Seismic Retrofit of Vulnerable Steel Frames Using Articulated Quadrilateral bracing system [PDF]
This paper investigates the applicabilty of an innovative bracing, called Articulated Quadrilateral (AQ) bracing system, which uses shape memory alloys (SMAs), for retroffiting low-rise to high-rise vulnerable SMFRs against strong ground motions.

Mainshock-Integrated Aftershock Vulnerability Assessment of Bridge Structures
Seismic fragility analysis is often conducted to quantify the vulnerability of civil structures under earthquake excitation. In recent years, besides mainshocks, strong aftershocks have been often witnessed to induce structural damage to engineered ...

Failure Probability Evaluations of a Wind Turbine Under Earthquakes and Wind Loads
Comparative evaluations of failure probability were conducted with respect to an in-service wind turbine under earthquakes and wind loads. Firstly, to obtain the hazard curves under earthquakes and wind loads for a specific region where the wind turbine ...

Graphic Analysis of Osmotic Fragility of Erythrocytes
A precise and highly reproducible method for analyzing the osmotic fragility of erythrocytes with a minute amount of blood (less than 10 mul) is described. The osmotic fragility curves are recorded with a coil planet centrifuge with accessories and a scanning photodensitometer.

Influences of site conditions and ground-motion frequency characteristics on structural fragility
Site conditions and ground-motion frequency characteristics play a significant role in structural response and seismic damage distribution. However, the current structure fragility analysis techniques have hardly considered such effects. Taking the ratio
