The Effect of Different Soil Classes on Earthquake Demands of Reinforced Concrete Structures: Case Study for Sakarya

In this study, it is aimed to investigate the effect of different soil classes on behavior structure under earthquake loads. An evaluation was made for five-storey and eight-story reinforced concrete (RC) frame structures considering three (ZC, ZD, ZE) defined in Turkish Building Earthquake Code 2018 (TBEC 2018) current hazard Sakarya. structural system RC frame, cross-section geometry reinforcement details columns beams were designed by design criteria TBEC 2018. While determining dynamic structure, effective bending rigidity column beam elements used. For model, base shear force, story displacements drifts investigated comparatively using mode superposition method SAP2000 finite element analysis program. When results are compared, seen that as stiffness decreases, force displacement demands increase.
