Abstract:

The efficient use of public funds for the structural integrity of bridge networks requires the implementation of an effective Bridge Management System (BMS). However, for long-term planning strategies in current asset management practice, there are some fundamental shortcomings associated with the health status of bridge elements. Although extensive research have been carried out to improve the overall quality of BMS outcomes, existing deterministic and probabilistic/stochastic deterioration modelling techniques are still limited in scope and application. This is attributable to a number of re

Abstract:

Deterioration of bridge decks is an ongoing problem faced by transportation agencies across the country. In past decades, Non-Destructive Evaluation (NDE) techniques, capable of detecting various deteriorations types, e.g., cracking, delamination and reinforcing steel corrosion, have emerged. These techniques generate large amounts of data representing different underlying physics, (decibels for ground penetrating radar and volts for half-cell potential), making data interpretation and comparison difficult for bridge owners and practitioners. The deterioration threshold, or the transition betw

This dissertation presents a novel procedure to select explanatory variables, without the influence of human bias, for deterioration model development using National Bridge Inventory (NBI) data. Using NBI information, including geometric data and climate information, candidate explanatory variables can be converted into normalized numeric values and analyzed prior to the development of deterministic or stochastic deterioration models. The prevailing approach for explanatory variable selection is to use expert opinion solicited from experienced engineers. This may introduce human influenced bia

Abstract:

A probabilistic based assessment procedure for the prediction of the remaining service life of reinforced concrete bridge beams and slabs subject to reinforcement corrosion has been developed. By modelling the corrosion of reinforcement as a two stage process consisting of an initiation period and a propagation period, analytical methods have been developed and used to estimate the probability of failure with time for a number of limit states. The most common form of deterioration has been identified as the corrosion of reinforcement due to the ingress of chloride ions from de-icing salts appl

Abstract:

Bridges are vital components of any road network which demand crucial and timely decision-making for Maintenance, Repair and Rehabilitation (MR&R) activities. Bridge Management Systems (BMSs) as a Decision Support System (DSS), have been developed since the early 1990’s to assist in the management of a large bridge network. Historical condition ratings obtained from biennial bridge inspections are major resources for predicting future bridge deteriorations via BMSs. Available historical condition ratings in most bridge agencies, however, are very limited, and thus posing a major barrier for p

Abstract:

The serviceability and safety of bridges are crucial to people’s daily lives and to the national economy. Every effort should be taken to make sure that bridges function safely and properly as any damage or fault during the service life can lead to transport paralysis, catastrophic loss of property or even casualties. Nonetheless, aggressive environmental conditions, ever-increasing and changing traffic loads and aging can all contribute to bridge deterioration. With often constrained budget, it is of significance to identify bridges and bridge elements that should be given higher priority for

Infrastructure maintenance programs establish schedules for routine inspections of highway bridges with little consideration of their current conditions. The time interval between two inspections is traditionally set based on experience and on engineering judgment. For example, in the US considerable expenditures are incurred to meet the required biennial routine inspection of all bridges many of which may be in good condition. It is therefore of great interest for the engineering community to develop an approach to control inspection schedules of individual bridges and minimize their assoc

It is therefore essential that available funds are used to optimum effect for inspections, maintenance, assessment, repair or replacement.

Such bridges offer advantages of quicker construction and lower costs. However, several such bridges built in Florida developed extensive cracking and spalling.

For predicting the remaining service life of existing RC bridge in chloride-laden environments, the corrosion process has been divided into three stages, the initiation time ti, the depassivation time tp, and the corrosion time tcorr. The total service life of existing RC bridge can be expressed as t=ti+tp+tcorr. Numerous mathematical models were applied to calculate

Abstract:

碩士<br>國立臺灣科技大學<br>營建工程系<br>92<br>Corrosion of bridge structures is a problem faced by countries throughout the world. Taiwan is no different; with narrow topography metropolitan and industrial areas have been forced to intersect with coastal regions creating a complicated corrosion problem. Especially in coastal regions, bridges are directly exposed to a harsh corrosive environment creating challenges for the durability of bridge structures. This research performs an analysis and examination of the current corrosion status of bridge structures in Taiwan. A survey and analysis of
