Abstract
Heavy industrial building is mainly used in heavy machinery, electric power, metallurgy, petrochemical, shipbuilding, aerospace and other core areas relating to national heavy industry facilities. It has characteristics of large span, high pillar structure, large vertical column width, big crane lifting weight and high using frequency, this kind of plant is more used in lattice structure and truss, in order to use less material to burden larger load. The research background of this article is a steelmaking plant of Baotou, in the metallurgical smelting workshop, temperature is higher because it is directly affected by intermittent thermal radiation, this kind of heavy industry workshop has a higher requirement on the column, choosing the right bar is particularly important, which should achieve the best balance between reliability and economy. In this paper, it takes seven-span monolayer steel structure plant with heavy duty crane as the research object, using the STPJ module in PKPM to design, according to the design condition of the plant and the current design codes, choosing concrete filled steel tube lattice column and steel tube lattice column to design and analyze for the workshop, finally to choose the most suitable cross section of the column for the project. First the lattice concrete filled steel tube column is selected in this article, analysis of plant engineering background and the technical conditions of STPJ are conducted, on the premise of meeting the design specification to calculate the load preliminarily, calculate the structure in horizontal earthquake, wind load and crane load, in order to meet the requirements of normal use. To calculate the internal force of the column section after optimization, comparison of the combination of internal force and choose the control internal force, and with the E axis as an example, according to the Specification for Design And Construction of Concrete—filled Steel Tubular Structures to check the structure in strength, rigidity and stability, etc. Using the second solution, the factory chooses steel lattice column and under the same project condition applying STPJ module to calculate the load preliminarily, calculate the
