Effect of additional grid installation on the stress-strain state of a three-hinged arch

[摘要] The authors of the article have analyzed the stress-strain state and design of a new rational circular tie-arch. In the article the arch stress-strain analysis of symmetric and asymmetric loads and the comparison of the new design with the classical one are studied. The most rational position of the struts of the new arch is established by varying their geometric parameters. The calculation of arches is performed taking into account the compliance of joints, and consumption of building materials for the production of structures is determined. As a result of research it is established that the use of a new design of the arch allows to reduce the bending moment in the top chord that results in the general decrease in consumption of wood for the production of an arch.
