  7. Abstract:
  8. The AISC Seismic Design Provisions now include capacity design requirements for steel plate shear walls,which consist of thin web plates that infill frames of steel beams, denoted horizontal boundary elements)HBEs), and columns, denoted vertical boundary elements (VBEs). The thin unstiffened web plates are expected to buckle in shear at low load levels and develop tension field action, providing ductility and energy dissipation through tension yielding of the web plate. HBEs are designed for stiffness and strength requirements and are expected to anchor the tension field formation in the web plates. VBEs are designed for yielding of web plates and plastic hinge formation at the ends of the HBEs.FEMA P695 describes a recommended methodology for reliably quantifying building system performance and response parameters for use in seismic design. The recommended methodology) provides a rational basis for establishing global seismic performance factors (SPFs), including the response modification coefficient( R factor), the system overstrength factor (Ω0), and deflection amplification factor (Cd), of new seismic-force-resisting systems proposed for inclusion in model building codes.The purpose of this Methodology is to provide a rational basis for determining building seismic performance factors that, when properly implemented in the seismic design process, will result in equivalent safety against collapse in an earthquake, comparable to the inherent safety againstcollapse intended by current seismic codes, for buildings with different seismic-force-resisting systems
