چکیده | ||
Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid have been designed. Finally, the seismic performance of these models were investigated and compared to the horizontal hexagrid structure to obtain the optimum location of the transitional story. According to the analyses results, combining horizontal and vertical hexagrid cells can strongly affect the seismic performance of the structure. Thus, choosing the optimum location of transitional story, regarding design priorities, is of significant importance. | ||
