Abstract:
The importance of facility management (FM) has gradually been recognized in the life cycle of a building. Both new and existing buildings require a more efficient approach and advanced technology to improve the efficiency of the FM. The study is aimed to enhance the facility repair process. Thus, the study presents a building information modeling (BIM)-based facility repair platform framework, which enables expedited reporting for repairs and a comprehensive listing of the status, location, and maintenance record facilities. To effectively facilitate the FM information transfer among stakeholders, firstly, the study presents a facility traceability coding structure for building facilities, the proposed platform framework. The proposed facility traceability information coding in QR code format can help general users and FM personnel identify and locate the specific or abnormal facility quickly. Secondly, the study demonstrates that how to apply the proposed code in QR code format in the BIM-based facility repair platform with a case test. The research findings showed that the proposed method enables FM personnel to significantly improve the efficiency of FM, which can help FM personnel make preliminary facility repair judgments and schedule maintenance plan to track the status of the facility repair which can help improve the efficiency of facility management and simplify the repair process.

Abstract:
Identification of non-structural damage in concrete infrastructure and actuation of preventive repair solutions is an established approach to avoid further structural damages and more expensive repair regimes. However the repair of concrete itself is not infallible with 55% of reported repairs in the EU failing within 5 years of service. Thus the already once repaired concrete structure is then subject to a constant cycle of repeated repair and a cumulative associated life cycle cost. The development of external repair material with self-healing capabilities, can affect a real step-change on the life-cycle costs and maintenance of existing and new infrastructure. Developed polymeric microcapsules containing liquid sodium silicate were used to impart autonomic self-healing to readily available commercial repair mortars for the first time. These materials cover a range of potential real time repair applications. Initially the compatibility between the developed self-healing agents and commercial products was established and the self-healing performance of the novel composite system was then evaluated. The results underlined the huge potential for the proposed composite systems as a stepping stone toward commercial uptake of self-healing microcapsule-based cementititious materials.

Abstract:
This paper proposes a design methodology for self-maintenance machines. The self-maintenance machine is a machine that can maintain its functions for a while, even though faults happen. In order to achieve capabilities for diagnosing and repair planning, a model based approach that employs qualitative physics is proposed. Regarding repair execution, two types of repair strategies are proposed; viz., control type and functional redundancy type which is a strategy to add redundancy to a machine from a viewpoint of function. A prototype of the self-maintenance machine is developed. Because this machine uses the control type of repair strategy, it succeeded to maintain its functions as far as its structure does not change. A promising candidate for dealing with faults that involve structural changes is the functional redundancy type of repair.

Abstract:
Heat-straightening repair of damaged steel girders has been conducted on a number of bridges over the years. However, little documentation is available on repair methodology and response to such repairs. Such documentation for the field repair of a bridge in Iowa is provided. The Iowa Department of Transportation (IDOT) decided to train its maintenance personnel to perform heat-straightening repairs. The training program consisted of 2 days of classroom and laboratory tutorial training and a field heat-straightening project. The field project was a bridge spanning I-80 near Davenport. The repair was successfully completed and demonstrated the practicality of implementing recent advances in heat-straightening research. The response of the damaged girder to the heat-straightening process was also measured and compared with theoretical models.

Abstract:
Production lines are usually subjected to emergent machine failures. Such emergent failures disrupt pre-established maintenance schedules, which challenge maintenance engineers to react to those failures in real time. This research proposes an optimization procedure for optimizing scheduling repairs of emergent failures. Three optimization models are developed. Model I schedules failures in newly idle repair shops with the objective of maximizing the number of scheduled repairs. Model II maximizes the number of assigned repairs to untapped ranges. Model III maximizes both the number of assigned failure repairs and satisfaction on regular and emergency repairs by resequencing regular and emergent failures in the shop that contains the largest free margin. A real case study is provided to illustrate the proposed optimization procedure. Results reveal that the proposed models efficiently scheduled and sequenced emergent failures in the idle maintenance shops, the untapped ranges between repairs of regular failures, and in the maintenance shop with the largest free margin. In conclusions, the proposed models can greatly support maintenance engineers in planning repairs under unexpected failures.

