Investigation of Soil-Structure Interaction for Design of Reinforced Concrete Structures under Earthquake Load
Abstract
One of
the most common natural disasters in our country is earthquakes with strong
ground motion. Earthquake damages structures with the impact of ground shaking.
Prediction of earthquake magnitude in advance is a great importance in the
civil engineering discipline to minimize possible damages during the earthquake.
Therefore, understanding of structural behavior correctly is as important as
the estimation of the possible earthquake magnitude. For this reason,
structures should be modeled accurately and realistically. Reinforced concrete
structures are usually designed using commercial software defined either as
rigid or with elastic springs at the base. In this study, considering the earthquake
recording of 1999 Kocaeli, a 12-storey reinforced concrete structure was
analyzed with rigid foundation assumption, Winkler and Modified Vlasov models. An
interface was coded in MATLAB to exchange data between SAP2000 and MATLAB.
Thanks to the interface, SAP2000 has gained the ability of performing analyses
with modified Vlasov model. In this way, periods, base shear forces, column
axial forces, column bending moments and lateral displacements of the
structures were compared for each subsoil model. At the end of the study, it is
observed that the effect of subsoil on the structural behavior is an
indispensable design factor for the reinforced concrete structures.
