Joint schemes are very important in the design of bolted joints in huge composite structures. This article describes the scheme, manufacturing method, performance testing and simulation of a novel bolted joint configuration for top-hat stiffened composite plates. Firstly, a bolted joint scheme is proposed for use in top-hat stiffened composite plates, after which the manufacturing method of the joint scheme is presented, as is the fabrication of test specimens and their bending performance are tested. Then, a numerical method is proposed to analyze the performance of these specimens. Drawing on experimental and simulated results, seven failure modes are summarized with varied geometrical parameter. We change the angle of top clamp ?? and the length of the foam block L
