The main purpose of this study is to compare the static and dynamic behavior of a historical single-span masonry arch bridge under different near-fault earthquakes. The historical Tokatlı Bridge, built in Karabük, is chosen for this study. To investigate the behavior of near-fault earthquakes on the historical masonry bridge, first, a finite element model is built and analyzed under various near-fault earthquakes by using ANSYS and SAP2000. To build a finite element model, 162920 nodes and 47818 elements are used in ANSYS. First, finite element analysis results are compared to each other under Earth gravity. Then, ground motions near the fault are chosen to be used in this study. These earthquakes can be listed as follows: Cape Mend (1992), Kobe (1995), Superstition Hills (1987), Northridge (1994), Imperial Valley (1979), and Chi-Chi (1999). The behavior of the single-span historical bridge is obtained under these ground motions, and the results are compared with each other using contour diagrams using ANSYS. Furthermore, at the end of these analyses, it is observed that the tensile stresses have reached the permissible masonry tensile strength, especially on the upper side of the large belt, on the upper side of the belt, and on the side of the belt, and pose a risk for damage.

近断层地震下历史托卡特勒大桥的地震行为研究

本研究的主要目的是比较历史单跨砌体拱桥在不同近断层地震下的静动力性能。本研究选择了建于卡拉比克的历史悠久的托卡特利大桥。为研究历史砖石桥近断层地震的行为，首先利用ANSYS和SAP2000建立并分析了各种近断层地震作用下的有限元模型。为了建立有限元模型，ANSYS 中使用了 162920 个节点和 47818 个单元。首先，有限元分析结果在地球重力作用下相互比较。然后，选择断层附近的地震动用于本研究。这些地震可以列举如下：Cape Mend (1992)、Kobe (1995)、Superstition Hills (1987)、Northridge (1994)、Imperial Valley (1979) 和 Chi-Chi (1999)。单跨历史桥梁的行为是在这些地面运动下获得的，并使用 ANSYS 使用等高线图将结果相互比较。此外，在这些分析结束时，观察到拉伸应力已达到允许的砌体抗拉强度，特别是在大带上侧、带上侧和带侧，并造成损坏的风险。
