Experimental modal identification of an existent earthen residential building

The paper presents the preliminary round of in-situ experimental tests carried out at “Hotel Comercio”, a historical construction located at the historical centre of Lima (capital of Peru). The building is a three story republican-type construction built at 19th Century with composite structure of Adobe and “Quincha”. The experimental works consisted on Operational Modal Analysis (OMA) tests aiming at identifyi...

Prototype WSN platform for performing dynamic monitoring of civil engineering s...

Structural Health Monitoring represents the present and future of the civil engineering since, until few years ago, structural diagnosis works had been performed with few resources regarding to experimental techniques. Precisely in the field of monitoring sensors, the progress of new technologies based on wireless communications and Micro-Electro-Mechanical- Systems (MEMS) are of high interest for replacing the...

A wireless sensor network platform for structural health monitoring: enabling a...

Structural health monitoring has long been identified as a prominent application of Wireless Sensor Networks (WSNs), as traditional wired-based solutions present some inherent limitations such as installation/maintenance cost, scalability and visual impact. Nevertheless, there is a lack of ready-to-use and off-the-shelf WSN technologies that are able to fulfill some most demanding requirements of these applicat...

Dynamic identification and monitoring of St. Torcato Church

The paper is related to the San Torcato Church, in Guimarães, Portugal. At the moment, the church has significant structural problems due to soil settlements. Cracks can be observed on the main and the lateral façades, the bell-towers are leaning, and the arches in the nave exhibit a failure mechanism with cracks and vertical deformations. Non-stabilized phenomena are present in the structure. To stabilize the ...

Complicações precoces no tratamento ortopédico das metástases ósseas

OBJETIVO: Avaliar as complicações precoces do tratamento ortopédico de lesões ósseas metastáticas e os fatores associados a essas complicações. MÉTODOS: Foram avaliados retrospectivamente 64 pacientes submetidos a tratamento cirúrgico de metástases ósseas, analisando as complicações ocorridas no peroperatório e pós-operatório precoce e associando-as com a origem do tumor, o tipo de procedimento realizado, a nec...

Operational modal monitoring of ancient structures using wireless technology

Operational Modal Analysis is currently applied in structural dynamic monitoring studies using conventional wired based sensors and data acquisition platforms. This approach, however, becomes inadequate in cases where the tests are performed in ancient structures with esthetic concerns or in others, where the use of wires greatly impacts the monitoring system cost and creates difficulties in the maintenance and...
