A partial double-layer reticulated spherical shell
Basic Assumptions
In order to analyze the structure simply, the basic assumptions are presented as follows: The material is regarded as an idealized elastic-plastic model with hardening phrase.
The material model is a bilinear relationship.
At the same time, the geometric and material nonlinearity is considered in the analytical process.

The Simulation Theory of Heat Conduction
The model of three-dimensional heat conduction in homogeneous medium can be briefly expressed as Eq.1:
(1)
In which
T = T(t, x, y, z) is temperature, which is a function of time(t)and spatial variables(x,y,z)
∂T/∂t is the change-rate of temperature
g is the heat generated during unit time by unit volume of heat source
k is thermal conductivity of the material, ρ is the material’s density, Cp is the material’s specific heat capacity.

On the assumption of horizontal layer, there are 15 layers totally in the site, and the material properties of soil site are list in Table 1.
In the calculation, hysteretic damping assumption is used for soil material.
The wall uses linear elastic material model.
