Flow Behavior of Kinked Strip Drains
Due to the often expressed concern over the axial deformation of strip drains and the resulting impact on flow rate, this study has been undertaken. A laboratory experiment has been constructed,...
Survivability and Durability of a Nonwoven Geotextile
This paper presents the results of a field investigation and laboratory testing program to evaluate the properties of two different polypropylene, thermally-bonded nonwoven geotextiles...
Full Scale Foundation Trials on Grid Reinforced Clay
The paper describes the results of full-scale testing of strip footings on an alluvial clay site. Existing theory is briefly discussed but shown to be of little relevance to the consolidation...
Laboratory Study of Geogrid Reinforced Soil Walls
The paper describes the construction and testing of three (3) large-scale geogrid reinforced soil retaining wall models. The models were 3 m high and were built in the RMC Retaining Wall...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
New Parallel Wire Bundle for Cable-Stayed Bridges
A parallel wire bundle is described which is twisted with a long lay length. It is corrosion protected by an inner fill and outer coating of polyurethane. It presents a specially shaped,...
Frequency Domain Site Response with Pore Pressure
A frequency domain analysis for seismic site response and liquefaction potential is developed. The analysis is based upon a nonstationary random vibration theory. The model uses an effective...
Dependence of Fatigue Damage on Loading Amplitude Variability
Welded steel specimens have been tested under variable amplitude loadings to determine the extent to which fatigue life is affected by the rate of amplitude variability of the loading...
Statistics of Concrete Shrinkage Test Data
The paper reports a large series of concrete shrinkage tests which can be used for statistical purposes. The series involves two groups of 36 identical cylindrical specimens, with a diameter...
On Response Spectrum Approach for Nonclassically Damped Structural System
A response spectrum approach to approximate the maximum response of nonclassically damped structural systems is presented. The maximum response is expressed in terms of the sine spectrum,...
Bridge Reliability Evaluation Using 3-D Analysis and Damage Scenarios
This paper reports analytical investigations into the system strength and reliability evaluation of existing bridges using 3-D inelastic analysis and damage scenarios. In this context,...
Research Needs for Rational LRFD Criteria
There are at least a dozen factors causing or influencing impact. Current design specifications consider only a few of these. Location of truck wheel loads within the traffic lanes on...
Bridge Reliability?Evaluation vs. Design
Probabilistic methods of structural safety are being widely accepted as a basis for rationally considering uncertainties and developing reliability based design specifications for various...
Dynamic Maps for Seismic Risk Reduction and Effects of Soil Conditions
In order to perform useful vulnerability and risk evaluations, it is essential to have at one's disposal an automatic procedure of elaboration which provides answers in real time as soon...
A Stochastic Seismological Model in Earthquake Engineering
Recent studies of source mechanisms and wave propagation models enable one to generate strong motions based on deterministic source and source-to-site characteristics. The normal mode...
Practical Implementation of Seismic Probabilistic Risk Assessment
Many techniques for seismic probabilistic risk assessment have been developed by university researchers over the last decade. This paper reports on a study being conducted to determine...
Applications of ARMA Models for Seismic Damage Prediction
As an alternative to current design practice which is based on peak measured ground motions and scaled records from different events, individual earthquake records are treated as samples...
Actual Versus Assumed Behaviour of Girder Bridges
It is generally believed that the discrepancies between calculated and actual responses of bridges can diminish, to the point of being nonexistent, with refinement in the method of analysis....
Design Wind Loads for Broadcasting Antennas from Short Time Records
Very useful would be procedures for the determination of the design wind load on the basis of short time records, of duration comparable with the preliminary and/or design phases, so that...
Probabilistic Structural Response of a Turbopump Blade to Random Pulse Loading
The objective of this work is to develop probabilistic models of the response of a Space Shuttle Main Engine (SSME) turbopump blade to random impact loading. These loads are caused by...
