In the context of the proposed prefabricated metro station named Yuanjiadian Station for Changchun Metro Line 2 and based on the final purpose of studying the tenon and mortise grouting joint’s mechanical properties, prototype test system of joint was developed and staged test finished. The test system includes loading system, test and monitoring system, assembling and grouting system, lifting and installation system and so forth. The system can complete the fourpoint bending test and four-point shearing test under any axial force of the prototype joint. Afterward, destructive test of axial force combining with bending moment was carried out under different conditions (including grouting ranges, grouting materials and tenon lengths). Ultimately, the flexural capacity and flexural rigidity for some specific tenon and mortise joint was derived and the safe bending moment of the joint was shown, providing guidance for design and construction.

Keywords: Flexural rigidity, prototype test, test system, ultimate flexural capacity.
