THE CALCULATION OF THE STRENGTH OF CONCRETE-FILED STEEL TUBE COLUMNS

Abstract

The calculation of the strength of normal sections of eсcentrically loaded pipe-concrete elements should be used in the structures of high-rise buildings. Nonlinear deformation model of reinforced concrete for three-axis tensely - deformed conditions is accepted for the analytical description of joint work of concrete core and external steel holder.
