Finite-element model of columns and floor connection and analysis of them

UDK: 624.04

V. I. Sykulev, M. P. Son

The article considers three ways of modeling the columns and floor connection in-situ reinforced concrete buildings. The first model is linear finite element that has a common node with shell of floor slab. In the second model connection is carried by dint of absolutely rigid element. In the third model, columns modeled by dint of volume element. Calculation of all models was done using the software package Lira SAPR 2015. Calculation of all models was done using decreasing meshes: 1000, 500, 200, 150 mm. The results of calculations were supporting and interjacent moments in the floor slab. On the basis of the numerical experiment was performed analysis of calculation results - was performed analysis the impact of the selected method on the convergence of the results, were selected possible reasons for the difference between the results.
