چکیده
abstract: Due to the paucity of studies regarding seismic assessment buildings in Brazil, this study aims present and discuss a reliability reinforced concrete framed structure designed according Brazilian standard ABNT NBR 6118:2014 without consideration design requirements 15421:2006. Herein, fragility functions are generated through probabilistic demand analysis, integrated with hazard curves for Northeastern Brazil generate regional failure probability maps three limit-states: Immediate Occupancy (IO), Life Safety (LS), Collapse Prevention (CP). The results indicated that building performance is adequate IO; however, LS CP, an unacceptable observed.

SEISMIC RELIABILITY ASSESSMENT OF OPTIMALLY DESIGNED STEEL CONCENTIRCALLY BRACED FRAMES
The main aim of this study, is to evaluate the seismic reliability of steel concentrically braced frame (SCBF) structures optimally designed in the context of performance-based design. The Monte Carlo simulation (MCS) method and neural network (NN) techniques were utilized to conduct the reliability analysis of the optimally designed SCBFs. Multi-layer perceptron (MLP) trained by back propagati...
متن کاملA Comparison of Seismic Safety of Steel MRF Designed According to Different Editions of Iranian Seismic Code
In this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the Iranian code of Practice for seismic resistant design of buildings. Also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. First, the testing cases were design...
متن کاملProbabilistic assessment of the seismic damage in reinforced concrete buildings
The main objective of this article is to assess the expected seismic damage in reinforced concrete buildings from a probabilistic point of view by using Monte Carlo simulation. To do that, the seismic behavior of the building is studied by using random capacity obtained by considering the mechanical properties of the materials as random variables. Starting from the capacity curves, one can obta...

Based on the experimental study for seismic performance of FRP reinforced concrete beam-column joints, two-storey two-span plane frames were taken for examples, in which the static elastoplastic analysis (the pushover method) was carried on the joints of the FRP strengthened concrete frames, and then the comparative analysis was made on seismic performance of RFP strengthened frame structure th...
متن کاملSeismic Response of Reinforced Concrete Columns
There are a large number of reinforced concrete buildings in seismically active areas of the world that are not built in accordance with modern seismic design provisions such as those published by American Concrete Institution ([ACI] Committee 318, 2008). In the United States and other parts of the developed world, these buildings were constructed between 1930s to mid 1970s according to the bui...
