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,...
Optimal Resource Leveling Using Integer-Linear Programming
The project manager strives to schedule various project tasks as efficiently as possible. But, resources available to the project manager are limited. A problem arises when a schedule...
