Dynamic Loading of a Rigid Frame Bridge
The objective of this paper is to investigate the dynamic response of a rigid frame bridge to two trucks (side by side) passing over the rough bridge deck. The rigid frame bridge is designed...
Continuity in Precast Prestressed Concrete Girder Bridges
An experimental study conducted to evaluate the behavior of pretensioned bridge members made continuous with a cast-in-place concrete slab and diaphragm is summarized. In this study, the...
Design of Box Girder Bridges by Nonlinear Theory
A modified design procedure applicable to a large number of conventional box girder bridges with longitudinally-stiffened flanges has been presented in this paper. It determines the ultimate...
Design Guidelines for the Use of Debonded Strands
In this paper, presented are the flexural tests performed on beams containing debonded strands. Results show that debonded strands can be used reliably and safely, stipulating that the...
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...
The Tatara Bridge - World's Longest Cable-Stayed Span
The Tatara Bridge now under construction has the main span length of 890m which will be the world's longest in cable-stayed bridges when completed. Except for certain lengths of prestressed...
Response of Stressed Timber T - and Box-Beam Bridges
The objective of this study is to establish the strength, stiffness, and transverse load distribution factors of stressed timber T-, Bulk T-, and Box-beam bridge systems. To achieve the...
AISI-FHWA Model Bridge Test
The Model Bridge Study involved a large experimental test program to evaluate the behavior of a 0.4-scale model of a two-span continuous plate-girder bridge with modular precast prestressed...
Bridge Evaluation Using a Hybrid Information System
The objective of this paper is to discuss the developments and implementation of a hybrid system consisting of a rule-based information system and hypermedia technology for use by inspectors...
Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...
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,...
Tests of Full-Size Pretensioned AASHTO Beams with Debonded Strands
A summary of an experimental investigation dealing with the effects of strand debonding on the flexure and shear behavior of simply supported pretensioned AASHTO beams with a cast-in-place...
Design of Half-Through or Pony Truss Bridges Using Square or Rectangular Hollow Structural Sections
The initial part of this paper will outline some of the research, testing, and investigation which has been done on half-through truss bridges. This research is primarily concerned with...
Innovations in Major Suspension Bridge Design
Before the Tacoma disaster, the trend in bridge-building is on increasing slenderness. But since its occurrence, a high degree of aerodynamic stability is required. Presented are designs...
Lightweight Concrete for a Segmental Bridge
Structural lightweight concrete can help increase the stiffness and decrease the mass of a bridge; both are qualities that make the structure more likely to survive an earthquake. Ordinarily,...
Analysis of I-Girder Highway Bridges
Analysis of a bridge superstructure is complicated by the general geometric and loading conditions. Presented in this paper are three dimensional finite element modeling techniques used...
Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....
Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...
An Assessment of the Joint Factor as Used in the Modified MEXE Method
The finite element method has been used to examine the joint factor in the modified MEXE method which is documented in the publications (BD21/93 and BA16/93) by the Department of Transport...
ESPADD.BR: Expert System Producing Automated Designs and Drawings for Bridges
This paper presents the logic and methodology used in developing an automated software system for designs and drawings of bridges. Its primary purpose is to design and draw highway bridge...
