EVALUATION OF THE SEISMIC BEHAVIOR OF THE HISTORIC CLANDRAS BRIDGE

Abstract

Historical masonry arch bridges are one of the most important structures that convey the cultural heritage of past civilizations to the present. Historical masonry arch bridges were one of the most important elements of transportation and architecture in the past. These structures can be damaged by many natural disasters such as earthquakes, floods, etc. from the past to the present. It is necessary to carry out the necessary studies in order to protect these bridges as they were built and to transfer them safely to future generationsIt is clear that determining the earthquake behavior of these bridges, which are exposed to different geometrical properties, materials and loading conditions, will increase the effectiveness of the strengthening works to be done. In this study, the seismic behavior of the Uşak Clandras Bridge, which is a historical masonry arch bridge, was investigated by linear and non-linear time history analysis. Firstly, the 3D model of the masonry bridge was created with the Abaqüs program. To simulate the more real behavior of the structure, a detailed survey was carried out. For the characteristic features of the materials used in the bridge, studies in the literature were taken into consideration. Acceleration records of 1999 Kocaeli Earthquake were used in dynamic analyses.
