Abstract:

As a part of Coordinated Technical Project on the Development of Repair and Strengthening Techniques for Buildings and Structures Damaged by Earthquakes, initiated in 1981 by Ministry of Constructiont Guidelines for Post-Earthquake Inspection and Evaluation of Earthquake Damage in Reinforced Concrete Buildings were developed. This paper describes the Guideline for Emergency Inspection and Evaluation for Hazard Risk of Damaged Buildings toward Aftershocks, which is intended for technical officers of a municipal government to evaluate a risk of damaged buildings immediately after earthquake hazards and to determine safe public buildings for use as places for evacuation and medical treatment. Damages of structural members, possible falling and overturning objects are to be investigated by external observation of a building.

Abstract:

This article is devoted to improving the efficiency of planning the consumption of material and technical and labor resources and their appropriate planning for heating and non-heating periods, by months of the year based on the calculation of the estimated number of damage to heating pipes, based on the obtained dependences of failure rate. This task is modern and relevant especially in conditions of limited funding of engineering systems. The object of study - the district heating system. The subject of research - pipelines of thermal networks. The purpose of the work is to determine the distribution of damage to the heating network pipelines by months. The research method is statistical modeling of damages of heating network pipelines by months of the year for different terms of their operation. Currently, the reliable operation of district heating systems and their heating networks is one of the main factors in the livelihood of settlements. The reliability of heating network pipelines is determined by the reliability indicators obtained on the basis of data on the damage of heating pipelines. Studying the distribution of the number of damages of heating network pipelines by months depending on the service life of heating pipelines is necessary for effective planning of material, technical and labor resources. In order to increase the efficiency of planning of material and technical and labor resources, it is advisable to calculate the number of damages for the heating and unheated periods, by months of the year, by decades. The calculated dependences of the distribution of damage to the pipelines of heating networks for the heating and non-heating periods on a monthly basis, decadally, should take into account the service life of the pipelines. The results of the above research will save material, technical, labor and energy resources.

Abstract:

Numerous investigations assess the technical, technological, and managerial aspects of disaster response related to large technical systems. This paper deals with the possibility of synthesizing these aspects in a disaster response methodology, thus combining the technical, technological methods, tools, and software with the art of management. Its objective is to develop a preliminary methodology that supports the response management decision making processes related to earthquake-damaged large technical systems. The introduced methodology is demonstrated with the example of railway systems. It utilizes a combination of (i) a probabilistic model of railway system damage caused by earthquakes, (ii) a Markov model related to the damage and recovery phases, (iii) a probabilistic model of aftershocks, (iv) a statistical model of secondary effects, (v) impact models of management support actions, and (vi) response process management supported by a Markov Decision Process. The simulation results validate the concept. Based on these research results, the authors recommend that the described preliminary response management approach be further specified and implemented in disaster management procedures.

Abstract:

A large number of sewage facilities were severely damaged by the Great East Japan Earthquake in March 2011, mainly by the tsunami caused by the massive earthquake. At the many sewage treatments, the systems were shut down by the tsunami, numerous building structures were toppled by the wave force of the tsunami and electrical and mechanical machines were damaged by submersion. The many pipelines damaged by liquefaction throughout the region lost their ability to carry sewage as a result of plugging by sand after the occurrence of the earthquake. In order to solve technical problems and quickly restore sewage systems, a technical review committee of experts and specialists was set up to consider ways to prevent damage to sewage systems by earthquakes and tsunami. This Committee analyzed the characteristics of the damage and made four proposals on emergency response, emergency restoration, full-scale restoration, and new policies for tsunami countermeasures.

Abstract:

In order to reduce the potential threat to the Guanyindian highway bridge caused by the damaged RC bridge pier, some damage detection methods including surface inspection, core-drilling test, ultrasonic-rebound test and verticality measurement are used to assess the bridge’s damage condition. The finite element analysis software is employed to simulate the damaged bridge pier and to calculate its bearing capacity, thus providing technical data for the repair and future maintenance of the bridge pier. According to the results of damage detection and calculation, the verticality, the concrete strength, the bearing capacity and the crack width of the damaged No.1 bridge pier could meet the code’s requirement but the damaged regions on the bridge pier need to be repaired.

