Nonlinear Seismic Analysis of Steel Moment Resisting Frames Considering Soil-Structure Interaction Effect with the Endurance Time Method
, M.Sc. Thesis Sharif University of Technology ; Ghannad, Mohammad Ali (Supervisor) ; Esmaeil Pourestekanchi, Homayun (Co-Advisor)
Abstract
Dominance over the seismic behavior of structures leads to proper design and the cost reduction of structures according to the structures demand performance. In this regard, the issue of performance-based seismic design of structures has been proposed in which the nonlinear behavior of structures is the basis for the design and evaluation of structures during earthquakes. Moreover, regarding of soil under the structures will change the elastic and inelastic behavior of structures; also, the effects of soil-structure interaction on the seismic performance of structures should be considered to achieve the real behavior of structures. Hence, the purpose of this study is to evaluate the...

Abstract
The preliminary design of building structures is normally based on the equivalent lateral forces provided in seismic design guidelines. The height-wise distribution of these loads is predominantly based on elastic vibration modes. However, as structures exceed their elastic limits in severe earthquakes, these design load patterns may not necessarily lead to efficient distribution of strength within the structures. To address this issue, several alternative load patterns have been proposed for the seismic design of non-linear structures. However, due to the simplifications involved in the development of these design load patterns, their adequacy needs to be assessed for different structural...
