摘要

This work concerns the problem of simulating numerical y the behaviour of dry joints in megalithic structures, and specifically the stone monuments of ancient Greek architecture. In principle, the design of an ancient Greek temple approximates that of a rock structure w th big voids and individual structural members of discontinuous rock mass with dry joints, in which the major deformation takes place along the joints. The work uses experimental data from full-scale tests at the Laboatory for Earthquake Engineering of NTUA, involving slow cyclic sliding motions along the interface of a two-drum system, and describes the formulation of a mathematical model using SAP2000 with 3-D solid elements and non-linear links. Using the recorded P-δ relationship the detailed stress distribution across the base of the column drum was evaluated. Stress concentrations revealed a corresponding shear-slide failure mechanism of the experimental set-up.
