a High-Level Nuclear Waste Repository
Earthquakes in the vicinity of an underground high-level waste (HLW) repository have potential effects that must be estimated during the design of the facility. The production facilities...
Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...
