چکیده
in this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real iranian earthquake records by considering soil-structure interaction. then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of iran, atc-3, new zeland, canada, mexico, australia and ec8. finally, a formula for design eccentricity is proposed, regarding some important structural parameters.

متن کاملEvALVATION OF TORSIONAL PROVISIONS IN SEISMIC CODES
The effects of plan asymmetry on the earthquake response of code designed, one-story systems are identified with the objective of evaluating how well these effects are represented by torsional provisions in building codes. The earth quake-induced deformations and ductility demands on resisting elements of asym metric-plan systems, designed according to several different codes, are compared w...
متن کاملEvaluation of Seismic Behavior of Steel Moment Resisting Frames Considering Nonlinear Soil-structure Interaction
In structural analysis, the base of structures is usually assumed to be completely rigid. However, the combination of foundation and the subsurface soil, makes in fact a flexible-base for the soil-structure system. It is well-known that the structural responses can be significantly affected by incorporating the Soil-structure Interaction (SSI) effects. The aim of the present study is to provide...

The main purpose of the present work is to investigate the impact of soil-structure interaction on performance-based design optimization of steel moment resisting frame (MRF) structures. To this end, the seismic performance of optimally designed MRFs with rigid supports is compared with that of the optimal designs with a flexible base in the context of performance-based design. Two efficient me...
