Effect of Shear Wave Velocity of Soil on Behavior of Mid-Rise Reinforced Concrete Frame Structures

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.
