A lot of energy is released during an earthquake. For a building with certain input energy, the demand on energy dissipation through inelastic deformation can be eliminated by using structural protective systems. As a result of this approach, the building consists of several rigid parts connected by highly dissipative structural fuses. IIn In this study, a 5 storey building with a simple floor plan is taken into consideration. The building is assumed to have a soft story in the ground floor and 4 stories on top. It is considered in two versions: First as conventional wall bearing masonry, second as a HYDE system with a seismic link in the ground floor. Wall openings comply with EC8 regulations. Each structure is modeled with linear shell elements and non-linear hysteretic spring elements are used to model the HYDEs in the seismic links. Crack development in corners of openings is checked by fracture mechanics principles. Non-linear time history analysis is performed with adequate earthquake records (e.g. a Central Asia Earthquake). This study presents relations between force, local stresses, crack development, energy dissipation and maximum top displacement. The results demonstrate again the superior performance and economy of a HYDE system and its capacity to protect wall bearing masonry structures against earthquakes.
