Experimental study of wind impact on multilevel industrial scaffolding

Abstract

In the article, the local stress-strain state of structures and constructions is investigated, various variants for the design of the boundary are taken into account: special lines, points. The acting forced deformations don’t satisfy the compatibility conditions. They have a finite discontinuity along the contact line (surface) of the domains, including the irregular point of the boundary, causing stresses. The subject of article is stress concentrators the singularity of the stress-strain state of structures and constructions exhibiting “constructive heterogeneity” and discontinuous forced deformations determined on polymer models of photoelasticity and defrosting of deformations. A complex theoretical-numerical-experimental approach, for obtaining and analyzing the stress state in the neighborhood of the irregular point of the plane domain boundary, is proposed to extrapolate reliable experimental data to a domain where the fringe contour is not readable.

“…Based on Fx, Fy values, the resulting R force is plotted in the XOY plane [31][32][33]. Based on R force in XOY, and Fz component, a resulting force in the load cell mounting area is plotted.…”

“…Based on R force in XOY, and Fz component, a resulting force in the load cell mounting area is plotted. These forces are analyzed in detail in papers [31][32][33].…”

“…Figures 12 and 13 show values and directions of forces of Fx, Fy in the aeroelastic model in the XOY plane for the angles of wind flow attack equaling 00 and 1350, respectively, and for an open aeroelastic model (Option (0000)). Based on Fx, Fy values, the resulting R force is plotted in the XOY plane [31][32][33]. Based on R force in XOY, and Fz component, a resulting force in the load cell mounting area is plotted.…”