Abstract:

Ces travaux de thèse portent sur la détermination des propriétés mécaniques à différentes échelles ainsi que les mécanismes d'endommagement des nitrures de silicium denses ou avec différents taux de porosités. Ces céramiques techniques présentent des propriétés mécaniques forte intéressantes : une faible densité, une dureté élevée, une bonne résistance à la corrosion et un faible coefficient de dilatation thermique. Elles sont notamment utilisées dans la fabrication des billes de roulement pour des applications dans les industries automobiles et aéronautiques. La caractérisation du comportement local sous un chargement de contact est donc un enjeu majeur. Les matériaux étudiés ont été obtenus par frittage flash d'une poudre de Nitrure de Silicium avec différents pourcentages d'oxide d'yttrium comme additif. Le contrôle de la température et de la pression de frittage a permis d'obtenir des matériaux denses avec différentes tailles de grain mais aussi avec une porosité résiduelle variable. La première partie de ce travail consistait à caractériser l'influence des conditions d'élaboration (température, pression, pourcentage d'additif) sur la microstructure (taille des grains, compositions ...) et les propriétés mécaniques à l'échelle macroscopique (module élastique, dureté Vickers, résistance à la flexion ...) des matériaux frittés. Des essais de contact de Hertz ont été ensuite réalisés afin d'identifier les mécanismes d'endommagement. L'utilisation de sphères de différents rayons a mis en évidence un important effet d'échelle : des fissures circonférentielles à échelle macroscopique (mode fragile) et des déformations plastique localisées à l'échelle mesoscopique avec des micro fissures distribuées aléatoirement (mode quasi-ductile). Les tests de nanoindentation permettent de solliciter localement les échantillons pour obtenir les propriétés élastiques des courbes force-déplacement. Des méthodes d'identification inverses permettent aussi d'extraire les paramètres d'écoulement. Le comportement non linéaire des céramiques a été modélisé en utilisant une loi bilinéaire où Sy est la limite d'élasticité et K un paramètre d'écrouissage. Afin d'identifier ces deux paramètres, un modèle éléments finis axisymétrique avec une pointe sphérique déformable a été construit sous Abaqus. Le modèle a été couplé à un module d'identification inverse fondé sur l'algorithme de Levemberg-Marquart pour minimiser l'écart (au sens des moindres carrés) entre les courbes expérimentales et numériques. Les simulations avec le code Isaac développé au sein du laboratoire LaMCoS ont permis de suivre d'évolution de la zone plastique lors d'un chargement de roulement
This work deals with the mechanical properties and damage mechanisms under contact loading of dense and porous silicon nitrides materials. These technical ceramics exhibit a very interesting combination of mechanical properties: low density, high hardness and strength, good corrosion resistance and a low thermal coefficient. They are used in many applications including ball bearings for the automotive and aerospace industries. The characterization of the local behaviour under contact loading is then a crucial issue. Spark plasma sintering technique is used to process silicon nitride ceramics with addition of different amount of yttrium oxide as sintering aid. Controlling the sintering temperature and the applied pressure has permitted to obtain materials with fine, medium and coarse microstructures. In addition, materials with different porosity contents have been obtained. First, we have investigated the influence of processing conditions (temperature, pressure, amount of yttria on the microstructure and mechanical properties at the macroscopic scale (elastic parameters, Vickers hardness, flexural resistance ...). Hertzian contact tests were then performed to identify the damage mechanisms at the surface and subsurface of the sintered materials. The use of indenting spheres of different radii permitted to observe a significant size effect. Brittle mode consisting of surface ring cracks were observed at large scale (macroscopic scale) while localized plastic deformation with microcracks randomly distributed was observed at small scale (mesoscopic scale). Transmission electron microscopy observations of thin foils machined by ion milling were performed to investigate the subsurface damage. Numerical simulations with a code developed internally in LaMCoS laboratory enabled to follow the evolution of the plastic zone under pure rolling conditions. In these simulations, the nonlinear behaviour of ceramics was modelled using a bilinear law where Sy is the yield stress and K a hardening parameter of the ceramic specimen. Instrumented indentation tests were performed using a diamond spherical tip of radius 42 µm. Experimental load versus displacement curves were used as input data for an inverse identification purpose. Levemberg-Marquart algorithm was used to minimize the gap in the least squares sense

Polders are very common hydrotechnical structures in Šilutė district. Their purpose is to protect its territories and structures from flooding. This paper examines the condition of the summer-type polder hydrotechnical structures of Alka and Smalkai, as well as the winter-type polder hydrotechnical structures of Traksėdžiai, Kintai and Ruguliai. During the research it was established that the accumulation of sediment in drainage ditches increases their bottom altitudes (the thickness of the sediment layer amounts to 0.2-1,0 m). The slopes of the dykes (in the distance of 100 metres) contains up to 10 inhabited or fallen-in rodent caves. The trench slopes and protective zones are overgrown with tall vegetation, the area of which in 100 m of the bank strip amounts to 60 m2. The damage of the reinforced mounting elements of the ditch slopes is clearly visible. The spaces between deformed, washed and shifted mounting plates are 0.5-11 cm. Slumped ground along the culverts in the carriageway resulted in deeper than 0.2-0.4 m cavities. Meeting the environmental requirements, the water level in the summer-type polder channels maintained is 0.5-1.1 m higher, compared to the operational water levels required for successful agricultural activity. The paper includes a water level monitoring data analysis and a discussion of the environmental and operational water levels in polders.

