Abstract
The hybrid grid shell, made of quadrangular meshes diagonally stiffened by pre-tensioned thin cables, is an attractive structural form in the design and construction of long-span transparent glass roof structures. These hybrid structures are very slender and lightweight, and it is desirable to understand their detailed structural behavior. The mechanical characteristic of the hybrid structure was investigated based on a quadrangle of slats with cross cables. The construction of the design model for the glass roof was firstly described. Then, the static behavior and stability capacity of the hybrid grid dome and the corresponding single-layer lattice dome were studied based on a finite element model. Moreover, the modal analyses of the two domes were carried out. The natural frequencies and the vibration modes of the domes were given to investigate the dynamic behavior of the hybrid grid dome. Finally, the effects of the asymmetric loads and rise-to-span ratios on the structural behavior were studied in detail.
