Problems of Architecture and Construction

Abstract

The article is offering two methods of the determination of the final offsets and time of deformation of flat square-wave paradise, subject to pulsed load, attached to transverse element. The Offsets, achieving approximately one third of a part of the stairwell are determined by method modal approximation and method of the estimation of the borders for offsets; the dependency from plastic velocities of deformation is considered with uniform-viscous defining equations.
