Abstract :
Steel plate shear walls are commonly used as structural lateral load resisting load systems in space-constrained areas. Many studies indicated that the implementation of the steel plate shear walls improves the ductility, stiffness and ultimate strength of the structure for which the interconnection of the steel infill plate with boundary members has a significant role. The typical connection of the infill shear plates to the boundary elements has a high-level fixity despite the general convenient construction procedures. In this study, the connection of the infill plates to the boundary elements are precisely investigated by establishing more than 21 computational models after verifying the modeling methodology. The structural performance of the partially connected plates with different commonly used connections types are evaluated and compared to the corresponding conventional fully connected infill plate systems. It is shown that column-only connected infill plate shear wall reduces the structural lateral load resisting capacity tangibly more than beam-only connected infill plates due to limited tension field action development. In addition, results indicated that systems with partial infill plate connection and connectivity ratio of 80% or more generally have similar structural performance compared to conventional systems with full connected infill plates.
