In this paper,an approach of stochastic static analysis of cablestayed bridges including geometrical nonlinearity is presented based on artificial neural network(ANN).

In order to understand the spatial stability behaviors of tilt-basket arch bridge with a considerable small width-to-span ratio,response surface method(RSM) is applied in stochastic static analysis on spatial buckling problem in such a type bridge.

Application of the pseudo-excitation method with spatial coherence in random vibration analysis of long span space structures;

After the vibration of the cab is measured, the vibration theory and Finite Element Analysis are applied to the random vibration analysis of the cab structure of a mining dump truck.

The finite element model of mechanically dithered ring laser gyroscope(RLG) was established, the modal analysis and random vibration analysis about the RLG was performed in the application of the finite element software ANSYS.

According to the related standards,transient dynamic analysis and random vibration spectrum analysis were carried out to get its dynamic response characteristics in vibration and shock environment so as to find out the main weak parts in the structure of electronic cabinet,which provide more convincing evidence for optimization design in cabinet structure.

A new analysis technique,called random wave analysis method,is developed for the random seismic response analysis of layered soil sites under SH wave excitation.

There are three kinds of seismic analysis methods: response spectrum method, time history method and stochastic vibration method.
