Stress-Strain State of Framed Pipe-Concrete Assemblies of Bent-Welded Profiles
Abstract: The article provides an analysis of the work of frame pipe-concrete (TB) units from bent-welded closed profiles (GSP). The selection of the required sections of the GSP and the characteristics of concrete was carried out, taking into account the existing methods for calculating pipe concrete, the current regulatory documents and future experimental studies of real models of TB nodes. A finite element (FE) model of a frame node of a multi-storey frame building was created in the LIRA-SAPR software package using GSP. The finite element method (FEM) was used to numerically calculate the TB of a node in order to identify the patterns of operation of a steel-reinforced concrete frame structure under load. The conclusions on the bearing and deformation capacity of the investigated structure in the place of joining the ledgers (cantilevers) to the TB post have been made. The bearing capacity of the frame TB unit made of GSP according to the first group of limiting conditions is determined.
Keywords: pipe-concrete unit, bent-welded closed profile, finite element method, numerical calculation, load, stress-strain state (SSS), load-bearing capacity.
