Model-free data interpretation for continuous monitoring of complex structures
Civil engineering structures are difficult to model accurately and this challenge is compounded when structures are built in uncertain environments. As consequence, their real behavior is hard to predict; such difficulties have important effects on the reliability of damage detection. Such situations encourage the enhancement of traditional approximate structural assessments through in-service ...
متن کاملCombined model-free data-interpretation methodologies for damage detection during continuous monitoring of structures
2 3 Despite the recent advances in sensor technologies and data acquisition systems, interpreting 4 measurement data for structural monitoring remains as challenge. Furthermore, due to the 5 complexity of the structures, materials used and uncertain environments, behavioral models are 6 difficult to build accurately. This paper presents novel model-free data-interpretation methodologies 7 that ...
متن کاملModel Free Interpretation of Monitoring Data
No current methodology for detection of anomalous behavior from continuous measurement data can be reliably applied to complex structures in practical situations. This paper summarizes two methodologies for model-free data interpretation to identify and localize anomalous behavior in civil engineering structures. Two statistical methods i) moving principal component analysis and ii) moving corr...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Methodologies for model-free data interpretation of civil engineering structures
Structural Health Monitoring (SHM) has the potential to provide quantitative and reliable data on the real condition of structures, observe the evolution of their behaviour and detect degradation. This paper presents two methodologies for model-free data interpretation to identify and localize anomalous behaviour in civil engineering structures. Two statistical methods based on i) moving princi...
