The seismic behaviour of precast concrete modular constructions depends highly on the connections between structural elements, particularly those located in the horizontal joints in wall-based structural systems. Several dry and wet connection solutions have been developed in recent years, but most of them require complex assembly processes and additional concrete casting or were not designed to be seismic-resistant. Also, the possibility of having easy access to connection replacement in the case of seismic damage needs to be considered. The paper presents the design conception, detailing and testing of four types of a dry connection for horizontal joints between insulated bearing walls. The behaviour of the connection is investigated through a testing campaign of full-scale specimens subjected to tensile axial monotonic tests and tensile cyclic loading tests. The results are discussed in terms of force-displacement curves, tensile capacities and failure modes. The results showed a promising strength and deformation capacity when adequate detailing near the connection is ensured.
