Effect of near-fault earthquakes on a historical masonry arch bridge (Konjic Bridge)
Memduh Karalar and Mustafa Yeşil

 
Abstract
    In this study, it is aimed to investigation the performance of historical arch bridge under near fault earthquakes with the finite element method (FEM) and to demonstrate the capability and performance estimation. For this purpose, Konjic Bridge constructed in the Bosnia and Herzegovina is selected. To investigated the behaviour of near fault earthquakes on Konjic Bridge, first, FEM of the Konjic Bridge is built and analyzed under various near fault using the program ANSYS. To build FEM, 647894 nodes and 215464 elements are used in ANSYS. Then, near-fault earthquakes are taken into accounted (Chi-Chi 1999, Imperial Valley 1979, Superstation Hill 1987, NorthRidge 1994, Cape Mend 1992, Kobe 1995). The maximum displacement values, principal stresses and elastic strain values are compared with the help of contour diagrams. As a result of these analyzes, it is seen that the arch of the historical masonry arch bridge has more effect on the structural behavior of the historical masonry arch bridge. Furthermore, it is obviously seen that under the near fault earthquakes, the tensile stresses, especially on the top, bottom and side of the large belt, reached the allowable tensile strength of the wall under the near fault earthquakes. There may also be a risk of damage due to these stresses.
