The invention belongs to the field of airplane structural strength tests, and particularly relates to a test device for a typical structure of a composite T-shaped stiffened wallboard. The testing device comprises a base (3), a top block (4) and two supporting blocks (5), the base (3) comprises a bottom plate and two side plates oppositely arranged on the bottom plate, the top block (4) and the supporting blocks (5) are located between the two side plates, and a rib test piece (13) is located in a gap between the top block (4) and the supporting blocks (5); an adjusting screw (6) is arranged on a side plate of the base (3) to drive the top block (4) and the two supporting blocks (5) to clamp a rib test piece (13), the base (3) is arranged on the mounting disc (2), and the position of the base (3) is adjusted through a longitudinal adjusting block (8) and a transverse adjusting block (9) on the mounting disc (2). According to the invention, typical structure tests of T-shaped stiffened wallboards with differen