Abstract:
The AP-3C Orion aircraft is the oldest aircraft in the Royal Australian Air Force (RAAF) inventory. The planned fleet withdrawal has been extended far beyond the original design service objective. Continued safe and effective operation has required the development of a robust ageing aircraft management approach. A fundamental aspect was supplementing the structural certification basis with appropriate standards in the form of fatigue management requirements from Federal Aviation Regulations (FAR) 25.571 and Federal Aviation Administration Advisory Circular (FAA AC) 120-93. To develop and underpin the ageing aircraft management plan and transition to the supplementary fatigue management standards, the RAAF collaborated with the Original Equipment Manufacturer, Lockheed Martin Aeronautics Company, the United States Navy (USN) and other operators to form the P-3C Service Life Assessment Program (SLAP). This program provided Full Scale Fatigue Test (FSFT) data, associated analyses and analysis tools to support management in accordance with FAR 25.571. An important element of the ageing aircraft management plan included the introduction of a rigorous Safety By Inspection (SBI) maintenance regime to assure structural airworthiness. FAA AC 120-93 requires assessment of structural repairs to determine revised fatigue management and inspection requirements. Often, this information is derived using tailored analysis tools and detailed models on a case-by-case basis. This approach is specialized, expensive and usually occurs after the repair has been designed and installed. To avoid these limitations, the AP-3C Repair Assessment Manual (RAM) was developed to provide the repair designer with a design handbook approach to fatigue analysis. In conjunction with some simple Finite Element (FE) models, the RAM supports complete repair analysis prior to an aircraft leaving the maintenance venue. This paper will present the history of the SBI program, the genesis of the RAM and actual examples of assessing structural repairs on the P-3 platform using the RAM.

Abstract:
The authors' company is a medium-sized engineering company specializing in naval ship repair. The bulk of corporate work centers on the Phased Maintenance (PM) of three classes of ships. Typically, each PM contract covers three to five different ships per class scheduled for 90-day Availabilities at approximately one-year intervals over a period of five years. The type of work to be performed during each Phased Maintenance Availability (PMA) falls into one of two categories: ship alterations or ship repairs. The first group, ship alterations, is characterized by detailed, long-lead engineering and planning efforts, typically beginning 540 days prior to the vessels's arrival. The second group, ship repairs, makes up the other end of the spectrum with short lead times and compressed service details. The majority of repair items are identified 60 days prior to an Availability, while some are not determined until after the vessel has arrived in the shipyard. The engineering department that services PMA work is composed of three disciplines: structural, mechanical and electrical. The mechanical discipline is further subdivided into the areas of machinery and piping/HVAC. While the nature of PMA work within each discipline is peculiar to the application, the process is similar in each. Reference information is gathered and verified, technical analysis is provided where necessary, and detailed drawings are prepared and submitted for Navy approval prior to shipyard production. All drawings are developed using two-dimensional drafting techniques at various sites by teams of computer-aided design (CAD) input operators utilizing color graphic workstations on a multi-shift basis as required by the workload. Completed drawings are transferred to the engineering site over a network link, where additional workstations are available for engineers to check and correct them as necessary

Abstract:
Rational decisions about cost-effective maintenance and structural repair are hampered by the absence of comprehensive data on structural performance of generic repair materials acting compositely with deteriorated concrete elements. In the present climate of durability problems in concrete construction such information is of critical importance. In order to assess long-term structural performance of repaired elements, basic short and long-term properties of generic repair materials are required under various exposure conditions. The principle requirements to ensure satisfactory long-term performance of the repair have always been high dimensional stability and relatively high early bond strength of the repair material with the substrate concrete. As part of a "Brite Euram" project, sponsored by E.E.C., the author has obtained considerable experimental data on properties of three commercially available generic repair materials, which are significant to the subsequent structural behaviour of repaired concrete members. A comparison is also made between the performance of these repair materials with a plain concrete mix of similar strength and stiffness. The following generic repair materials were used: a high performance non-shrinkable concrete, a mineral based cementitious material with no additives and no coarse aggregate size particles, and a cementitious mortar which contains styrene acrylic copolymer with fibre additives. The repair materials are supplied as single component systems by their manufacturers, ready for on-site mixing and use, and require only the addition of clean water. Data on strength, stiffness, post peak-load ductility under compression, swelling, shrinkage and creep deformations under various curing conditions are presented in this thesis. In addition water permeability coefficients and chloride penetration profiles of the materials at various ages of exposure have been determined. A comprehensive compilation of chloride diffusion data is made and an empirical expression is derived for the prediction of long-term chloride penetration profiles based on data obtained at relatively early ages. Application of this prediction model to the field data of some Arabian Gulf structures is made. The influence of repair materials on the performance of reinforced concrete compression members has been studied. A theoretical model is also derived to predict the long-term structural interaction between a repair patch and substrate concrete in short compression members of reinforced concrete. The model is based on the basic properties of materials, such as creep deformation, drying shrinkage and modulus of elasticity. The validity of the model is established on the basis of the experimental data obtained in this study. At the end of the thesis, conclusions and recommendations for future research are made.

