Abstract: In this paper, strain distribution properties of the shear panels under cyclic loading tests are investigated based on image processing techniques. The high precision measurement by the image processing system is confirmed by comparing with the measured value by strain gauges. Various shapes are tested and their strain distributions in the panels are obtained. The stress concentration is observed at the corners of the square panels, whereas a square panel with round flares at four corners show a moderate stress distribution. No stress concentration appears in the panels with vertical stiffeners at both sides. The relationship between shear load - displacement and stress distribution in the panel is unveiled.
