“…The mechanical properties of the constituent materials are shown in Table 2. The characteristics of the masonry constituting the walls and the pillars were based on the literature [28], while the mechanical properties of blocks and joints were chosen as the ones that led to a balance configuration at the beginning of the pushover analysis. A more accurate evaluation of the structural behaviour of this macroelement will be feasible when the actual values of the material properties will be available from the SEISMO Project.…”

The protection of historic masonry structures against earthquakes constitutes a rather complex problem. The calculation of their anticipated response involves significant difficulties, such as the selection of the proper simulation in conjunction with the measurement of the materials mechanical properties. In the present research the central church (Catholicon or Katholikó) of the Monastery of Kaisariani located on a hillside at the foot of Mount Hymettus on the east of Athens, Greece, is selected as a case study of a historic structure to study its seismic response. The Catholicon is a Byzantine crossed-dome church constructed during the 11 th /12 th centuries. Full survey and detailed in-situ and laboratory tests were carried out by the multidisciplinary team of an ongoing research program in order to document its geometry, the construction details and the mechanical properties of the constituent materials. The current condition of the structure and its seismic behavior were assessed by means of a blockjoint and kinematic analysis. Specifically, the stability of selected macroelements was evaluated through (a) pushover analysis applied to block-joint models of arches and vaults and (b) kinematic analysis of rigid bodies.
