| Paper title: | Determining the ultimate safety of historical structures |
| Authors: | Unay A Y, Atimtay E |
| Summary: | Historical structures are among the remains of our rich cultural heritage. They should be valued and well preserved. The typical historical structures is very rigid. Consequently, they have important enemies; foundation problems and earthquakes. Such structures being centuries old, they have gained equilibrium of soil-foundation-structure interaction, so no support movement is to be expected. However, earthquakes still pose an everlasting danger, as they have destroyed so many historical structures in the past. How safe is a historical structure under a major credible earthquake? This question can be answered by determining the load effects on the structure and the strength capacity. The ratio of strengthlload effect will yield a quantitative safety factor. The dynamics analysis of the three dimensional structure is performed. Then, the structure is discriticized to single out the vulnerable elements. The arches and piers Seem to be the elements most susceptible to failure. The strength interaction diagram are developed between normal forces and moments for the vulnerable piers and arches. Thus, the factor of safety for the total structure can be determined. The method of analysis has been applied to Mihrimah Mosque of Master Architect Sinan (1565). The results show that the piers and arches are very safe under own weight, the factor of safety being in the range of 56. Under the credible earthquake, the factor of safety is reduced, but still adequate as 2-3. |
