SERVICEABILITY  OF  REINFORCED  CONCRETE  FRAME  WITH  JOINT  DEFECTS  OF  COLUMNS

The paper presents results of diagnosis and evaluation of reinforced concrete frame structures of OOO ‘Tomskneftekhim’ which have joint defects of columns. Methods of serviceability restoration of frame structures are suggested in this paper. Results of static analysis of structures simulated by the finite elements method using the software package SCAD are described in this paper taking into account the geometry and physical characteristics of structures. Methods of strengthening structures with joint defects of columns are suggested herein.

Keywords: reinforced concrete frame; ground-penetrating radar; reliability; static analysis; joint strengthening.
