| Abstract: | The expediency of using precast spun concrete columns and other members of annular cross sections reinforced by high-strength
steel bars is discussed. Test material properties and production, curing and testing procedures, response factors and ultimate
compressive stresses of plain and reinforced spun concrete specimens are presented. The strength and strain features of compressed
tubular reinforced concrete members are considered. Modeling of a bearing capacity of eccentrically loaded members of annular
cross sections is based on the concepts of bending with an concentrical force and compression with a bending moment. The comparison
of modeling and test data of concentrically and eccentrically loaded members is analysed. |
