The Design of a Timber-Metal Arch with an Additional Lattice Taking Ductility of Nodal Joints into Account

Abstract

The article is dedicated to the rational efficient design of a threehinged arched coating. It is noted that as a result of a significant decrease in the bending moment under asymmetric snow load, the structure possesses a good rate of basic materials consumption. The numerical analysis of the arch stressstrain state has been done. The results of the arch stress-strain state under asymmetric and symmetric loads, including comparison with the stress-strain state of a classical three-hinged arch, have been given.
