Seismic Response Studies on a Two Span Slab-On-Girder Bridge
A new type of self-equilibrating snap-back (quick-release) test setup is employed to investigate the transverse dynamic response of a two-span continuous slab-on-girder highway bridge....
Seismic Performance of Railway Bridges
Historically, the seismic performance of railway bridges in the U.S.A. has been very satisfactory during earthquakes of this century. There are many possible factors contributing to this...
Seismic Research Program for Highway Construction
This paper provides an overview of the highway research program being conducted by the National Center for Earthquake Engineering Research (NCEER). This six-year program, which is sponsored...
A Study of Jointless Bridge Behavior
The pressing need for maintenance free and low construction cost bridges, has increased the interest and activity in building integral or jointless bridges. The investigation of the behavior...
LRFD Provisions for Wood Bridges
A project to develop a load and resistance factor design (LRFD) edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway...
Development Length of Uncoated Prestressing Strand
The Federal Highway Administration is conducting ongoing research which investigates the development length of uncoated and epoxy coated prestressing strand in prestressed concrete members....
Construction of the Baytown Bridge, Houston
Connecting Baytown and LaPorte, the Baytown Bridge is a twin structure with four traffic lanes each. Its structure is designed as a cable-stayed bridge with concrete towers and composite...
Horizontally Curved Steel Bridge Research-Update 2
Theory and data necessary for the development and calibration of an LRFD based curved steel bridge specification do not presently exist. To address these needs, the Federal Highway Administration...
Current and Future Research in Steel Bridge Structures
The topics I have listed are ones which I am aware through discussions with various researches, designers, and industry representatives. The list of topics is presented as a starting point...
Instrumentation and Testing of a Three Hinge Arch for Service Loads Increase
A three hinge arch railroad bridge was instrumented and tested to evaluate its condition and the required modification for increasing the service loads. Initially the structure was designed...
Field Tests of Railway Bridges
A research program focused on the evaluation of railway bridges has been underway for the past five years. The objectives of a research are as follows: (1) determine the loading spectra...
Condition Assessment of Highway Bridges
An application of modal testing and structural identification in the condition assessment of bridges is presented. Damage definition and conceptualization is discussed. Damage detection...
Acoustic Emission Monitoring of Steel Bridges
Global nondestructive monitoring techniques are of great significance for rapid monitoring of bridges. One promising technique involves monitoring the microseismic events (Acoustic Emissions,...
Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...
Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...
Three Dimensional Modelling of Estuarine Sediment Transport
This paper describes the sediment transport module in the three-dimensional finite element model TELEMAC-3D which uses the operator splitting technique to solve the shallow water and transport...
A New LAX-WENDROFF Algorithm to Solve the Bed Continuity Equation With Slope Effect
The numerical simulation of mobile bed evolutions of seas, estuaries and rivers requires a morphological model, including the effects of waves, currents and sediment transport, as well...
Effects of Flocculation on Particle Transport
On the basis of previous experimental and theoretical work on flocculation rates and the settling speeds of flocs, an accurate and computationally efficient model of the aggregation and...
The Formation of a Turbidity Maximum in an Estuary
In the present study, a numerical model is used to investigate the transport of sediments in a stratified estuary. The model includes sediment resuspension and deposition as well as three-dimensional,...
