A METHODOLOGY OF MODELLING THE STRESS-STRAIN STATE OF RIGID CONNECTION JOINTS OF SITECAST REINFORCED CONCRETE CEILING TO CONCRETE FILLED TUBE COLUMN
The methodology of modeling the stress-strain state of rigid connection joints of sitecast reinforced concrete ceiling to concrete-filled column was developed. The construction of ceiling include the external steel reinforcement plates, which works as ceiling-height beams and steel rigid element, which crosses the concrete filled tube core and allows to transfer the loads from the ceiling on the concrete filled column. The modeling was done with the Femap (NX Nastran) software package, using the geometry models, created in the Autocad graphic environment.
