Aiming at the areas which are lack of seismic destructional data of bridges,an analytical method to obtain fragility curve of concrete bridges under earthquake is developed considering uncertainties of seismic ground motion,local site condition and parameters of the bridge itself.

While performing a seismic risk analysis, fragility curves are found to be useful tools for predicting the extent of probable damage.

The analysis of structural seismic demand and capacity under different seismic level is the key of the construction of fragility curves.

The analytical methodology for developing seismic fragility curves of highway reinforced concrete bridges;

The comparison between fragility curves from the two methods shows that there is no remarkable difference for concrete spalling damage state,and capacity spectra method underestimates the failure probability of longitudinal reinforcement buckling and collapse for the viaduct structure under given ground .

An analytical method and it s procedures to obtain analytical fragility curves of the major components of reinforced concrete bridges in earthquake is generalized considering uncertainties of seismic ground motion,local site condition and parameters of the bridge itself.

An approach to extension assessment of disaster vulnerability for small towns and its application;

Thinking on causes and tactics to the vulnerability of public environment;

Kill probability contour analysis method for assessing aircraft single hit vulnerability;

The experimental results indicate that the low vulnerability of rocket motor with steel case is low;the fragmentation of the propellant depend on the mechanical performance;and the combustion inten- sity is effected by the thickness along impactiv.

The main properties and low vulnerability tests of 40NTO/60TNT and 25RDX/25NTO/50TNT formulations are researched.
