Anwendung von Megaverbundstützen im Anlagenbau

Application of mega composite columns in industrial facilities.

Plant structures in industrial facilities can reach a height of 150 m. The towers are commonly built as a framework structure in steel or concrete. However, as an alternative, the columns of these structures can be built as composite construction. In recent years, the concrete filled steel tubes, i. e. the so-called mega composite columns, have been investigated extensively by HOCHTIEF. In this paper, two types of cross-sections, the rectangular and circular hollow-section, are explained and compared in detail from a static, structural and manufacturing point of view. Moreover, the most significant characteristics in the design and construction of mega composite columns are highlighted within this paper.
