Description
The importance of SSI is observed when a high rise building rests on soft subsoil where there is a need to estimate deformations caused by application of high loads from earthquake time histories. In simulation of SSI problems it is of great importance to select the most reliable time histories which would reliably adhere effects in the simulation problems.
Within this paper a ten storey frame structure was analyzed considering soil structure interaction. The site specific uniform hazard spectrum is used as target spectrum in selecting and scaling of earthquake records as an input in nonlinear dynamic analysis. For analyzing of the selected structure, several earthquake time-histories are used and obtained results were compared and discussed.
Calculation analysis of the frame structure considering spectral analysis and time histories of several different earthquakes reveal several conclusions. Firstly, the spectral analysis considers various frequency content although analysis is limited to linear analysis. On the other hand, the selected earthquakes are in time domain and can be used in non-linear analysis. The results obtained from the analysis show that correctly selection of earthquake time histories has important influence on the results and have to be considered in simulation of soil structure interaction problems
