BACKGROUND Fracture risk assessment tools are useful to calculate the long term probability of osteoporotic fracture. However, how it reflects bone quality is unknown. The aim of this study was to correlate the WHO clinical fracture risk assessment tool, FRAX, with bone mechanical properties. METHODS Six patients submitted to hip replacement surgery, either due to osteoporotic fractures or to...

A combination of a deterministic approach and fragility analysis is applied to assess tsunami damage caused to buildings. The area selected to validate the model is Imwon Port in Korea. The deterministic approach includes numerical modeling of tsunami propagation in the East Sea following an earthquake on the western coast of Japan. The model is based on the linear shallow-water equations (LSWE...

This paper proposes a probabilistic formulation to assess the effectiveness of the fiber reinforced polymer (FRP) retrofit schemes in enhancing the structural performance of reinforced concrete (RC) bridge columns. Two probabilistic models are proposed to predict the deformation capacities of retrofitted columns. One deformation model corresponds to the flexural failure and the other considers ...

Quantification in seismic probabilistic safety assessment (PSA) includes the convolution of hazard and fragility curves. Because it is difficult to find closed-form integration for two curves, numerical methods are widely used practice. In practical applications, number ground motion level bins limited, not clear whether limited leads conservative or optimistic results. this study, effect on qu...

A probabilistic method was developed for ranking Canadian hydropower dams according to their seismic vulnerability. The method is based on the probabilistic seismic hazard at the dam location, the seismic fragility of the dam, and the construction date of the dam. The seismic hazard is represented by the peak ground acceleration of seismic motions at the dam location for a specified probability...

of bridges are typically based on simplified analyses or empirical data from recent earthquakes. Since earthquake damage data are very scarce in the central and southeastern United States (CSUS), using analytical methods is the only feasible approach to obtain fragility curves. In 1990, bridges in the CSUS began incorporating seismic details. Some of the changes included the component design fo...

In active seismic zones, such as the Peruvian coast, tools for predicting potential negative impacts of earthquakes are essential planning mitigation, emergency, and recovery transportation facilities. For instance, capacity a road bridge network after event to carry traffic flow depends on degree expected damage related repair costs downtime. This paper determines vulnerability highway bridges...

Prior to the enforcement of seismic details, older-type fully encased steel-reinforced concrete composite (SCR) columns were utilized in many buildings and bridges constructed active regions worldwide. However, there is serious lack knowledge literature about behavior older buildings’ SRC with non-seismic details. Shear strength expressions, stiffness, backbone curves, nonlinear modeling parame...
