AbstractAbout AuthorsReferences
The purpose of this work is to propose and substantiate analytical dependences that make it possible to reliably determine the limit axial deformations of the volumetric-compressed concrete core of tube-reinforced concrete elements. Previously published dependences are obtained empirically and therefore have significant limitations in the field of practical application. For example, they are not suitable for the calculation of advanced tube-reinforced concrete elements with pre-compressed concrete. According to the results of comparison with the experimental data, it is concluded that the formula obtained on the basis of the phenomenological approach makes it possible to adequately assess the limit deformations of compressed tube-reinforced concrete elements both with pre-compressed concrete and uncompressed concrete. This formula is universal and can be used for a variety of structures in which the concrete works under the conditions of volumetric compression.
