This paper describes a study conducted by LNEC to assess the health and safety conditions of the floor of the Noble Hall of the National Theater of São Carlos. In a multidisciplinary approach, an extensive field work was carried out, involving the identification of type and location of floor beams in the various areas of the floor using a Ground Penetrating Radar (GPR), local inspection openings to visually assess the geometry, timber species and conservation state of structural members at those points and assessment of the conservation state of timber beam ends, using drilling equipment. The tests performed are referred herein, the potentiality of using GPR, the results obtained with ground- and air- coupled antennas are analyzed and recommendations are made.
