Although it is recognized that red cells lose membrane during storage, estimation of the osmotic fragility of erythrocytes has not previously proven to be a useful measurement of the storage lesion. Erythrocytes from blood stored in CPD-A2 were found to have a markedly increased osmotic fragility. A major portion of this increase was found to be due to accumulation of lactate, which is only slo...

Fragility curves depict the relationship between a weather variable (wind speed, gust speed, ice accumulation, precipitation rate) and the observed outages for a targeted infrastructure network. This paper describes an empirical study of the county by county distribution of power outages and one minute weather variables during Hurricane Irene with the objective of comparing 1) ‘as built’ fragil...

Seismic safety of liquid storage tanks is of considerable importance due to its application in different industries. In Iran, most of these storage tanks are designed based on API650 code provisions. Despite designing tanks according to API standard, the lesson learned from previous earthquakes, shows different kind of damage occurring on them. This study is an investigation on evaluating diffe...

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...

Abstract Land subsidence has been historically detected and observed using the Global Positioning System (GPS) observations since year 2000. At present, Interferometric Synthetic Aperture Radar (InSAR) method is used to monitor ongoing in Bandung Basin. Due its significant rate, reaching up -20 cm/year, much evidence of impact found this area, e.g., damaged buildings. This study aims develop a ...

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...
