concrete bridge deck damage detection by measurement and monitoring variables related to vibration signatures is one of the main tasks of any bridge health monitoring system (bhms). generally damage puts some detectable/discoverable signs in the parameters of bridge vibration behavior. however, differences between frequency and mode shape before and after damage are not remarkable as vibration ...

This paper presents a numerical study of the structural behaviour of concrete bridge deck slabs under static patch loads and dynamic traffic loads and an investigation of compressive membrane action (CMA) inside slabs. Those deck slabs were reinforced with Glass Fibre Reinforced Polymer (GFRP) bars. Non-linear finite element analysis (NLFEA) models were established using ABAQUS 6.10 software pa...

By a well-known result of Bayer and Diaconis, the maximum entropy model of the common riffle shuffle implies that the number of riffle shuffles necessary to mix a standard deck of 52 cards is either 7 or 11 — with the former number applying when the metric used to define mixing is the total variation distance and the later when it is the separation distance. This and other related results assum...

Highway bridges are frequently constructed as simple span structures with steel or concrete girders and a cast-in-place concrete deck, spanning from one pier to another. At each end of the simple span deck, a joint is provided for deck movement due to temperature, shrinkage, and creep. Bridge deck joints are expensive and pose many problems with regard to bridge maintenance. Elimination of deck...

The paper describes the extension of a Monte Carlo based damage stability simulation method for generation approval documents both statutory and operational stability. intention this development is that advantages concept can be used without necessity to ask alternative design procedures during by classification society. This means same documentation must generated as conventional calculation. ...

Unsafe acts of ship officers have been a direct cause many maritime accidents. In the industry, much effort has made to prevent unsafe and improve safe behaviours officers. The positive effect organizational safety climate on human behaviour well documented in literature. Within this context, paper aims pioneer development measurement constructs shipping operations analyze its impact consciousn...

In the framework of EU project Flooding Accident Response (FLARE), flooding mitigation on a RoPax ship was studied using different active methods to improve safety in damage cases leading hull breach and flooding. Adding control systems designs ships service, which would mitigate effects case, could be an attractive way safety. order promote this idea, such measures were studied: choice them, r...

The threat to safety of aging bridges has been recognized as a critical concern to the general public due to the poor condition of many bridges in the U.S. Currently, the bridge inspection is conducted manually, and it is not efficient to identify bridge condition deterioration in order to facilitate implementation of appropriate maintenance or rehabilitation procedures. In this paper, we repor...

Cattle transportation by commercial truck carrier is common in the United States, and often cattle are placed within 1 of 8 potential compartments within the truck for the journey. The objective of this research was to determine potential associations between animal wellness (as measured by ADG and health outcomes) during a relatively short backgrounding phase (46.6 +/- 8.5 d) and location with...
