Bridges are the most critical and usually vulnerable structural component of a road network exposed to various hazards. Damage due recent earthquakes worldwide highlighted substantial direct indirect financial losses related partial or total collapse bridge components pointed need for reliable assessment their seismic performance. This paper presents ‘toolkit’ developed bridge-specific fragilit...

Deterioration parameters that are commonly used to simulate nonlinear behavior of steel components were mainly calibrated based on the results from experiments beams. Recently, state knowledge for deterioration columns has been improved by experimental and analytical studies wide-flange columns. These deteriorating characteristics introduced as regression relationships in which associated uncer...

A seismic fragility curve is a visual representation that illustrates the likelihood of structure surpassing particular damage or performance limit state caused by an earthquake with specific intensity ground motion level. This typically generated using probabilistic hazard analysis and structural reliability methods. It based on statistical models rely past data simulations future scenarios to...

Successful development of the offshore wind energy resource depends upon the reliability of the structures that support the electricity-generating rotor-nacelle assemblies that form the core of a wind turbine system. The risk posed to offshore wind turbines (OWTs) by extreme environmental events such as Atlantic hurricanes requires a more detailed examination of post-elastic structural performa...

In recent ®nancial crises a bubble, in which asset prices rise, is followed by a collapse and widespread default. Bubbles are caused by agency relationships in the banking sector. Investors use money borrowed from banks to invest in risky assets, which are relatively attractive because investors can avoid losses in low payoff states by defaulting on the loan. This risk shifting leads investors ...

The effect of aftershocks on the fragility single-story masonry structures is investigated using probabilistic seismic demand analysis Finite element models an unreinforced (URM) structure and a confined (CM) are established their response characteristics when subjected to mainshock, aftershock, mainshock-aftershock sequence then comparatively investigated. effects use confining members studied...
