effect of asymmetry on the rigid link for random seismic pounding mitigation

Connection of adjacent buildings with stiff links is an efficient approach for seismic pounding mitigation. however, use of highly rigid links might alter the torsional response in asymmetric plans and although this was mentioned in the literature, no quantitative study has been done before to investigate the condition numerically. in this paper, the effect ofrigid linking on elastic lateral-torsional responses of two adjacent one-story column-type buildings has been studied through comparison to unconnected structures. three cases are considered, including two similar asymmetric structures, two adjacent asymmetric structures with different dynamic properties and a symmetric system adjacent to an adjacentsymmetric one.
