摘要：Closed section steel-concrete structures are becoming increasingly popular in the construction industry as thistype of structures possess various advantages compared toconventional structures. Composite structures usually havesmaller cross-sections than the reinforced concrete structures and thus are more aesthetic. Smaller cross-sectionsalso mean that additional space inside of the building issaved. Furthermore, steel-concrete structures have a higherfire resistance and stiffness than the regular steel structures.Steel profiles also serve a role of a formwork for the concrete. Thus, a relatively fast construction of the steel-concrete structures is ensured.
