Research of section optimization design of steel structure main workshop of a large thermal power plant

Abstract

In order to reduce the section size of column C and D column, to satisfy the needs of process engineering, this paper, by using the finite element analysis software STAAD model the stress of the main building, the main steel structure building carried on the thorough analysis, put forward two kinds of section optimization scheme, the comparative analysis shows: in the same section and the amount of steel case, the safety of the second scheme is higher than plan a, therefore, the scheme two is better than one. For scheme 1 and scheme 2, the safety of scheme 2 is 13.7% and 9.8% higher than that of scheme 1 when the same column section, the same load and the same parameters are used for column C and column D. The research results are applied to Hami Power Plant of State Grid Energy, with only columns C and D, and the actual value saves more than 500 tons of steel compared with the original value, and obtains good economic effect.
