Investigation of the contribution of soil conditions to damage and failure of RC structures in Adapazarı

During the 17 th August 1999 Marmara earthquake, the soil has played important role as a contributing factor in the failure of Reinforced Concrete (RC) moment resisting frame buildings built in Adapazari. In this study, the differences of contributing effects on the filure of RC buildings which were built in the soft soil such as Adapazari downtown and stiff soil such as Maltepe has been investigated. Various two dimensional soil-structure models are formed with the simulations of buildings, which had some irregularities suh as soft story, weak stoey and short column effect, and soil properties of Adapazari downtown and Maltepe. The dynamic analysis of the soil-structure models subjected to Marmara earthquake was carried out using SAP2000 software packet program. The outcomes of lateral top displacement of SSI models with respect to soil conditions were presented as graphs and the results were discussed.
