The calculation, modeling and experimental research of steel-concrete tubular elements made of thin-walled galvanized sheet metal and
lightweight concrete have been carried out. The proposed type of structures can be used as a separate structure in the form of a column or
a pillar, and one of the types of the reinforcement of a certain light structure. The basic technological and constructive requirements for
manufacturing and further exploitation of structures are given. For determination of actual work’s indexes of constructions experimental
research of standards are undertaken, and recommendations on adjustment of well-known calculation formulas of close constructions as
for structural parameters are given. The design (modeling) was performed in MSC / Nastran software. An analysis of the proposed structures use is carried out with the corresponding conclusions.
