It is a known fact that local ground conditions affect the seismic behavior of structures. Finally, with the earthquake resistant building design principles updated in 2018, local soil classes have also changed. At the beginning of these changes is that it brings new calculation approaches specific to situations where the ground is weak and high-rise buildings. Moreover, these special accounts are required to be controlled by experts. Considering the local soil conditions in the current earthquake code, the section effects under earthquake effects were obtained for a plane frame in a reinforced concrete structure selected as an example. At any geographical point in the province of Bitlis, the variation of earthquake parameters was examined for five different local soil classes (ZA, ZB, ZC, ZD and ZE). Short map spectral acceleration coefficients, maximum ground acceleration, maximum ground velocity, spectral acceleration coefficients, horizontal and vertical elastic design acceleration spectrum corner periods were obtained for each soil class. Using the values obtained for each local soil class, calculations were made for a two-storey reinforced concrete structure and the earthquake cross-section effects were calculated. With this study, the effects on earthquake parameters and cross-section effects were calculated by taking into account the change in soil classes in the new regulation.
