Abstract. The methodology for drawing of design schemes and strength criteria of composite structures at a special (ultimate) state is presented. The algorithm of the computational analysis of cracking resistance, strength and deformability of precast-monolithic reinforced concrete frameworks of multi-storey buildings made of reinforced concrete panel-frame elements under special (emergency) impacts in the form of a sudden exclusion of one of the structures from the structural system is considered. The stress-strain state of the plane-stressed precast-monolithic crossbars of the frame with a pliable seam of contact between the precast and the monolithic parts is determined using the modified physical model of N. I. Karpenko. The strength criteria for characteristic reinforced concrete elements of unit sizes under the exorbitant states are taken in accordance with the conditions of limiting the ultimate relative deformations of compressed concrete, tensile reinforcement and shear strains in the contact zone of the elements of the composite structure. The results of the computational analysis of the precast-monolithic frame of the building with panel-frame structures are presented in the paper. It is shown that the account of contact zone pliability in composite beams of the precast-monolithic frame significantly affects the deformability of the entire structural system at its dynamic loading and it should be taken in account as an oscillation damper.
Key words: progressive collapse, precast-monolithic frame, reinforced concrete panel-frames, deformation model, strength criteria, special ultimate state. - REFERENCES
