摘要：Problem statement. The use of timber in multi-storey buildings is a promising direction in terms of reducing the impact of the construction industry on the environment. Hybrid buildings represent a rational combination of timber as the main structural material and reinforced concrete for spatial stability providing. At present time there are no recommendations for the choice of structural system of multi-storey hybrid buildings, the issues of joint work and stressstrain state of load-bearing structures of timber and reinforced concrete in the spatial system of multi-storey buildings are insufficiently studied. The article is devoted to the analysis of the stress-strain state of hybrid timber-reinforced concrete multi-storey buildings. In the study, the number of storeys of the building was accepted of 5, 10 and 15 floors. The type of the joints between of the load-bearing structures and the method of ensuring spatial rigidity, namely the number and location of the shear walls and the rigidity core, were varied. For each option, a spatial finite element model was compiled and a static load analysis was performed in accordance with the requirements of current design standards. Results and conclusion. The data on the magnitude of the horizontal displacements of the upper part of the building, as well as the maximum values of the forces from adverse combinations of loads, were obtained. The analysis of the stability of the building and the bearing capacity of timber columns were performed. Based on the results obtained, the recommendations are proposed for choosing a structural scheme, a method for ensuring the spatial rigidity of a building, as well as assigning cross-sectional dimensions at the initial stage of the design of a hybrid timber-reinforced concrete multi-storey building.
