Introduction In recent years functionally graded materials (FGMs) have attracted much attention from engineers and researchers due to their unique thermomechanical performance [1,2].

Nowadays civil engineers put forward higher requirements of sophisticated and visual analysis of structure.
The calculation to internal force extremum in the control section is the problem that has always been concerned by structural engineers and not well resolved in the SSEB field.
And it provides a new method for the engineering design researchers used entity model calculation of live load effect
