The creation of the efficient reinforced concrete structures, that allows to reduce the material consumption as well as the labor costs, is the most important task today. One of the possible ways of solving this problem is the design and wide application of multilayer structures in which high mechanical, heat engineering and acoustic properties are provided due to the combination of high strength of heavy concrete and low strength of light concrete with low heat conductivity. The advantages of three-layer reinforced concrete structures are shown. The proposals have been made to take into account the sag and the classes of lightweight concrete of such elements.

Introduction. The present study is targeting the problem of choosing construction solutions for strengthening the frame of a reconstructed multi-storey administrative building. The object of the study is the former Council of Ministers building in the town of Sukhum, Republic of Abkhazia.Materials and methods. During the examination of the building under study, instrumental and visual inspection methods were implemented, which revealed the significant deflection of the roof slab and of two supporting steel beams, as well as emergence of cracks in the load bearing structures and the destruction of partitions. According to the results of examination the dimensional-planning drawings and a structures’ defects list were elaborated. A spatial finite element model of the building was developed in the LIRA-SAPR software package, taking into account the developed dimensionalplanning solutions for the reconstruction of the facility under study. Loads and impacts were set taking into account the requirements of relevant design standards. The detected defects of the structures’ elements were considered.Results. The dynamic calculation of the building frame by finite element method is carried out. The calculation results analysis has shown that all three forms of oscillations are torsional, which proves the structural solutions of the building frame to be complex and requires additional calculations to ensure reliability of construction solutions. The building frame dynamic loads are set taking into account the requirements for buildings with a complex structure frame. The results of the general static calculation has shown that the load-bearing structures of a building are in operating state except for the roof slab.Discussion and Conclusions. Based on the results of a numerical experiment on modeling the operation of the roof slab, the rational solutions for its reconstruction have been developed, recommendations on considering the seismic impacts on the reconstructed building frame of the Council of Ministers have been given.
