Stress Calculation of a Spherical Tank on Settled Ground Based on FEM
In this paper,a model of a LGP spherical tank supported by 8 equator tangent-type supporting on settled ground was built.The stress on the shell,on the pillars and on the connection of pillars with shell were calculated,the stress distribution on shell,pillars and the connection of pillars with shell were obtained,the influence of foundation settlement to the stress of shell and pillars were studied.The results showed that the differential settlement produced a less affect on the shell,but a greater impact on the pillars.The maximum stress arose at the connection between pillars and shell,there is a big stress area in the connectors area.
