Time-Dependent Nonlinear Analysis of Cable-Supported Prestressed Concrete Bridges
A method of analysis and a computer program CFRAME for the material and geometric nonlinear analysis of cable-supported planar prestressed concrete bridges including the time-dependent...
Finite Element Analysis and Design of Bridges with Applicatrons of ICAD
This paper describes applications of client-server models, interprocess communications (IPC), and concepts of intelligent CAD (ICAD) to the interactive design and analysis of highway bridge...
Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...
Finite Element Representation of Approach Slabs
Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area,...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
A New Approach for Road Network and Bridge Planning
Road networks usually include a large number of bridges and tunnels. The locations of these bridges and tunnels are decided by the road planner during the design of the road alignment...
The San Andreas Fault System, A Multimedia Earthquake Encyclopedia
The objective of this paper is to present the current efforts underway towards the development of the first multimedia earthquake encyclopedia. This is an attempt to use the treasury of...
Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...
Combined Boundary Element and Finite Element Analysis of Composite Slab on Girder Bridges
In this paper, the coupling of boundary element and finite element methods and its application to analyze slab on girder bridges are studied. The boundary element method (BEM) is employed...
A Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...
Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
A Constraint-Based Composites Design Advisor
Most engineering problems, because they involve mathematical relations (constraints) on real valued quantities (objects), can be reduced to constraint networks. The authors speculate that...
Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...
Non-linear Analysis of a Cable Stayed Bridge
A concrete single-pylon cable-stayed bridge has been analyzed to investigate the ultimate capacity. Two different methods were used to investigate the nonlinear behaviour. First, a simplified...
Decision Methods for Selecting Earth Retaining Structures
The Bridge Branch of the Colorado Department of Transportation (CDOT) has organized the framework of a formal decision process for retaining wall selection. The process facilitates implementation...
Benefit-Cost Analysis for Optimal Budget Allocation to Bridges
The funding available for bridge improvements in the United States has been insufficient for many years. The limited budgets granted have generally been allocated based on Sufficiency...
NCHRP Project 12-28(2)A Bridge Management System Software
This paper describes the various features of the bridge management system being developed by NET Corporation as part of a project funded by the National Cooperative Highway Research Program...
Bridge Management System Implementation at CALTRANS
Development of a new generation of Bridge Management System (BMS) capabilities has been a high priority for CALTRANS for the past four years. Although the Department has had a bridge inventory...
CAD System for Structural Aesthetics of Bridge Form
An exploratory design process for aesthetic bridge structure is proposed in this paper through developing a prototype of comprehensive CAD system. This process is conceived not only for...
