Objective To develop a methodology and quantitative tools for quantitativeassessment of the seismic vulnerability of masonry gravity dams.Survey of masonry materials properties commonly used in existingeuropean masonry gravity dams. Definition of constitutive lawfor stone masonry laboratory testing on large-scale intervalfilling materials specimens. Full-scale dynamic experimentalinvestigation on typical masonry gravity dam. Numericalmodelling of seismic behaviour of dams. Improvement andvalidation of simplified methods. Identification of safetycriteria and upgrading possibilities.The quantitative assessment of the seismic vulnerability ofmasonry gravity dams will be achieved by experimental, numericaland theoretical approaches.First, the hysteretic behaviour of the masonry under cyclicloadings will be analyzed with the data on masonry walls orpanels, available in literature, and with appropriate laboratoryand in-situ tests performed. Based on this analysis, a newconstitutive law will be developed: it should be able toreproduce qualitatively and quantitatively the observed rheologyof masonry, and its parameters can directly refer to practicalengineering concepts. The associated methodology to determinethe parameters will be applied to some laboratory tests onmasonry panels to validate the developed model.Second, the dynamic response of a masonry gravity dam whensubjected to seismic loading will be analyzed numerically inorder to select the most significant key factors. This selectionand the results obtained with this numerical model, especiallythe shape of the eigenmodes of the dam, will guide the specificdevelopment of a simplified method, that is required to provide afast and reliable assessment of the vulnerability of the wholestructure. Therefore it should be able to take into account thekey factors in a simple formulation. With the previously definedsimplified model the parametric analysis may be improved andcompleted.Third, full-scale forced vibration experiments shall be conductedon a typical masonry gravity dam. These experiments allow forthe investigation of the actual dynamic structuralcharacteristics which basically govern the seismic behaviour ofthe dam in the elastic range; Full analysis of the prototype damwill be performed with the numerical tools and with thesimplified method developed previously. For each method, thedomain of pertinence will be defined according to theexperimental tests and/or amplitude of seismic damages(irreversible displacements or deformations).The final goal is to provide safety criteria for evaluatingseismic vulnerability of masonry gravity dams and to propose someremedial measures of reinforcement if necessary. The output ofthis project could be used as basis for a future European damsafety standardisation.
