The purpose of this paper is to investigate a dissipative reinforced concrete structural wall that can improve the behavior of a tall multi-storey building, evaluating the damage it undergoes in comparison with that of a solid wall. The comparative nonlinear dynamic analysis between a dissipative and a solid wall is performed by means of SAP2000 software and using a layered model. The solution to increase the seismic performance of a reinforced concrete structural wall is to create a slit zone with short connections. These are introduced as a link element with multi-linear pivot hysteretic plasticity behavior. The behavior of these short connections is modeled using the finite element software ANSYS 12. The authors propose to evaluate the damage of reinforced concrete slit walls with short connections using seismic analysis. Using the proposed computational model, a seismic analysis of the dissipative wall belonging to a multi-storey building was performed. From the results obtained, the advantages of the proposed model are observed. The proposed computational model consumes low processing resources and reduces the processing time for a dynamic pushover analysis. Unlike other studies on slit walls with short connections, which are focussed mostly on the nonlinear dynamic behavior of the short connections, in this paper the authors take into consideration the whole structural system, wall and connections.
