Stress-strain state of hybrid timber-reinforced concrete multy-storey buildings considering creep deformation

Abstract

Problem statement. The new solutions of hybrid constructions of multi-storey buildings are being developed, in which the main structural material is timber and reinforced concrete or steel is used to ensure spatial rigidity. The problem in developing such projects is a significant difference in the deformation characteristics and rheological properties of timber and concrete, which can significantly affect the load-bearing capacity and serviceability of the hybrid building. At present time the issues of joint work of these materials in the elements of structural systems are insufficiently studied. The purpose of the article is to investigate the stress-strain state of hybrid wood-reinforced concrete multi-storey buildings taking into account the influence of creep deformations. Conclusion. The method of taking into account the