Abstract:
Information Technology (IT) can exploit strategic opportunities for new ways of facilitating information and data exchange and the exchange of expert and specialist opinions in any field of engineering. Knowledge-Based Systems are sophisticated computer programs which store expert knowledge on specific subject and are applied to a broad range of engineering problems. Integrated Database applications have facilitated the essential capability of storing data to overcome an increasing information malaise. Integrating these areas of Information Technology (IT) can be used to bring a group of experts in any field of engineering closer together by allowing them to communicate and exchange information and opinions. The central feature of this research study is the integration of these hitherto separate areas of Information Technology (IT). In this thesis an adaptable Graphic User Interface Centred application comprising a Knowledge-Based Expert System (DEMARECEXPERT), a Database Management System (REPCON) and Evaluation program (ECON) alongside visualisation technologies is developed to produce an innovative platform which will facilitate and encourage the development of knowledge in concrete repair. Diagnosis, Evaluation, MAintenance and REpair of Concrete structures (DEMAREC) is a flexible application which can be used in four modes of Education, Diagnostic, Evaluation and Evolution. In the educational mode an inexperienced user can develop a better understanding of the repair of concrete technology by navigating through a database of textual and pictorial data. In the diagnostic mode, pictures and descriptive information taken from the database and performance of the expert system (DEMAREC-EXPERT) are used in a way that makes problem solving and decision making easier. The DEMAREC-EXPERT system is coupled to the REPCON (as an independent database) in order to provide the user with recommendations related to the best course required for maintenance and in the selection of materials and methods for the repair of concrete. In the evaluation mode the conditions observed are described in unambiguous terms that can be used by the user to be able to take engineering and management actions for the repair and maintenance of the structure. In the evolution mode of the application, the nature of distress, repair and maintenance of concrete structures within the extent of the database management system has been assessedT. he new methodology of data/usere valuation could have wider implications in many knowledge rich areas of expertise. The benefit of using REPCON lies in the enhanced levels of confidence which can be attributed to the data and to contribution of that data. Effectively, REPCON is designed to model a true evolution of a field of expertise but allows that expertise to move on in faster and more structured manner. This research has wider implications than within the realm of concrete repair. The methodology described in this thesis is developed to provide tecýnology transfer of information from experts, specialists to other practitioners and vice versa and it provides a common forum for communication and exchange information between them. Indeed, one of the strengths of the system is the way in which it allows the promotion and relegation of knowledge according to the opinion of users of different levels of ability from expert to novice. It creates a flexible environment in which an inexperienced user can develop his knowledge in maintenance and concrete repair structures. It is explained how an expert and a specialist can contribute his experience and knowledge towards improving and evolving the problem solving capability of the application.

