The paper presents aspects of a research performed on a precast hybrid wall model. A full scale hybrid prefabricated wall model was tested to static cyclic loading. The connection was designed for the peak ground acceleration 0.25g and a normalized axial force of 5 %, corresponding to a connection over the base foundation of a shear wall structure of a multistory building. An innovative concept was implemented, by using mild unbounded mild special reinforcement, with guided yielding response. The test revealed a reasonable seismic performance of the proposed concept performance in the terms of load-lateral drift, shear/flexural strength, ductility, energy dissipation, damping and joint opening with load. Despite the lack of bond that usually concentrates the stress in the rebars in the critical sections, the model showed a good seismic capacity. A promising post-collapse behavior should be also noticed.
