Abstract

The most significant parameter of nonlinear time
history analysis is the quality of strong ground motion record which will be
used. In this paper, the near-field earthquakes including the forward
directivity which have been recorded from two different soil classes were
scaled in accordance with the design spectrum of probability of exceedance was
10%. Following this, the nonlinear time history analyses of a typical mid-rise reinforced
concrete frame structure were conducted by using the strong ground motion
records which were scaled.  As a result
of the analyses made, the shear force, bending moment and interstory drift
ratio curves of structures were acquired for each soil classes. By comparing
these curves acquired for different soil classes with each other, the effect of
soil characteristics on which the structure will be constructed on the results
were discussed. According to this, it has been observed that as the shear wave
velocity of soil decreases, internal forces and displacements in the structure
increase
