Turkey is a country that is susceptible to earthquakes Seismic Performances and has experienced many principal earthquakes that absolutely destroyed or caused huge harm to numerous historic systems. nowadays, using pc software, it is critical to numerically model and examine historic structures that want huge recovery and strengthening, to assess them from a angle of seismic resistance, and to reinforce them without changing their originality. in this have a look at, a finite detail model of the historical Tigris Bridge on the Tigris River become created. First, the stresses and deformation Seismic Performances due to its own weight had been decided. ultimately, dynamic analyses have been carried out in the time area using beyond earthquake ground motion statistics. Displacement and strain values acquired for every earthquake file in these time domain analysis were in comparison to each different to assess the seismic behavior of the bridge relatively. The seismic performance of the bridge changed into decided on the basis of the “hints at the control of Earthquake dangers for historic structures” posted by Seismic Performances using the Directorate popular of non secular Foundations in Turkey.
The historic Tigris Bridge in Diyarbakır is an essential and outstanding shape in terms of its length and structure and has end up a symbol of the stated city. The bridge is three km from the city middle and is located at a point that links the middle of the town to the Township of Bağıvar and several villages. numerous critiques were expressed approximately the date whilst the bridge become first built. in step with Van Seismic Performances Bercheh and Albert Gabriel, every other bridge stood within the modern vicinity of the Tigris Bridge in ancient times [1] . An epitaph stating that in Diyarbakır, which got here below Islamic rule in 639, Umayyad Caliph Hisham started repairing a collapsed bridge in 742 – 743 and that the construction work stopped after his loss of life. it’s also regarded that the japanese armies of the Roman Empire besieged Diyarbakir unsuccessfully in 974 and they destroyed this bridge once they withdrew [2] .
The bridge is assumed to were destroyed and Seismic Performances rebuilt in part or absolutely several instances. The maximum latest and most correct acknowledged creation date of the bridge is primarily based at the inscription marked at the bridge. consistent with this inscription, the bridge became built in 457 A.H. (1065 advert).
