Spectral evaluation of seismic fragility of structures
ABSTRACT: An approach for assessing the seismic fragility of inelastic structures is presented. In this approach, the structural response, which is evaluated from response spectra with an associated probability distribution, is compared with the performance limits states to assess fragility. Formulas that provide the probability distribution of spectral ordinates are developed based on the cros...
متن کاملAN OPTIMUM APPROACH TOWARDS SEISMIC FRAGILITY FUNCTION OF STRUCTURES THROUGH METAHEURISTIC HARMONY SEARCH ALGORITHM
Vulnerability assessment of structures encounter many uncertainties like seismic excitations intensity and response of structures. The most common approach adopted to deal with these uncertainties is vulnerability assessment through fragility functions. Fragility functions exhibit the probability of exceeding a state namely performance-level as a function of seismic intensity. A common approach...
متن کاملEffect of seismic sequences on fragility of Iranian code-conforming shear wall RC buildings
Background and objective: Estimating the vulnerability rate of urban textures in seismic incident following a major earthquake (aftershocks) is crucial in decision making and crisis management. For this purpose, it is necessary to calculate the vulnerability of buildings due to the successive incidents and to use them in the vulnerability estimation for probable future aftershocks. Seismic frag...
متن کاملSeismic Fragility Assessment of RC Frame-Shear Wall Structures Designed According to the Current Chinese Seismic Design Code
After learning from several devastating earthquakes in China in recent years, stricter design criteria have been introduced in the current Chinese seismic design code. To investigate the reliability of the current seismic design code, seismic fragility analyses were performed for 45 10-story reinforced concrete (RC) frame-shear wall structures designed according to the current Chinese seismic d...
متن کاملThe Effect of Axial Force Variations on Nonlinear Modeling and Seismic Response of Reinforced Concrete Structures
In order to increase the accuracy of evaluating seismic response of structures, it is critical to conduct dynamic analyses based upon precise nonlinear models being as consistent as possible with the real conditions of corresponding structures. The concentrated plasticity model including one elastic element and two nonlinear spring elements at both ends has been considered within the research c...