Abstract:

O objetivo da presente dissertação foi verificar os efeitos de 22 semanas de treinamento com ênfase na capacidade técnica-tática sobre o comportamento das capacidades motoras, indicadores indiretos de dano muscular [creatina quinase (CK) e lactato desidrogenase (LDH)] e o desempenho em campo de jovens futebolistas (Capítulos 2 e 3). Além disso, objetivou-se comparar o primeiro com o segundo tempo de um jogo simulado de futebol no que se refere aos padrões de deslocamento e variáveis táticas e; identificar possíveis associações entre a CK e a LDH com os padrões de deslocamento em um jogo simulado (Capítulo 4). Participaram do estudo 20 voluntários (idade 15,1 ± 0,3 anos, estatura 171,5 ± 6,1 cm, massa corporal 60,4 ± 5,5 kg, % gordura 11,5 ± 2.8, pico de velocidade de crescimento 1,42 ± 0,5 anos, VO2máx 48,68 ± 4,67 ml.kg-1.min-1). As capacidades motoras foram acompanhadas por meio dos testes motores: salto vertical e salto horizontal; T-40; Shuttle Run Test e o Running Anaerobic Sprint Test. Para determinação da atividade plasmática das enzimas CK e LDH foram realizadas coletas de sangue venoso (10ml). O desempenho em campo foi verificado por meio de análises cinemáticas bidimensionais dos padrões de deslocamento (distância total, velocidade média, número de sprints, % nas zonas de intensidade) e variáveis táticas (área de ocupação da equipe, espalhamento dos jogadores) em um jogo simulado filmado por duas câmeras captando toda a área do jogo. O desempenho nas partidas da competição alvo foi analisado por meio do aproveitamento de pontos. Todas as avaliações supracitadas foram realizadas em quatro momentos distintos: pré etapa preparatória (T0); pós etapa preparatória (T1); pós etapa competitiva I (T2); pós etapa competitiva II (T3). Para todos os resultados obtidos por meio dos testes motores foram encontradas diferenças significantes (p 0,05) quando comparado os momentos T0 (pré-treinamento) com T3 (pós-treinamento), no sentido de ganho/melhora (Capítulo 2). No desempenho das partidas foi verificado um aproveitamento de 83,33% nos pontos disputados (Capítulo 2). Em relação ao comportamento dos padrões de deslocamento e variáveis táticas ao longo da periodização, foi verificado aumento significante (p 0,05) da intensidade do jogo e do desempenho tático quando comparado o momento T0 com T3. Fato evidenciado devido o aumento das variáveis: porcentagem da distância total percorrida em sprinting, em alta intensidade (AAI), na velocidade máxima, área de ocupação e espalhamento (Capítulo 3). No que refere-se à atividade plasmática da CK e da LDH, observou-se uma redução significante (p 0,05) (Capítulo 3). Em relação ao Capítulo 4, observa-se nos resultados um aumento significante (p 0,05) da distância total, da velocidade média, do número de sprints, AAI e das variáveis táticas no segundo tempo do jogo simulado. Em adição, verificou-se diminuição significante da porcentagem da distância total percorrida em baixa intensidade no segundo tempo. Além disso, verificou-se grande associação entre a porcentagem do delta de alteração da CK e da LDH com os padrões de deslocamento no jogo simulado. Conclui-se no Capítulo 2 um aprimoramento significativo nos índices das capacidades motoras dos futebolistas estudados, além de um expressivo aproveitamento de pontos na competição alvo. No Capítulo 3 sintetiza-se que houve aumento do desempenho em alta intensidade no jogo, no rendimento tático e redução da atividade dos marcadores bioquímicos relacionados ao dano muscular. Em relação ao Capítulo 4 conclui-se que indicadores indiretos de dano muscular possuem grande associação com padrões de deslocamento em jogo realizado em condições de treino por jovens futebolistas
The purpose of the present dissertation was to verify the effects of 22 weeks of training, emphasizing the technical-tactical ability, on the behavior of motor capacities, indirect skeletal muscle damage markers [creatine kinase (CK) and lactate dehydrogenase (LDH)] and field performance of young soccer players (Chapters 2 and 3). Furthermore, it was aimed to compare the first and second halves of a simulated match regarding displacement patterns and tactical variables; and identify potential associations between the CK and LDH with the displacement patterns within the simulated match (Chapter 4). Twenty volunteers accepted to participate in this study (age 15.1 ± 0.3 years; height 171.5 ± 6.1 cm; body weight 60.4 ± 5.5 kg; body fat % 11.5 ± 2.8; peak height velocity 1.42 ± 0.5 years; VO2max 48.68 ± 4.67 ml.kg-1.min-1). The motor capacities were assessed by the motor tests: vertical jump and horizontal hump; adapted T-40; Shuttle Run Test and Running Anaerobic Sprint Test (RAST). To determine CK and LDH plasmatic activity, vein blood samples were collected (10ml). The field performance was assessed by displacement patterns kinematic two-dimensional analysis (total distance; average velocity; number of sprints; % on each intensity zone) e tactical variables (team occupation zone; players field distribution) on a simulated match, recorded by two cameras covering the whole area of the match. The performance on matches within the target competition were analyzed by earned points during the period. All the assessments mentioned were performed in four distinct moments: before preparatory stage (T0); after preparatory stage (T1); after competitive stage I (T2); and after competitive stage II (T3). When comparing moments T0 (before training program) and T3 (after training program), significant differences were found for all results regarding motor tests (p 0.05), in the direction of gain/improvement (Chapter 2). On matches performance, 83.33% of the contested points were achieved (Chapter 2). Regarding the behavior of the displacement patterns and tactical variables over the periodization, it was verified a significant improvement (p 0.05) on games intensity and tactic performance when comparing moments T0 and T3. This fact is proved by an increase of the variables: percentage of sprinting total covered distance, in high intensity, in maximal intensity, occupation and field distribution (Chapter 3). Concerning the plasmatic activity of CK and LDH, it was observed a significant reduction (p 0.05) (Chapter 3). On the Chapter 4, it is noticed on the results an significant improving (p 0.05) of total distance, average velocity, number of sprints, high intensity activities and tactical variables. Additionally, it is possible to verify a significant decreasing of low intensity total distance covered percentage on the second half. Moreover, it can be observed a large association between the percentage of CK and LDH delta variation with the displacement patterns on the simulated match. Through the Chapter 2 evidences, it is possible to conclude a significant enhancement of the motor capacities rates of the studied soccer players, besides an expressive earned points on the target competition. On Chapter 3 it is evident the performance gains during high intensity efforts along the match, on tactical performance and the reduction on biochemical markers for skeletal muscle damage. Yet, by the Chapter 4 outcomes, it is allowed to conclude that indirect skeletal muscle damage markers have large association with displacement patterns during a match performed on training conditions by young soccer players

