【 摘 要 】

The reliability evaluation of the stochastic seismic responses of the large span isolated structure is studied based on the probability density evolution and extreme distribution theory. The method can accurately give the probability density and probability distribution of structural displacement extreme. According to the deformation limit, the dynamic reliability of each layer and roof can be obtained directly, and it's a feasible approach to the precise reliability analysis of large span isolated structures. The calculation results show that for the isolation layer is the most vulnerable part, and the grid roof takes second place, while the superstructure is relatively safe. The isolation layer and the grid roof should be enhanced in the design of large span isolated structures.
