Safety analysis of a cultural heritage structure has been performed. After a making a detail account
of past alterations, damage and present state, a 3D numerical model of a typical bay of the
structure had been prepared in GID (ver. 8). To implement a realistic behaviour of material, a nonlinear
material model so called tension compression distributed damage model has been utilized.
Analysis has been performed in COMET. The results include analysis both for gravity load and
seismic load. An overall assessment of the ultimate vertical load carrying capacity (although a little
realistic but gives a sense of safety psychologically) and structural behaviour at an earthquake
demand displacement has been done to explain the safety condition of the structure
