Development of seismic fragility surfaces for reinforced concrete buildings by means of nonlinear time-history analysis

Probabilistic 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...

A SENSITIVITY ANALYSIS FOR ENHANCING IDA EFFICIENCY IN FRAGILITY ANALYSIS OF 3D REINFORCED CONCRETE FRAMES

Due to several uncertainties  which  affect structural responses of Reinforced concrete (RC) frames,  it is sensibly required  to  apply  a vulnerability analysis tool such as fragility curve. To  construct an analytical fragility curve, the incremental dynamic analysis (IDA) method has been extensively used as an applicable seismic analysis too...

Time-dependent Seismic Fragility Curves on Optimal Retrofitting of Neutralized Reinforced Concrete Bridges

Simulation of Nonlinear Seismic Response of Reinforced Concrete Structural Walls

In this study the performance of three macro-models in predicting the nonlinear response of different walls is investigated. The macro-models used are: Equivalent Beam Model, Multiple Vertical Line Element Model and a shear panel model developed by Massone et al. (2006). The walls are classified as slender, intermediate, and squat walls according to their shear-span ratio. First, three single w...

A methodology for Determining the Seismic Vulnerability of Old Concrete Highway Bridges by Using Fragility Curves

Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...
