Theoretical Analysis and Model Experimental Research on Single-Layer Hyperbolic Paraboloid Latticed Shell

Abstract:

Single-layer hyperbolic paraboloidal latticed shell dome is adopted in the gymnasium of China University of Petroleum. And the center part of the dome employs crossed web bars in order to increase stiffness of the structure. The 1:12 scale model has been made according to the construction drawings, and the mechanical properties of the model are studied under self-weight load and design load. The regularity of the members' axial force and joints' displacements are obtained. And the results show that the deflection of dome under design load conforms to the requirement of specifications, which verified the correctness of the structure design. It is found that there is no overall instability and local instability, and the behavior of the structure is almost linear.
