Abstract
Light-weight shear wall panels with deterministic cellular periodic architecture could provide the basis for vibration mitigation in large scale structural systems. In this study the behavior of shear walls with cellular solids under seismic loading is examined. An investigation to evaluate the effects of different cellular configurations is conducted, including the orientation angles and the shapes of the cells (honeycomb, re-entrant or chiral architecture). The cellular walls may be appropriately arranged between the columns of a pier of a concrete bridge system for seismic resistance enhancement in both directions. Appropriate simplified Finite Element Models are developed to predict the stiffness, strength, and energy dissipation effectiveness of shear wall panels when subjected to monotonic and cyclic shear loading, with ABAQUS software. The total column-cellular wall-deck system behavior is studied with simple stick models after the calibrated wall properties have been taken into account.
