Abstract
MEO Arena building is one of the largest indoor arenas of the European Union and the largest one in Portugal. Due to its large capacity and unique structural characteristics, being composed of an inner wooden structure covered by a metallic roof, displacement measurements for structural health monitoring of the building is of utmost importance. This paper presents a method for displacement analysis of its metallic roof based on displacements acquired through Persistent Scatterer Interferometry and on geodetic measurements of the inner wooden structure. Regression models are used to estimate geodetic measures for the time of the SAR observations. Displacements of the metallic roof show a high correlation with temperature.
