A new experiment equipment of measuring stress for homogeneous curved beams and composite curved beams is developed. This achievement of scientific research will be applied to educational experiment. Problems in engineering structures are introduced in the new experiment. Hence, it provides with an opportunity for students to improve their practical ability. The differences of curved beams, composite curved beams and straight beams can be found in the experiment. The present equipment can be used to measure the normal and shear stresses in simply supported curved beam made of steel and composite curved beam of steel and copper with trapezoid cross sections. The concentrated force is applied at the arch top of the curved beams. Good agreement between the experiment measurements and theoretical solutions is found.
