Tensioning integral structure is a new type of structure composed of continuous cables and intermittent compression bars. Research on cylindrical and spherical tensioned monolithic structures has been widely carried out, but another basic geometric topology form - circular tensioned monolithic structures - has received little attention. Propose a new type of ring tensioned integral structure, study its topology and shape finding problems, and use the balance matrix method to solve the self stress mode and mechanism displacement mode of the structure. A new type of cable dome is proposed by introducing a circular tensioned integral ring beam into the cable dome structure, and the initial prestress distribution and structural performance are analyzed. The calculation results show that the new cable dome is a tensioned integral structure with good stiffness and complete self-supporting and self balancing. This study enriches the existing forms of tensioned integral structures and their applications
