Abstract :
Bearing wall structures (known as tunnel forms), are used in earthquake-prone areas because of their acceptable seismic performance and high construction speed. It should be mentioned that seismic codes did not specifically focus on these types of structures. As a result, tunnel form buildings are designed similar to structures including shear walls due to relevant codes. In this study, the seismic performance of high-rise tunnel form buildings have been investigated. For this purpose, three structures of 15, 20 and 25-story with this seismic system have been modelled and examined using fiber elements and nonlinear static and dynamic analysis are conducted on these structures. The focus of this study is on the ductility of the structures. The impact of axial force on the ductility ratio is investigated and the ductility demand is calculated for assumed structures.
