Suspended-dome structure capable of arranging prestressed hoop cables in blocks

The invention discloses a suspended-dome structure capable of arranging prestressed hoop cables in blocks. The suspended-dome structure comprises an upper reticulated shell which is supported by at least two independent cable support units which are arranged in blocks, and each independent cable support unit is formed by mutually connecting at least two rings of the prestressed hoop cables, multiple prestressed diameter cables and multiple support rods. According to the suspended-dome structure, the upper reticulated shell is supported by the independent cable support units which are arranged in blocks, sudden changes of the internal force of the prestressed hoop cables of an irregular-shaped suspended dome can be avoided while the requirements of the suspended dome for architectural modeling are met, the requirement of a roof structure for architectural modeling can be met, distribution of the internal force in the hoop cables can be uniformed, the prestress loss on the prestress hoop cables can be reduced, and the stressed performance of the structure can be improved. In addition, the suspended-dome structure is simple and beautiful in modeling and enhances the aesthetics of a building.
