The Effect Of Earthquake Characteristics On The Collapse of Historical Masonry Buildings: Case Study of the Mosque of Takiyya Al-Sulaymaniyya

Different factors influence the collapse behaviour of masonry structures, and one of the major factors is the characteristics of the earthquake itself. This effect is
going to be more complicated for historical constructions, which involve
different structure members with different geometries.
The present study focuses on the effect of earthquake characteristics on the
collapse behaviour of historical masonry structures. The effect of earthquake
direction and the frequency content of the earthquake are discussed. A brief
background of the selected case study and modelling process are given first, and
the geometry of the whole structure is created where micro modelling strategy is
employed. The collapse analysis of the structure is performed under an artificial
model based on the earthquake characteristics. Unidirectional earthquakes are
applied to the structure from different angels in order to investigate the weakest
situation. Finally, different earthquake models are generated with different
frequency contents according the soil profiles and applied consequently on the
structure to explore the worst situation.