Abstract:
Genomic stability refers to an organism’s ability to maintain and pass forward its genetic information. There are a raft of proteins and pathways whose sole purpose is maintaining this stability through swiftly replicating DNA as well as accurately repairing damage caused through contact with endogenous and exogenous DNA damaging elements. This study will focus on the structural aspects of two proteins that play a part in different areas of genome maintenance. Flap Endonuclease 1 (FEN 1) works in DNA replication, where it is tasked with removing a small RNA flap that is created during Okazaki fragment formation. This flap removal is essential to mature these fragments into one continuous strand of nascent DNA. Using the archeon Pyrococcus abyssi (Pab) as a model system has the advantage of possessing simple replicative machinery, whilst bearing striking similarities with the human system. Pab is a hyperthermophilic, piezophile meaning it thrives in conditions of high temperature and pressure. DNA-dependent protein kinase (DNA-PK) is a holoenzyme that plays a role in the Non Homologous End Joining (NHEJ) pathway by repairing DNA double strand breaks (DSB’s). In cancer therapy, a patient is exposed to DNA damaging elements, leading to an ever-increasing population of DSBs. If an inhibitor of DNA-PKcs were introduced along with this therapy it could potentiate its effect, as the cancerous cells will be less able to repair the damage. The aim of this part of the study is to determine a protocol to generate pure, soluble, correctly folded protein for the purposes of biophysical characterisation and X-ray crystallographic structural studies.

Abstract:
A Damage Assessment Model, Construction Process Model and Parametric Quantity Model were developed with the purpose of capturing the engineering knowledge involved in the estimating process of bridge repair construction projects. The Damage Assessment Model was used to create a sample database in which detailed inspection data was stored in a format compatible with the existing Pontis?tabase. Detailed inspection data, which provided quantitative values for the different damage types observed in bridges, could be retrieved from the sample database so that data could be used as either input parameters in the knowledge rules that triggered the selection of construction tasks in the Construction Process Model, or data could be used as variables in the equations used to estimate quantities in the Parametric Quantity Model. The Construction Process Model was used to incorporate the logic behind the construction process for different repair methods. The Construction Process Model was composed of seven repair matrices that defined specific repair methods for each Pontis?idge element. Construction tasks were grouped in construction modules that were modeled as flowcharts. Each construction module flowchart was composed of construction tasks arranged in sequential order and decision points that triggered the selection of construction tasks based on input parameters and knowledge rules. Input parameters were provided by the user, retrieved from the model or pre-defined in the model by expert knowledge. The construction modules developed involved construction tasks related to the repair of concrete bridge piles that were damaged due to reinforcement corrosion and related concrete deterioration. Data describing the construction tasks that were considered in the construction module flowcharts were modeled using the entity-relationship model and were stored in the sample database described previously. The Parametric Quantity Model combined data generated by the Damage Assessment Model and the Construction Process Model with additional expert knowledge and parameters into equations that were used to estimate quantities. The author investigated the use of neural networks as a tool to predict actual damage in bridge piles, conducted a preliminary survey to define labor productivity factors and collected data to define the duration of construction activities related to bridge repair.

Abstract:
Este trabalho apresenta o desenvolvimento de sistemas inteligentes aplicados ao monitoramento de estruturas aeronáuticas abordando dois modelos distintos: o primeiro é a análise e classificação de imagens de ultrassom de estruturas aeronáuticas com objetivo de apoiar decisões em reparo de estruturas aeronáuticas. Foi definido como escopo do trabalho uma seção transversal da asa da aeronave modelo Boeing 707. Após a remoção de material superficial em áreas comprometidas por corrosão, é realizada a medição da espessura ao longo da área da peça. Com base nestas medições, a Engenharia realiza a análise estrutural, observando os limites determinados pelo manual de manutenção e determina a necessidade ou não de reparo. O segundo modelo compreende o método de impedância eletromecânica. É proposto o desenvolvimento de um sistema de monitoramento de baixo custo aplicado em uma barra de alumínio aeronáutico com 10 posições de fixação de porcas e parafusos. O objetivo do sistema é avaliar, a partir das curvas de impedância extraídas do transdutor PZT fixado na barra, sua capacidade de classificar a existência ou não de um dano na estrutura e, em caso de existência do dano, indicar sua localização e seu grau de severidade. Foram utilizados os seguintes classificadores neste trabalho: máquina de vetor de suporte, redes neurais artificiais e K vizinhos mais próximos.
This work presents the development of intelligent systems applied to the monitoring of aircraft structures addressing two distinct models: the first is the analysis and classification of ultrasound images of aircraft structures in order to support decisions on repair of aircraft structures. A scope of work was defined as a cross section of the wing of the aircraft model Boeing 707. After the removal of surface material in damaged areas by corrosion, thickness measurements in the whole structure are evaluated. Based on the measurements, the Engineering performs structural analysis, observing the limits determined by the maintenance manual and determining the necessity of repair. The second model includes the method of electromechanical impedance. It is proposed to develop a low cost monitoring system applied to an aircraft aluminum bar with 10 positions for fixing nuts and bolts. The goal of the system is to classify an impedance curve in the condition of the aluminum bar if there is or not a damage to the structure and, in case of the existence of damage, indicating their position in the aluminum bar and if the damage is severe or not. The following classifiers were used in this work: support vector machine, artificial neural networks and K nearest neighbors.

