Abstract

It is known that one of the major problem faced by the structural engineers are the earthquakes. Because earthquakes are the natural events whose charasteristic, location and magnitude are unique. It is explicit that, in the earthquake resistant design, it is fundamental to select the structural form of a structure. Moreover, in order to obtain more realistic results, nonlinear effects must be taken into account such as material nonlinearity and geometric nonlinearity.

   The objective of this study is to investigate nonlinear behaviors of 3D structures under the earthquake loads with different stiffening members such as shear walls and bracings by using the time history analysis. The comparisons are made separately for lateral displacement, normal stress and maximum relative storey displacement. Besides, the first six periods of the systems are determined and the results are compared with each other.

   It is concluded that all of the stiffening members considered reduce the lateral displacement of the structures and  maximum relative storey displacement.
