Özet:

 

The typical housing type of the rural population of Turkey  is load-bearing masonry units.  Masonry buildings are as vulnerable to  seismic failure as reinforced concrete buildings.  However, the  majority of research efforts are directed towards reinforced concrete  buildings.    Masonry walls that constitute masonry structures are subject to  in-plane and out-of-plane seismic forces during an earthquake.  It is  shown in this paper that out-of-plane acceleration can exceed in-plane  accelerations.  Therefore, it is very possible that masonry buildings  begin to fail by collapse of upper story walls subject to out-of-plane  accelerations.    My masonry wall loaded out-of-plane fails by forming fracture lines  similar to the yield lines of a 2 way reinforced concrete slab.  Of  course, the failure of the masonry wall is brittle.  The fracture  lines of a masonry wall loaded out-of-plane form rather quickly and  the applied load is reduced.  As such, the masonry wall loaded  out-of-plane does not seem to have enough ductility to justify the use  of a seismic force reduction factor of Ra(T1) = 2.5 as specified  by the Turkish Earthquake Code.