Abstract:
This thesis examines the stress relaxation phenomenon that may occur in stainless steel rods that are used as part of an all-stainless steel externally post-tensioned rod system for strengthening reinforced concrete pier caps in shear. An overview of the stress relaxation phenomenon and its modeling is presented. Previous work on stress relaxation of stainless steel is reviewed and used to select an appropriate stress relaxation model to analyze the stress relaxation data obtained from experiments performed during this research. An experimental program utilizing six specimens of Type 304/304L stainless steel stainless steel rods similar to those likely to be candidates for pier cap rehabilitation is presented, and the data are analyzed using the model identified from the review. This model reasonably captures the behavior of the resulting stress relaxation with time, and calculates stress values that are fairly close to those obtained experimentally. Using this model to predict long-term stress losses in a service environment, guidelines for design and installation of the post-tensioned stainless steel rods are proposed.

Abstract:
<p>How should bridges be considered with regard to sustainability? Should it be by maximizing the use of recycled materials and minimizing CO2 emissions and the use of water? Alternatively, should it be by taking its impacts on local communities during their planning and execution into account? Or, might it be by designing bridges to minimize the need for maintenance and repair during their intended service lives? None of these approaches is necessarily right or wrong, but none on its own suffi ciently addresses the breadth and complexity of the challenge posed by sustainability and sustainable thinking to all those involved with bridges—as owners, designers, constructors, maintainers, and users.</p>

Abstract:
This paper studies the optimal plan for inspection and maintenance of steel structural components in tension by uniform corrosion, considering the following: A deteriorating model uncertain in time is considered, the probability to detect damage during the inspections is modeled, if damage is detected, the structural component is repaired, the failure probability of the component over time is considered supposing that the demands and capacities are random in time, the optimal plan will be the one in which the expected costs (costs of inspection, repair and failure) are minimum in the life cycle of the component, allowing to detect the number of inspections that minimize the expected costs; to determine the optimal plan, all the possibilities that are given of the tree diagram are studied, where each inspection has two existent possibilities: repair or not to repair, the occurrence possibility of each branch in the resulting tree diagram is calculated. In addition, the influence of the variables and parameters are calculated as: the net discount rate of money (r), uniform corrosion rate (ν), the mean load (μS), failure costs (Cf), repair cost (Crep) inspection cost (Cins) and quality of a nondestructive inspection (η0.5). The results indicate that the optimal number of inspections in the life-cycle of the component is sensible to each of the parameters involved, therefore every value of the variables that intervene in an optimization study must be fully justified.

Abstract:
Abstract This paper proposes a design methodology for a self-maintenance machine. The self-maintenance machine is a machine that can maintain its functions for a while, even though faults happen. In order to achieve functions for diagnosing and repair planning, a model based approach that employs qualitative physics is proposed. Regarding repair executing function, two types of repair strategies are proposed; viz., control type and functional redundancy type which is a strategy to add redundancy to a machine from a viewpoint of function. A prototype of the self-maintenance machine is developed. Because this machine uses the control type of repair strategy, it succeeded to maintain its functions as far as its structure does not change. A promising candidate for dealing with faults that involve structural changes is the functional redundancy type of repair.

Abstract:
Deterioration of components and structures at power generating facilities has caused unscheduled plant outages, personnel safety concerns, and significant impact on operating budgets. However, new technology is now available that can increase the usable life of components and structures, while significantly reducing the economic burden normally associated with repair or replacement options. This technology, known as “Fiber Reinforced Polymers” or FRP, primarily utilizes carbon fibers and high strength epoxy resins to restore or enhance the structural and or pressure boundary capacity of plant components. The extent of the FRP reinforcement is determined by the targeted equipment operating parameters, and the inter-action of the composite materials with the host component. These repairs are typically accomplished in-place with small crews and completed during a relatively short duration. The material technology and engineering associated with FRP repair methods provides an effective mechanism to rehabilitate piping, pumps, heat exchangers, water boxes, structural shapes and numerous other items while minimizing the cost typically associated with direct replacement. This paper will focus on typical applications, design and installation of FRP technology as it relates to maintenance activities at power generating facilities.

