Ground-Water Modeling Without Fear
Computerized ground-water modeling has leapt from the cloistered laboratory to the field project as more and more programs are written for the personal computer. These easy-to-understand...
Pounds, Kilos and Newtons
In the U.S., an aura of mystery, like the glamour afforded the medieval priest by his mastery of Latin, surrounds the Syst�me International. This unreasonable awe, largely generated by...
Recent Advances in Cone Penetrometer Measurements (Software and Hardware) and Its Application to Liquefaction Susceptibility
Some of the recent advances made in Cone Penetration Test (CPT) data acquisition system and real time processing of CPT data are presented. A key component of the new CPT data acquisition...
Electronic Data Acquisition and Analysis for Soil Dynamics Applications
Recent advances in micro-computer-based data acquisition hardware and software systems have created a window of opportunity for the soil dynamics specialist. Increases in the number of...
Use of Bender Elements in Soil Dynamics Experiments
Transducers employing piezoelectric bender elements have been found to be versatile sources and receivers of small-amplitude shear waves, with multiple potential applications. The constitutive...
Use of Piezoceramic Bender Elements in Soil Dynamics Testing
The use of piezoceramic bender elements is described to measure small strain, shear wave velocity distributions in soil models used in centrifuge and shake table testing. Experimental...
Computing in Civil Engineering and Symposium on Data Bases
This proceedings consists of the papers presented at the conference Computing in Civil Engineering and Symposium on Data Bases held in conjunction with A/E/C Systems '91 from May 6-8,...
Mechanics Computing in 1990's and Beyond
This proceedings,
Out of the Lab...and into the Field?
Materials experts know very little about concrete's basic structure. Now, though, engineers at a research center sponsored by the National Science Foundation are working on...
Earthquake Considerations in Design of the Los Angeles Metro
This paper discusses the earthquake design of the Los Angeles Metro. The design earthquake parameters are presented and discussed in light of the behavior of buried structures subjected...
San Francisco Double-Deck Viaduct Retrofits
Following the Loma Prieta Earthquake in October 1989, six double-deck reinforced concrete viaducts in San Francisco were closed because of some isolated damage, and as a precaution for...
Regional Risk Assessment of Environmental Contamination from Oil Pipelines
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks due to earthquakes. Risk is measured both as volume of oil released and...
Aseismic Calculations for Transmission Towers
In this paper, mechanical models for long-span transmission line systems under elastic and gravitational restoring forces are established in three different directions; this continues...
A Study of Shield Tunnel's Earthquake Prevention Under a Big Earthquake
Currently, the most commonly used approach for determining the aseismicity of a shield tunnel is the 'Response Displacement Method.' This is based on analysed...
Earthquake Response of Liquid-Filled Pipeline at Finite Depth Below Ground Surface
This paper deals with the problem of earthquake response analysis of pipelines, empty or fully filled with liquid and buried at a finite depth below the ground surface. Emphasis is placed...
Seismic Analysis of Buried Pipelines Subjected to Vertical Fault Movement
Earthquakes have demonstrated the vulnerability of buried pipelines, mainly to 'non-dynamic' seismic deformations of the ground, such as liquefaction, landslide...
GIS-Based Interactive and Graphic Computer System to Evaluate Seismic Risks on Water Delivery Networks
As interactive and graphic computer system to evaluate seismic risks of an arbitrary water delivery network is developed, based on G/S (geographic information system) software, ARC/INFO....
Seismic Reliability Analyses of Large Scale Lifeline Networks
For assesing the seismic reliability of large scale lifeline networks we developed an algorithm which had only polynomial complexity to enumerate paths in the network. Using this algorithm...
Stochastic Responses of Lifeline Systems Under Seismic Excitations
A wave superposition model is proposed to predict the field motion on the basis of the seismic records obtained from a strong motion array. By assuming the ground motion to be a homogeneous...