Abstract:

Background: Although the negative impact of sleep apnea on the clinical course of acute ischemic stroke (AIS) is well known, data regarding non-invasive ventilation in acute patients are scarce. Several studies have shown its tolerability and safety, yet no controlled randomized sequential phase studies exist that aim to establish the efficacy of early non-invasive ventilation in AIS patients. Methods/design: We decided to examine our hypothesis that early non-invasive ventilation with auto-titrating bilevel positive airway pressure (auto-BPAP) positively affects short-term clinical outcomes in AIS patients. We perform a multicenter, prospective, randomized, controlled, third rater- blinded, parallel-group trial. Patients with AIS with proximal arterial obstruction and clinically suspected sleep apnea will be randomized to standard stroke care alone or standard stroke care plus auto-BPAP. Auto-BPAP will be initiated within 24 hours of stroke onset and performed for a maximum of 48 hours during diurnal and nocturnal sleep. Patients will undergo unattended cardiorespiratory polygraphy between days three and five to assess sleep apnea. Our primary endpoint will be any early neurological improvement on the NIHSS at 72 hours from randomization. Safety, tolerability, short-term and three-months functional outcomes will be assessed as secondary endpoints by un-blinded and blinded observers respectively. Discussion: We expect that this study will advance our understanding of how early treatment with non-invasive ventilation can counterbalance, or possibly reverse, the deleterious effects of sleep apnea in the acute phase of ischemic stroke. The study will provide preliminary data to power a subsequent phase III study.

