Structural System and Conceptual Model Test of Solar Chimney
The solar chimney power station is a renewable energy system consisting of solar collector, wind turbine, and chimney. To improve the efficiency of energy generation, the higher chimney is the better. Considering the difference between the solar chimney and the traditional high-rise structure, the study on the chimney from the structural point of view is produced in this paper. The existing and planed chimneys are first introduced. Then the solar chimney is classified according to material, structural system, and constraint condition. Followed that, application of prestress technology including adoption of prestressed concrete, introduction of circumferential prestress, arrangement of stayed cable or cable net, and utilization of tensegrity system in the solar chimney is involved, which can improve the structural behavior of the chimney significantly. On this basis, conceptual models of three different structural systems are designed, and the performance of the models is tested under the horizontal force to show the effect of stayed cable and spokewise cable.
