Structural Health Monitoring of Bridges and Buildings in Africa: Challenges and Difficulties

ABSTRACT: The steel and mixed construction sector is growing worldwide due to the obvious advantages of steel structures in comparison to reinforced concrete structures. To ensure this trend, it is necessary to clarify some of the drawbacks that are normally wrongly linked to steel constructions, namely those related with corrosion, fire resistance and fatigue. One … Continue reading Structural Health Monitoring of Bridges and Buildings in Africa: Challenges and Difficulties

A novel approach in the life cycle assessment of engineering structures

ABSTRACT: Structural Health Monitoring (SHM) is fundamental for the assessment of the behavior of existing and new structures under service conditions. It is most suitable to identify the initiation of deterioration and to validate design hypothesis such as load distribution paths, bond between materials, composite action between precast members and cast-in-place parts, among others. The … Continue reading A novel approach in the life cycle assessment of engineering structures

Management of the Production of Metal Structures: Computer Application – “MERP”

ABSTRACT: Most software for the management of the production of metallic structures has its field of action limited to work in the factory, not allowing for the monitoring of subcontractors – in the other words, execution done “out of doors”. The vast expertise necessary to manufacture a steel structure and the increase of distance between … Continue reading Management of the Production of Metal Structures: Computer Application – “MERP”

Development of a Structural Health Monitoring System

ABSTRACT: Structural Health Monitoring (SHM) is fundamental to identify the structural behavior, in particular of special structures, allowing the validation of design hypothesis, the development of more economical solutions and the prediction of deterioration. In general, the existing structural health monitoring systems present a high cost when installed in current structures. In opposition to this … Continue reading Development of a Structural Health Monitoring System
