The influence of the effects degradation materials on seismic fragility Cultural Heritage buildings in Granada (Spain) is investigated. material, which mainly happens at lower levels façades, obtained by using 3D photogrammetry data. Fragility curves for three cultural heritage constructions are calculated FE nonlinear dynamic analyses both non-deteriorated and deteriorated geometries. Finite E...

The design code Eurocode 7 relies on semi-probabilistic calculation procedures, through utilization of the soil parameters obtained by in situ and laboratory tests, or means transformation models. To reach a prescribed safety margin, inherent parameter variability is accounted for application partial factors to either directly resistance. However, considering several sources geotechnical uncert...

In the scope of a scenario-based risk analysis, this study aims to quantify and rank various types of epistemic uncertainties that enter into the derivation of fragility functions for common buildings. Using a numerical model of a test structure (a reinforced concrete five-story building with infill panels on the first two floors), a first type of uncertainty is introduced, consisting of the me...

Seismic codes were developed to reduce the structural vulnerability and risk associated with earthquakes in earthquake-prone regions of world. The effectiveness code preventing damage is dependent on performance level defined construction technology employed. seismic fragility curves for two recent versions Iran are determined by using hybrid method. probability levels visualized these curves. ...

In this study, an existing hospital structure has been evaluated with incremental dynamic analysis (IDA). This building is accommodated in Karaj with soil type II. At first, two 2-D frames along X, Y direction are selected. Then, five performance levels are determined according to “Rehabilitation Code for Existing Buildings (Publication No. 360) including Immediate Operational (IO), Limited Dam...

This paper presents a probabilistic approach for the design and assessment of structural elements under blast loads. The procedure is based on the broadly adopted fragility analysis method, widely implemented in Performance-Based Design procedures for structures subjected to natural hazards such as earthquake and wind. A discussion on the uncertainties related to blast engineering problems and ...
