Summary Hybrid structures which consist of membrane, cable members and rigid structures are experimentally studied in the paper. The experimental modal,with the scale of 1/2,is a roof structure of a planned house. The hybrid roof structure consists of a rigid structure and eight rods. By introducing pre-stress into the rods,the roof structure is stabilized. The roof is covered with membrane, and pre-stress is also introduced into the membrane. In the first part of the paper, the experiment for introducing pre-stress in the rods and membrane is investigated. By measuring the strain, the self-equilibrated stresses of the rods are obtained. In the second part of the paper,load is applied to the hybrid structure with the total weigh of 650kg. The displacement of the rigid structure and the stresses of the rods are measured. In the third part of the paper, the strain in the membrane is obtained by measuring the distances of two points on the membrane surface to check the stress in the membrane. The pre-stress introduced in the membrane is about 200kg/m. In the paper, the experimental results are compared with analytical results by the method proposed by the authors, and the validity of the analytical method is shown.
