Probabilistic seismic risk assessments (PSRA) are used to quantify the seismic damage probability of complex engineering structures due to seismic events. In such systems, the seismic capacities of individual relevant components are determined by structure mechanics. A significant digits computation method to quantify the mean seismic failure probability (fragility) for given component capacity...

Recent advancements in the area of structural dynamics have allowed civil engineers to better understand and control the response of structures to natural hazards, such as earthquakes and hurricanes. The social and economic impacts of natural disasters are continually increasing due to population growth and increasing number of older buildings with time. Through hazard mitigation engineers are ...

development of new methods in seismic analysis and increasing application of performance based seismic design necessitate the study of the seismic performance of structures designed based on iranian regulations. in this study the seismic performance of steel moment-resisting frames designed based on the tenth code of the iranian national building regulations is investigated. frames are differen...

This research focused on developing reliability-based seismic retrofit assessment procedures for highway bridge columns. Fragility curves were developed to assess the relative performance of various retrofit methods considering several limit states. Analytical fragility curves are developed from scaled earthquake records and structural response models. A simplified, single-degree-of-freedom (SD...

A tsunami is a natural disaster that destroys structures and kills many lives in countries the world. risk assessment of building under loading thus essential to evaluate damage minimize potential loss. crucial tool fragility curve. Most curves for force were developed using survey damaged data. This research proposed method developing based on analytical model In development, generic was one-s...

Nearly all residential houses were damaged due to 6.5 Mw earthquake in Pidie Jaya, 2016. The state of damage can be slight, moderate, and even extensive which lead the collapsing. confined masonry structure, commonly found Aceh, especially for housing construction, seemingly prone excitation. In this paper, analytical-based fragility curves are employed typical house structure. To account vario...

Seismic fragility analysis of bridges can be used to identify the probability different damage states under earthquake hazards. This study aims generate curve highway in Tehran, Iran, where these curves are not provided yet. To derive new curves, from studies all around world has been classified into categories, based on their structural designs, bridge materials, country, and analytical method...

Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...