Abstract:

Background: Although the negative impact of sleep apnea on the clinical course of acute ischemic stroke (AIS) is well known, data regarding non-invasive ventilation in acute patients are scarce. Several studies have shown its tolerability and safety, yet no controlled randomized sequential phase studies exist that aim to establish the efficacy of early non-invasive ventilation in AIS patients. Methods/design: We decided to examine our hypothesis that early non-invasive ventilation with auto-titrating bilevel positive airway pressure (auto-BPAP) positively affects short-term clinical outcomes in AIS patients. We perform a multicenter, prospective, randomized, controlled, third rater- blinded, parallel-group trial. Patients with AIS with proximal arterial obstruction and clinically suspected sleep apnea will be randomized to standard stroke care alone or standard stroke care plus auto-BPAP. Auto-BPAP will be initiated within 24 hours of stroke onset and performed for a maximum of 48 hours during diurnal and nocturnal sleep. Patients will undergo unattended cardiorespiratory polygraphy between days three and five to assess sleep apnea. Our primary endpoint will be any early neurological improvement on the NIHSS at 72 hours from randomization. Safety, tolerability, short-term and three-months functional outcomes will be assessed as secondary endpoints by un-blinded and blinded observers respectively. Discussion: We expect that this study will advance our understanding of how early treatment with non-invasive ventilation can counterbalance, or possibly reverse, the deleterious effects of sleep apnea in the acute phase of ischemic stroke. The study will provide preliminary data to power a subsequent phase III study.

Abstract:

AbstractThis chapter provides an overview of the common types of defects found in various structural materials and joints in aircraft. Materials manufacturing methods (including large-scale production) have been established in the aircraft industry. However, as will be seen in this chapter, manufacturing defects and defects during in-service conditions are very common across all material types. The structural material types include metals, composites, coatings, adhesively bonded and stir-welded joints. This chapter describes the defect types as a baseline for the description of their detection with the methods of Chap. 10.1007/978-3-030-72192-3_5 to 10.1007/978-3-030-72192-3_8. Based on the understanding of the defect types, there is great expectation for a technical breakthrough for the application of structural health monitoring (SHM) damage detection systems, where continuous monitoring and assessment with high throughput and yield will produce the desired structural integrity.

Abstract:

<p>Strong seismic shaking is recognized as the direct cause of structural failures. In many cases, however, the factor that initiates the structural damage is ground failure or ground displacement. This chapter deals with the identiﬁcation of all geotechnical related structural failures. Surface fault rupture has been a well-acknowledged cause of failures of structures built across or near the fault, which are increasing in frequency as the man-made environment constantly expands to new areas. Seismically induced rockfalls, landslides and slope failures have also been associ-ated with major disasters with an increasing frequency in some cases due to an expanding popu-lation, which encroach on areas with landslide risk or in other cases as result of the destruction of the natural environment (vegetation and water routes), which have protected these slopes in the past. Foundation damage may be a result of failure of shallow foundations or piles. In addition, although liquefaction and ground settlement are technically part of foundation failures, they are usually treated as separate, special cases. Retaining wall structures, usually considered as simple systems, may display a complex behaviour, which can be related to extensive seismic failures. Finally, not taking into account soil–structure interaction (SSI) may have a detrimental effect on the dynamic response of structures. Although SSI may never be the direct cause of a structural failure, it has proven to be, in several cases, the underlying reason for the analysis misconception that led to the failure.</p>

Abstract:

Abstract When a damage exists in a structure, the dynamic characteristics of the structure are changed. A great deal of effort has been elaborated to determine the position and the amount of the damage by using the natural frequencies and the mode shapes. In this paper, a theoretical method is given to detect the damage in a structure based on the changes of its natural frequencies and the mode shapes. After determining the location of the damage, a correcting factor describing a reduction in stiffness of damaged element gives the amount of the damage. This method is proved on two examples of beam structures.

Abstract:

Drives to improve gas turbines efficiency have lead to an increase in firing temperatures. This increase in exhaust temperature has a negative impact upon turbine blade life. Both engineers and material scientists have produced methods to improve turbine blade life under these conditions. Cooling holes have become commonplace and use relatively cool gas to create a lower temperature barrier around a turbine blade. These cooling holes creating internal and external surfaces; a common sight of crack initiation. Directionally-solidified (DS) turbine blades have also become commonplace. These turbine blades exhibit a transversely-isotropic grain structure that improves creep strength in a desired direction. To model a component under such conditions, anisotropic constitutive models are required. In this paper, an anisotropic tertiary creep damage constitutive model for transversely-isotropic materials is given. The influence of creep-damage on general linear elasticity (elastic damage) is described by a modified Hooke’s compliance tensor. Finite element simulations of a V-notched tensile specimen are conducted to replicate a crack initiation site. A discussion on stress triaxiality, stress redistribution, and damage distribution due to anisotropy is provided.
