Abstract:
The design of structures against wind and earthquakes due to losses caused by these phenomena in different countries is very important. Designing of tall buildings should be have comprehensive and complete against the forces of wind and earthquake. Earthquake is one of the world's natural phenomena, so that in recent years the human losses during 1947 and 2005 have been announced about 550 thousand people worldwide. The main goal of this study is to investigate the behavior of resistant reinforced concrete core in high-rise building of the tube in tube system with stairs against earthquakes in building with 100 meters height and 25 floors under the influence of three Accelerogram Bam, Tapas and Northridge via SAP2000 software. Base shear, roof displacement and column axial force compared together. The results of the research showed that modeling stepping on the coordinates of the center of mass has not made a significant change, but rigidity center has mainly changed due to stiffness of stair slab. Also high-rise building's seismic response affected by the earthquake Accelerogram type
