Design of Composite Joint with Precast Bolted Shear Connectors for The Fabricated Structure

Because of the serious impact on the seismic performance, the joint connection form becomes a critical problem in the prefabricated building. Built on the dry connection, this paper proposes a detachable and recyclable bolt-steel plate connection design for the fabricated structure. Compared to the cast-in-situ method, the biggest advantage of the proposed design scheme lies in convenient construction. The construction process shows that the joint devices both are detachable and recyclable. Adopting a supported beam, the proposed form is simulated with the finite element method (FEM). The deformation results verify the effectiveness of the proposed connection design. The work provides a novel idea for further test research on the fabricated structure.
