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

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