2008Columns and walls are main load-bearing elements of most historical masonry structures. In resisting seismic forces, the lateral stiffness of these elements is an important parameter. Earthquakes may cause cracks in the masonry and this reduces the lateral stiffness of the columns and walls. Using an efficient numerical method which takes into account the cracking and the second-order effects, this thesis investigates the lateral stiffness of unreinforced masonry columns with rectangular cross?section. On the basis of the obtained lateral force versus lateral displacement relationships, the behavior of the columns is characterized by two limit states corresponding to the first cracking and maximum resistance. For an example column, the lateral stiffness values at these limit states are determined and compared with each other. The results show that the lateral stiffness is directly related to the magnitude of displacement and hence the level of cracking. Moreover, implementing parametric analyses, the effects of some parameters such as; column slenderness, vertical top load to column self weight ratio, flexibility parameter, eccentricity of the vertical top load and the angle of tilt, if any, on the lateral stiffness of the column are also investigated.ŞAHİN, İBRAHİM HALİL
