dc.description.abstractThe purpose of this thesis is to evaluate the non-linear response of a wall-equivalent dual-system structure. The procedure of the analyses follows the guidelines incorporated in the current Norwegian seismic design code NS-EN 1998-1. The investigated structure is detailed for medium ductility in accordance to NS-EN 1998-1. A representative finite element model of the structure (2D) is created with SeismoStruct and OpenSees software packages with emphasis on capturing the non-linear behavior adequately. Both non-linear static analysis and non-linear time history analysis are executed to simulate earthquake for the structure in question. Over-strength and period-based ductility factors of the structure are assessed in accordance to FEMA P695 and the results confirmed that a conservative approach is incorporated in NS-EN 1998-1. Although the structure is detailed for DCM, the results from non-linear static analysis revealed that the structure response remained in the elastic range. Furthermore, in the latter analysis the software packages give excellent results in terms of target displacements and base shear forces. Non-linear time history analysis confirmed the results obtained from non-linear static analysis for displacements. Moreover, the importance of distribution of stiffness through the structure with regard to inter-storey drifts is demonstrated. The effect of a soft storey is investigated by increasing the height of the first floor. The results reveal that the inter-storey drifts highly increases at the lower stories rather than at the upper stories.
