Post-earthquake structural assessment using Ground Penetrating Radar (GPR): preliminary insight for guidelines from literature review
Abstract
Ground Penetrating Radar (GPR) is a Non-Destructive Testing (NDT) technique for quick and reliable post-earthquake structural assessment of buildings. GPR allows for identification of internal, hidden damage like cracks, voids, delaminations, and measurements of reinforcement integrity, which are often missed by visual inspections. Effective use of GPR depends upon careful planning, such as proper selection of antenna frequency depending upon the target and material being analysed. Though prompt and flexible, GPR has limitations such as shallow penetration in conductive targets and complex data interpretation. Therefore, integration with other NDT techniques can be required for a comprehensive and reliable building diagnosis. Standardized guidelines can support the reliability and effectiveness of GPR use in post-earthquake assessment. In this perspective, the article aims to provide some initial results through the analysis of literature in the field.
