Structural Health Monitoring and Assessment: Sensors and Analysis

Structural health monitoring SHM involves the observation and analysis of a system over time using periodically sampled response measurements to monitor changes to the material and geometric properties of engineering structures such as bridges and buildings. For long term SHM, the output of this process is periodically updated information regarding the ability of the structure to perform its intended function in light of the inevitable aging and degradation resulting from operational environments. After extreme events, such as earthquakes or blast loading, SHM is used for rapid condition screening and aims to provide, in near real time, reliable information regarding the integrity of the structure. Measurements may be taken to either directly detect any degradation or damage that may occur to a system or indirectly by measuring the size and frequency of loads experienced to allow the state of the system to be predicted. To directly monitor the state of a system it is necessary to identify features in the acquired data that allows one to distinguish between the undamaged and damaged structure. One of the most common feature extraction methods is based on correlating measured system response quantities , such a vibration amplitude or frequency, with observations of the degraded system. Damage accumulation testing, during which significant structural components of the system under study are degraded by subjecting them to realistic loading conditions, can also be used to identify appropriate features.

Mosbeh R. Structural health monitoring SHM aims to assess the behavior of structures and evaluate the performance of materials during the life cycle of the structures. Such assessment should include the different parts of the structure and full assembly of the structure as a whole under different cases of loadings. SHM involves the integration of sensors, smart materials, data transmission, computational power, and processing inside the structure.

ASME-Wiley, This chapter describes a wide range of experiments conducted in both controlled laboratory and challenging field environments to evaluate the performance of the computer vision sensor system for measuring dynamic displacement. Laboratory shaking table tests are carried out to compare the accuracy of displacements measured by vision sensors that track high-contrast artificial targets and low-contrast natural targets, respectively, on the structural surface as well as by reference sensors. The robustness of the vision sensor is examined in unfavorable environmental conditions such as dim light, background image disturbance, and partial template occlusion. Sign In or Create an Account.

Structures such as buildings, bridges, dams, wind turbines etc. Choosing an appropriate monitoring system is important for determining any critical damage to a structure and address that to avoid any adverse consequence. Structural Health Monitoring SHM has emerged as an effective technique to monitor the health of the structures. SHM refers to an ongoing structural performance assessment using different kinds of sensors attached to or embedded in the structures to evaluate their integrity and safety to help engineers decide on rehabilitation measures.

Structural sensing, health monitoring, and performance evaluation

Плечи его отчаянно болели, а грубый камень не обеспечивал достаточного захвата и впивался в кончики пальцев подобно битому стеклу.

И, как бы повинуясь неведомому сигналу, между стенами слева от него мелькнула тень. Нет сомнений, что человеческий мозг все же совершеннее самого быстродействующего компьютера в мире. В какую-то долю секунды сознание Беккера засекло очки в металлической оправе, обратилось к памяти в поисках аналога, нашло его и, подав сигнал тревоги, потребовало принять решение. Он отбросил бесполезный мотоцикл и пустился бежать со всех ног.

Хейл мог понять смысл лишь двух слов. Но этого было достаточно. СЛЕДОПЫТ ИЩЕТ… - Следопыт? - произнес.  - Что он ищет? - Мгновение он испытывал неловкость, всматриваясь в экран, а потом принял решение. Хейл достаточно понимал язык программирования Лимбо, чтобы знать, что он очень похож на языки Си и Паскаль, которые были его стихией.

Распадающиеся материалы и нераспадающиеся. Есть целые числа, но есть и подсчет в процентах. Это полная каша. - Это где-то здесь, - твердо сказала Сьюзан.

Никто ни в чем его не обвинит. Он сам расскажет о том, что случилось. Все люди умирают… что значит еще одна смерть.

Коммандер, как всегда, прав. Им необходим ключ, который хранится у Хейла. Необходим прямо. Она встала, но ноги ее не слушались.

Хейл его отключил. И Сьюзан принялась объяснять, как Хейл отозвал Следопыта и как она обнаружила электронную почту Танкадо, отправленную на адрес Хейла. Снова воцарилось молчание. Стратмор покачал головой, отказываясь верить тому, что услышал.

 Какой-то турист. - Вы уверены. - Туризм - моя профессия! - отрезал Клушар.  - Я их сразу узнаю. Он гулял в парке с подружкой.

Створки стали стремительно сближаться. Стратмор попытался их удержать, но не сумел. За мгновение до того, как они сомкнулись, Сьюзан, потеряв равновесие, упала на пол за дверью.
