Seismic Behavior of Long-Span Cable-Stayed Bridges
Special features of the earthquake-response analysis of cable-stayed bridges, subjected to multiple-support excitation, are presented including a basis for calculation of seismic forces...
Seismic Response Analysis of Two Major Bridge Structures
The seismic response analyses of two major bridge structures have been conducted. In these two bridges, portions of the piles are either submerged in the water or free-standing within...
The Earthquake Barrier
The earthquake barrier protects buildings from the horizontal ground vibrations of an earthquake by installing a 'force barrier and an energy barrier' at the...
Comparative Seismic Response of Damped Braced Frames
The behaviours of braced steel building frames with friction joints and with eccentric bracing, under seismic forces, are compared. Nonlinear time history dynamic analysis is used. Friction...
Nonlinear Response Combination in Seismic Analysis
Simple, approximate methods are developed to evaluate the maxima of response measures which are nonlinear functions of modal responses to seismic input. Examples for such response quantities...
Ambient Vibration Testing of the Foothill Communities Law and Justice Building
This paper presents the results of two ambient vibration tests conducted on the Foothill Communities Law and Justice Center Building. One ambient test was performed in 1985. The second...
Blasting Densifies Sand
Constructing the Jebba Dam on Nigeria's Niger River required in-place densification of large volumes of loose sand to record depths of up to 131 ft. Vibrocompaction was used...
Lifeline Seismic Risk Analysis?Case Studies
These papers employ design concepts and procedures in lifeline seismic risk analysis. Two of the papers describe the seismic hazards in the northwestern United States. A systems model...
Physics-Based Modeling of Lakes, Reservoirs, and Impoundments
This book provides an overview of considerations that apply to modeling flow and transport in lakes, reservoirs, and impoundments using equations based on conservation principles. Specific...
Landslide Investigations Using the Weight Penetrometer
The weight penetrometer is a light weight device and can be easily deployed on slopes not accessible to conventional exploratory tools such as drill rigs or cone penetrometers. The weight...
Strength of Fine-Grained Soils Using the Piezocone
Evaluation has been made of several theories and methods for deducing the undrained and effective stress strength of saturated fine-grained soil from piezocone test results. Bearing capacity...
Laboratory and Field Evaluation of Cone Penetrometers
Cone penetrometers from 8 organizations have been studied by performing laboratory tests and field tests. The testing show that pore pressure and temperature zero shift affect significantly...
Effctive Stress Interpretation of In-situ Tests
Significant differences in terms of load-settlement curves obtained from Plate Load Tests (PLT) and q//c profiles obtained from Static Cone Penetration Tests (SCPT) at two sites with different...
Heat Treatment and Low Pressure Oxidation Systems
A study was performed to identify problems and to document solutions in the design, operation, and maintenance of heat treatment and low pressure oxidation systems for conditioning sludge...
Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...
Future Hydrothermal Power of the United States
Public indignation toward nuclear-power expansion, and dwindling oil and gas reserves dictate the needs to look for alternative-power sources, such as coal and water. It is a prime time...
Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...
ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
Recently developed Applied Technology Council (ATC) methodology and data provide a technical basis for rapid assessment of structure seismic vulnerability. Methodology developed under...
Evaluation of the Seismic Performance of Buildings
The aim of the paper is to present the different existing methodologies available for the assessment of seismic damage to buildings. The approach aims towards the development of a mini-computer...
Techniques for Estimating Earthquake Probable Loss for Buildings and Contents
The probable maximum loss (PML) is useful for quantifing the seismic risk exposure of a facility and for rational decision making regarding earthquake insurance and seismic strengthening...
