CROSS-SECTION’S SELECTION OPTIMIZATION OF CENTRAL COMPRESSED METAL STAND FROM ROLLED ASSORTMENT
Keywords:
steel structures, central compression, metal stand, the composite section, material utilization ratioAbstract
In this article an calculating algorithm for central compressed steel stand of complex section for various forms of rolling mix, by taking into account the building code DBN V.2.6-163: 2010 "Steel structures" requirements as defined by the buckling coefficient φ are shown. Comparison of the basic geometrical characteristics for different types of complex steel stand’s cross-section, namely the double-T, channel iron, closed rectangular, tubular cross-section and equal-leg angles is shown. From the equal area material using point of view is shown, that tubular circular cross section is effective. At the same time, from an economic point of view, up to day the cheaper is comlex cross-section of equal-leg angles.
