Up till now,numerous earthquakes that occurred worldwide have proved that the quake-breeding physical model of destructive earthquakes may repeat and reappear.

In this paper, the main parameters of poison gas s numerical simulation are analyzed on the basis of studying of the numerical simulation and dynamic emulation of poison gas leakage and diffusion possibly occurring in the destructive earthquake.

In this paper, the numerical simulation and dynamic emulation of poison gas leakage and diffusion that possibly occur in the destructive earthquake are studied.

Investigation on seismic vulnerability of vertical storage tanks based on probability estimate method

At first,the steps of seismic hazard analysis of damsites are expounded, then an analytical method is put forward of seismic vulnerability of dams according to their types,and finally five earthquake damage grade levels of dams subjected to earthquake loads are described.

Numerical simulation analysis on the seismic fragility of storage-tank

, seismic hazard analysis, seismic fragility analysis and seismic loss assessment.

However,this study verifies the consistency of the two formulations via the analytical derivation of the seismic fragility function,in which some important relationships are found.
