Seismic  actions  have  been  a  great  challenge  for  structures  in  the  structural 

engineering community, and the need for further developments has been approved by 

catastrophic seismic events at each time. Reproducing the dynamic behavior of structures with 

an  acceptable  level  of  accuracy  is  a  complex  task  due  to  uncertainties  related to  the 

geometrical, material and physical structural system, more particularly, in the case of existing 

historical masonry structures. The use of dynamic analysis is a better choice than the use of 

static or quasi-static approaches since it is a better representation of the dynamic response of 

a structure by taking account of its energy dissipation capacity. The scope of the present paper 

is focused on a seismic assessment of a historical masonry structure, Kütahya Kurşunlu Mosque 

located in Turkey, before and after it has been retrofitted. The historical mosque is located in 

a  seismic  prone  zone  where  it  is  crucial  to  ensure  seismic  safety  of  structures  and  the  local community. Based on the condition of the structure reported from the site inspections, a seismi 

retrofitting  by  using  steel  girder  elements  was  implemented  on  the  structural  load-bearing 

walls. The effectiveness of the seismic retrofitting to the seismic response of the mosque was 

investigated  by  means  of  the  finite  element  method.  Three  bi-directional  nonlinear  dynamic 

analyses were performed by using real ground motion records aiming at the validation of the 

nonlinear  dynamic  response  of  the  numerical  model  in  terms  of  damage  patterns,  and 

demonstration of the contribution of the seismic retrofitting by comparing the representative 

model with its retrofitted counterpart. The comparison has been carried out in terms of peak 

displacement and damage patterns. It is found that the contribution of the seismic retrofitting 

is considerable for the out-of-plane displacements of the load-bearing walls. Furthermore, a 

good  correlation  between  existing  damage  and  the  numerical  damage  is  achieved,  and, 

therefore, the validation of the nonlinear response of the representative model is attained.
