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...
GIS Plans Wastewater Future
When the Public Works Department began phase 3 construction on Albuquerque, N.M.'s current wastewater treatment plant in 1990, it was time to begin thinking about the next...
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,...
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...
Bridge Seismic Retrofit Prioritization
This paper describes a mathematical model developed to produce an index by which bridges in a network can be prioritized systematically for seismic retrofitting. The model incorporates...
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...
Seismic Hazard Along a Crude Oil Pipeline in the Event of an 1811-1812 Type New Madrid Earthquake
This paper presents an assessment of the seismic hazard that exists along a major crude oil pipeline (pipeline 22). An 1811-1812 type New Madrid earthquake with moment magnitude 8.2 is...
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...
Modeling Path Effects in the Los Angeles Region
Path effects for seismic wave propagation within three-dimensional (3-D) basin structures are analyzed using a reciprocal source experiment. In this experiment, a numerical simulation...
Earthquake Loss Estimation Modeling of the Seattle Water System Using a Deterministic Approach
This paper summarizes the project and resulting report entitled Earthquake Loss Estimation Modeling of the Seattle Water System (Ballantyne, 1990) conducted under funding from the United...
Evaluation of Techniques for the Seismic Modeling of Elevated Freeway Bridges
Following the October 1989 Loma Prieta earthquake in Northern California, a number of seismic parametric studies were performed for both two-level elevated freeways and single-column bridge...
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...
Effects of Cracking on Damping of Concrete Dams
A methodology is presented for dynamic analysis of concrete dams that considers the nonlinear stiffness and energy absorption effects of cracking. A cracking-consistent damping model is...
Continuum Modelling of Traffic Dymamics
Two new efficient higher-order continuum models are proposed to improve modelling of traffic dynamics. The new models do not require the use of an equilibrium speed-density relationship,...
