چکیده
Abstract The development of fragility functions that express the probability collapse a building as function some ground motion intensity measure is an effective tool to assess seismic vulnerability structures. However, number factors ranging from selection modeling decisions can influence quantification probability. A methodical investigation was carried out examine effects component and in establishing demand risk typical reinforced concrete frame building. primary system considered this study modern 6-story RC moment designed current code provisions seismically active region. Both concentrated distributed plasticity beam–column elements were used model several options constitutive for both options. Incremental dynamic analyses (IDA) using two suites motions—the first set comprised site-dependent motions, while second compilation hazard-consistent motions conditional scenario spectra approach. Findings highlight characterization various levels.

Probabilstic Seismic Risk Evaluation of Rc Buildings
As more and more emphasis is being laid on non-linear analysis of RC framed structures subjected to earthquake excitation, the research and development on both non-linear static (pushover) analysis as well as nonlinear dynamic (time history)analysis is in the forefront. Due to prohibitive computational time and efforts required to perform a complete nonlinear dynamic analysis, researchers and d...
متن کاملSeismic Vulnerability Assessment of Existing Rc Buildings in Gis Environment
With rapid population growth over the past 30 years and no significance seismic activity during this period, the unchecked development of the built environment in Bangladesh has been resulted in little resilience to earthquake. Identifying buildings due to this unchecked development that has high vulnerability is of critical importance both for reliable loss estimation as a result of an expecte...

by identifying the damage index of a structure, in addition to a correct understanding from real behavior of the structure, the required criterion for strengthening would be given. researchers have given many relations for determination of damage index but such relations have been based upon laboratory methods which challenge their usage in a broad term. in this paper two new methods are given ...
متن کاملSeismic fragility assessment of RC moment resisting frame buildings designed for different editions of Iranian seismic design code
Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...