Abstract:
Remedial repairs were carried out on a railway bridge with severe corrosion damage to its steelwork as part of a project to open the passage of freight trains to a railway line in the Upper Silesia region in southern Poland. The bridge was constructed in 1907, using rimmed mild steel for the riveted plate girder superstructures . While the bridge retrofitting plan was being drawn up, the chemical composition of its structural steel members was assessed, and the ste el'' s weldability was confirmed via tensile tests and carbon equivalents. The existing steelwork was strengthened by restoring section losses in the main girders and end cross beams. The stnuctural integrity of the badly-corroded steelwork was recovered, allowing the return of both freight and passenger trains to the railway line.

Abstract:
Static structural engine components are typically designed for full lifetime operation. Efforts to reduce weight in order to improve performance result in structural designs associated with higher lifing uncertainty: Maintaining reliability levels may necessitate expensive manufacturing and maintenance solutions. In practice, repair techniques for such structures are available; however, they are not planned for during the design process. The objective of the research presented in this paper is to model and optimize component lifecycle costs with respect to lifing decisions, demonstrated by means of an aeroengine component design example. Both technical (failure) and legislative (certification) implications are considered. The impact of maintenance strategies (repair and/or replace) on lifing design decisions is quantified. It is shown that, under different conditions, it may not be prudent to design for full life but rather accept shorter life and then repair or replace the component. This is especially evident if volumetric effects on low cycle fatigue life are taken into account. It is possible that failure rates based on legacy engines do not translate necessarily to weight-optimized components. Such an analysis can play a significant supporting role in engine component design in a product-service system context.

Abstract:
The integrity of pipelines transporting hydrocarbon is critical to economy, safety and environment. One of the leading cause of pipeline failures is 3rd party damage during excavation activities, followed by corrosion, which is becoming increasingly significant as the pipeline infrastructure ages. Current inspection techniques for corrosion monitoring may require the pipeline to be shutdown during inspection reducing overall availability and a potential loss of revenue. Structural Health Monitoring (SHM) offers the promise of a paradigm shift from schedule-driven maintenance to condition-based maintenance (CBM) of pipeline structures. Built-in sensor networks integrated with the pipeline can provide crucial information regarding the condition and damage state of the structure. Diagnostic information from sensor data can be used for prognosis of the health of the structure and facilitate informed decision processes with respect to inspection and repair, e.g., repair vs. no repair or replacement. Asset management can be performed based on the actual health and usage of structures, thereby minimizing in-service failures and maintenance costs, while maximizing reliability and readiness. This paper provides an overview on the design of a SHM system for in-situ real-time, rapid assessment of pipeline integrity using a built-in sensor network. Results of a cost-benefit study conducted for the system usage on pipeline structures will also be presented.

Abstract:
The U.S. Army Corps of Engineers (USACE) currently operates and maintains approximately 193 commercially active lock sites with 239 locks and dams spanning nearly 12,000 miles. These networks of water channels are used to transport 600 million tons of domestic cargo, generating $405 billion in revenue annually. Nearly 60% of these structures in operation are over 50 years old and have reached design life. A failure of the miter gates could result in a major negative impact on the economy and on the ability to maintain flood control. Administrators need recommendations to better prioritize maintenance and repair of the USACE miter gates. This work investigated the influence of miter gate’s quoin block degradation on load transfer to the pintle and/or pintle connections. Results of finite element analysis are reported for the quoin block degradation simulated levels of 0%, 25%, 50%, and 75%. The parametric study shows the overstressed regions are the pintle neck and bolt-hole regions. To improve pintle designs so they may better mitigate detrimental environmental based deterioration effects, this work recommends (1) increasing the thickness of the bolt-hole connection region and (2) adding ribbing reinforcement around the neck area of the pintle.
