Investigation of thermal stresses in the I beams with circular holes in the web

An experimental investigation of transient thermal stresses in the I beams with circular holes in the web is described. The experiments were performed using four photoelastic models of the I beams made of epoxy resin. The experiments reported in this paper included two-dimensional photothermoelastic analysis, measurements of thermal strains and transient temperature distributions. The results of experimental investigations enabled Authors to propose the computational FEM model for the analysis of transient thermal stresses in the webs of the I beams models.
