The calculation model in which the cross-section of three-layer structure is substituted by I-beam homogeneous section of imaginary higher strength concrete is selected. The executed analysis have verified the possibility to use the I-beam transformed section model even for the calculation of three-layer composite reinforce concrete structural elements.
