Deterioration of bridges under repeated traffic loading has called attention to the need for improvements in the understanding of vehicle–bridge interaction. While analytical and numerical models have been previously explored to describe the interaction that exists between a sprung mass (i.e., a moving vehicle) and an elastic beam (i.e., bridge), comparatively less research has been focused on ...

Bridge life cycle maintenance costs can be estimated more accurately if the deteriorating and maintaining process can be simulated objectively. This paper first proposed a reliabilitybased model for prediction of deterioration. The performance of bridge elements was quantified by the reliability index. A stochastic approach was then introduced and the probabilities for what action should be tak...

a new design for replacing a missing anterior tooth is described. in this article, a lingually fixed partial denture, its advantages, disadvantages, indication and contraindications have been explained. the ability of this design to replace a single missing central or lateral incisor is discussed.

Bridge deterioration is affected by various factors. However, neither the relationships between these factors and are explicitly determined, nor relative effect of each factor on well understood. This study proposed a methodology to resolve issues integrating an artificial neural network (ANN) sensitivity analysis method. The ANN was used predict deterioration, method applied evaluate influence...

Bridge censored databases can be used to analyze and assess structural deterioration conditions, but conducting the analysis is difficult. This difficulty occurs because many factors affect deterioration, time span of data for these depends on years in service respective bridge. In addition, values some are not regularly observed. The present study uses long short-term memory (LSTM) consider tw...

This paper presents a reliability-based optimization model of inspection, maintenance, and replacement for a system of several highway bridges. The objective in the formulation is to minimize the total expected social cost, including the expected cost of failure. The frequency of inspections is included as a decision variable. The probability of failure is explicitly taken into account in the c...

Structural health monitoring (SHM) provides a useful tool for ensuring safety and detecting the evolution of damage and performance deterioration of civil infrastructures. A great number of civil infrastructures under construction can be used as test beds for SHM systems. The Binzhou Yellow River Highway Bridge is a cable-stayed bridge in Shandong Province, China. An SHM system has been impleme...

Two tragic tsunamis that devastated the west coast of Sumatra Island, Indonesia in 2004 and North East Japan in 2011 had damaged bridges to various extents. Tsunamis have resulted in the catastrophic deterioration of infrastructures i.e. coastal structures, utilities and transportation facilities. A bridge structure performs vital roles to enable people to perform activities related to their da...
