A tent with a reinforced frame-supporting structure is provided, comprising a top disc (1), a plurality of vertex angle support bars (2) whose tops are circumferentially and obliquely connected with the top disc (1), foot bar supports (3) connected with the bottom of each vertex angle support bar (2), hinged beams (4) arranged between two adjacent vertex angle support bars (2), wherein either end of the hinged beams (4) is connected with the upper end of adjacent foot bar supports (3) respectively, a frame-reinforcing support bar (5) is provided between the hinged beam (4) and the top disc (1) whose top is obliquely connected with the top disc (1) and bottom is connected with the middle hinged portion of the hinged beam (4). The tent has the advantages of reinforced-frame structure, increased-hinge stability and prevention of water accumulation in the middle of the inclined plane of the top fabric.
