To the determination of the stress-strain state of a concrete block as part of a reinforced node truss from bent-welded profiles


Author(s): Gimranov Linur Rafailevich and Pazhwak Abdurahman

Abstract: Problem Statement: This article discusses analytical and numerical studies to determine the stress-strain state (SSS) of a concrete or fiber-reinforced concrete block in a truss node from bend-welded profiles (BWP). At the same time, a distinctive feature is that the nodes are strengthened locally. Problems are solved to determine stresses in a fiber-reinforced concrete element for a common section with a vertical axis of symmetry, taking into account the linear relationship between a concentrated load and stress in a fiber-reinforced concrete block.
Purpose: The purpose of the work is to develop on the basis of idealized design schemes of a fiber-reinforced concrete block of analytical dependencies to determine its stress-strain state, under a concentrated load, with a sufficient degree of reliability reflecting the stress-strain state of a block inside a loaded node from BWP profiles.
Results: The main results of the work consist in the analytical study of nodes from the BWP of a fiber-reinforced concrete block and the determination of its stress-strain state (fiber-reinforced concrete block) based on the results of calculation in the ANSYS Workbench software package.
Conclusions: The significance of the obtained results for the construction industry lies in the fact that using the method of sections, it is possible to calculate the node. At the same time, a fiber-reinforced concrete block is cut, the section is considered and equilibrium conditions are created for the cut-off part of the block, taking into account the bending moment, the calculation of normal stresses is performed. The results obtained from numerical studies using the Ansys program for truss nodes show that it is close to the results of the operation of a fiber-reinforced concrete block in locally reinforced truss nodes from BWP.
