Earthquake-Resisting Rocking Wall System With Floor Interaction

Several recent earthquakes have revealed that most of the buildings designed by modern building codes are able to survive without collapse. However, tremendous economic losses have been encountered due to the permanent damage and residual drift of the buildings. The huge economic losses underscore the need to develop new structural concepts to minimize the damage and the residual drift of buildings after seismic events. The rocking wall system is one of the innovative solutions. Two large-scale rocking wall-slab-column subassemblage specimens were tested in the MAST laboratory at the University of Minnesota successfully from November 2013 to May 2014. Because the two tests only represent two specific cases, numerical simulation is an important part of the project to generalize the results obtained from the tests. Two finite element models will be established using ABAQUS to conduct series of parametric studies. The parameters include two different wall-slab connections, different amount of energy dissipation components, different initial post-tensioned force, different boundary conditions along the edge of the slab, and different column base connections.
