The Dynamic Flexibility Method in Structural Dynamics: Application to Nonuniform Beams and Plates and to Cavity-Backed Plates
… linear structures employing elemental dynamic flexibility formulation. This dissertation is divided into three parts. In the first, the elemental flexibility formulation is developed for Euler-Bernoulli beams having discontinuous section properties, which can be viewed as the synthesis of …

Previsão do comportamento estático e dinâmico de estruturas de máquinas operatrizes
The flexibility method is formulated with an immediato application to the stitic and dynamic analysis of mochine tool structures. There is also presented a computer program for predicting from design drawings the static deformations and the natural froequencias and modes of vibration of such …

Interação estaqueamento - meio homogêneo
A genral method of solution for vertically loaded pile groups, embedded in an homogeneous linear elastic medium, is presented in this work, with the intention of predicting displacents, rotations and forces distribution along the piles, considering pile-soil interaction. The present analysis is …

Methods for Structural Health Monitoring and Damage Detection of Civil and Mechanical Systems
… the structure. Over the past few years various methods for monitoring the condition of structures have been proposed. With respect to civil and mechanical structures several methods make use of modal parameters such as, natural frequency, damping ratio and mode shapes. In the present work four …

The development of a new comprehensive management model for Apophysitis Syndromes in adolescents, based on the assessment and management of passive muscular tension
… muscular tension as demonstrated by reduced flexibility. Method: A new theoretical model of passive and active tension underlying AS is proposed and used to demonstrate the new approach. Four main studies are presented. The first study examined a novel treatment of the most common AS in …

Dynamic performance of pre-cast prestressed beams – cast in-situ slab composite bridges
… techniques such as ultrasonic techniques, radar method, impact testing, magnetic based methods and proof load tests are limited to small areas, time consuming and require prior knowledge of the damaged zone. These limitations can be overcome by using dynamics-based techniques. The main objective …

Development of a long-term, multimetric structural health monitoring system for a historic steel truss swing bridge
… networks themselves. Statistical process control methods were established to detect anomalous behavior in the short and long term time scales. Methods to locate and quantify the damage that has occurred in the structure once an anomaly has been detected were demonstrated. One of the methods …
