Abstract: We designed the experimental model of main tower of Tianjin Haihe bridge according to photoelastic experiment theory and proceeded stress experiment at the positions where the stress calculation is precise. Then we compared the experimental results with the finite element calculation results to verify whether the photoelastic experiment fits the stress calculation of main tower of cable-stayed bridge. The experimental results show that the photoelastic experiment could supply gist for the stress calculation of main tower of cable-stayed bridge, which is significant far and wide.

Abstract: The distributions of stress intensity factor KI and KII in notched beam specimens have been obtained in this paper by researching on internal force distributions, photoelastic experiments and statistics from numerical results. Two approximate formulae of KI and KII have been constructed. A simple and correct way to calculate KI and KII of beam is provided.
