Abstract
Reinforced structures made of cellular concrete began to be used relatively recently. Broad experimental data for the development of calculation methods, in contrast to the calculation of structures made of conventional reinforced concrete, used as load-bearing flexural elements, is currently insufficient. However, the acquired experience in the construction and research of the strength and deformability of reinforced structures allows developing practical methods for calculating and designing structures made of cellular concrete. The existing design provisions should be clarified both in terms of checking the boundary values of the design values, and studying them on various types of cellular concrete, which in turn have a wide range of strengths, volume weights and elastic characteristics. The authors consider the nature of the “stress–strain” curve for cellular concrete, and also carry out a calculated and experimental assessment of the breaking moment of foam concrete samples in the framework of a calculated and experimental study of the strength and deformability of flexural elements made of cellular concrete. The refinement of the calculation of the strength of the flexural elements showed a high convergence of the calculated values of the breaking moment and the experimental data, which allows using the calculation made by the authors for the design of structures made of cellular concrete of various physical and mechanical characteristics.
