Intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. It is a kind of high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating to play a role of rust freeThe bearing capacity of decorative stainless steel pipe ice load is the main control load of offshore platform in severe cold area, which has high requirements for the shear bearing capacity of jacket leg of offshore platform. In order to study the factors affecting the shear capacity of the jacket legs of the stainless steel pipe in pipe concrete-filled steel tubular offshore platform, a total of concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material, concrete strength, void ratio and shear span ratio on the shear capacity of concrete-filled steel tubular in pipe. It is found that the shear strength of members increases with the decrease of void ratio and the increase of concrete strength; The larger the shear span ratio, the smaller the shear strength. Combined with the test, the empirical formula of shear capacity of concrete-filled steel tubular in pipe is proposed, which is analyzed and verified by ABAQUS finite element modeling software. The results show that the simulation is in good agreement with the test results. In order to study the axial compression performance of stainless steel tube concrete conduit leg and the axial compression performance of stainless steel concrete conduit leg, experiments are used to verify the correctness of the finite element model. The load displacement curves of specimens in groups were compared, and the effects of different void ratio concrete strength, diameter thickness ratio and bone index on the axial compression performance of concrete-filled stainless steel tubular short columns under axial compression were analyzed. The results show that with the increase of concrete strength, the bearing capacity of specimens increases, but the ductility of specimens decreases; With the increase of void ratio and diameter thickness ratio, the bearing capacity of the specimen decreases; The bearing capacity of stainless steel tube concrete can be effectively improved by adding steel bone; Increasing the bone matching index of steel bone can improve the bearing capacity of the specimen.
