Abstract

The seismic behavior assessment of structures is carried out to estimate the damages caused by the earthquake. In recent years, with the advances of earthquake engineering, knowledge enhancement and experience in the seismic behavior of structures, novel methods have been proposed for evaluating the seismic behavior of structures and it needs to be defined as Damage Index. Which report the failure rate quantitatively and qualitatively. In many cases, the damage indices are dimensionless parameters whose amplitude is usually between zero for the no-damage state and one for the structural collapse state, and the values between these two are different failure states. Until now, various damage indices have been proposed based on various structural criteria such as: ductility, Deformation, displacement, rotation, curvature, stiffness, softness, period, frequency, hysteresis Energy or combined. Considering the characteristics of each one, selecting the appropriate Damage Index is a fundamental question for the design and suitability of the structure to estimate the failure rate with high reliability. In this study, in order to investigate the performance of Deformation and Energy parameters individually and in combined state (Park-Ang) in evaluation of seismic damage indices of steel structures, 6 Moment Steel Frames with special ductility, regular geometry and 4, 7, 10, 15, 20 and 25 story were designed in SAP2000 software and nonlinear time history analyses were performed under Near-Fault Records using OpenSees software. Then the values of the damage indices are calculated based on the Deformation, Energy and combined parameters. The results provide a quantitative assessment of the damage of the frames, stories and the role of these two parameters in numerical values of damage indices. The results show that the more effective role of the Deformation of the elements in the seismic failure rate.
