COMPUTATIONAL FLUID DYNAMIC ANALYSIS OF HIGHWAY BRIDGES EXPOSED TO HURRICANE WAVES

FE Based Vulnerability Assessment of Highway Bridges Exposed to Moderate Seismic Hazard

Nonlinear ship waves and computational fluid dynamics

Research works undertaken in the first author's laboratory at the University of Tokyo over the past 30 years are highlighted. Finding of the occurrence of nonlinear waves (named Free-Surface Shock Waves) in the vicinity of a ship advancing at constant speed provided the start-line for the progress of innovative technologies in the ship hull-form design. Based on these findings, a multitude of t...

Computational fluid dynamic analysis of intracranial aneurysmal bleb formation.

BACKGROUND The management of unruptured aneurysms is controversial, with the decision to treat influenced by aneurysm characteristics including size and morphology. Aneurysmal bleb formation is thought to be associated with an increased risk of rupture. OBJECTIVE To correlate computational fluid dynamic (CFD) indices with bleb formation. METHODS Anatomic models were constructed from 3-dimen...

Computational Movement Analysis Using Brownian Bridges

Widespread availability of location tracking devices leads to a rapidly increasing amount of movement data and to the need to analyse these data. These data typically consist of location measurements taken at discrete times, often with a non-negligible error margin in the measured locations. A low sampling rate leads to high uncertainty of the locations between the times at which these measurem...

Live load model for highway bridges *

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...
