To estimate the rigidity of bending reinforced concrete elements based on dependence of length macro trays from load

Abstract

© 2019 IOP Publishing Ltd. All rights reserved. The purpose of this work is to make proposals for calculating the stiffness of normal sections of bending reinforced concrete elements, taking into account the work of the stretched concrete above the macrocrack and stress concentration at its top. In the article, such an account is made by the methods of fracture mechanics using the stress intensity factor KI . One of the stages of calculation consists in the finite-element modeling of macrocracks in ANSYS.
