Nonlinear Seismic Assessment of Historical Masonry Karaz Bridge Under Different Ground Motion Records

Abstract

The most significant artifacts that transfer the cultural heritage of past civilizations to the present are historical structures. Historical bridges are of great importance in terms of transportation, trade and architecture from past to present. Some of these structures have been destroyed by natural disasters or have suffered significant structural damage. Especially earthquakes cause damage to these structures. In this study, the earthquake behavior of the Historical Karaz Bridge was investigated. The structural elements of the bridge and the materials connecting the bearing elements were evaluated together with the macro modeling approach. For this purpose, a 3D finite element model of the bridge was generated and its seismic behavior under different ground motion records was investigated by nonlinear analysis. Analyzes were carried out using the ground motion records of Bingöl, Elazığ, Erzincan, Van and Gölcük, and the results were evaluated mutually. In the analysis results, the dynamic behavior of the bridge was evaluated over the distribution of displacements and stresses and the earthquake behavior was investigated.

Investigation of Seismic Behavior of the Historical Yeşiltepe Bridge

“…The precise determination of material properties is of great importance for the theoretical analysis of structures with a long history, such as historical bridges. Due to the difficulties in determining the material properties of these structures, existing studies in the literature were examined to determine the relevant material properties [13,17,18]. Table 1 presents the fundamental physical and mechanical properties of the materials under consideration in this research.…”

Implications of Arch Warp Altitudes on an Ancient Masonry Bridge under Ground Movements

“…The material properties expended in the analyses are presented in Table 1 [1]. The Concrete Damage Plasticity (CDP) model is implemented to simulate the non-linear behavior of the wall [53]. Though originally established to define the non-linear performance of concrete [54,55], the usage of such a model for masonry is generally accepted in studies after the key restrictions are properly adapted.…”

“…Though originally established to define the non-linear performance of concrete [54,55], the usage of such a model for masonry is generally accepted in studies after the key restrictions are properly adapted. The CDP model is a damage model on the basis of the continuous plasticity, permitting changed tensile and compressive strength as in the wall, with changed damage parameters in stress and compression [53]. On the FE examination, the exact description of the border conditions along with the material model is of great importance.…”

Structural Assessment of Historical Stone Bridges with the Finite Element Method under Dynamic Effects of Arch Shape: The Antik Iscehisar Bridge

“…According to the findings of the earthquake study, the K10 arch, which is one of the arches on the bridge with the biggest arch span, saw the greatest amount of deformation as a consequence of the earthquake. The seismic activity of the Historical Karaz bridge was investigated by Nemutlu et al [19]. In order to achieve the objective, a 3D FEM of the bridge was created and its response to seismic activity was examined using nonlinear analysis using various ground motion recordings.…”
