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...

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,...

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...

Plastic Limit Analysis of Arch Dams
