PERFORMACE-BASED PLASTIC DESIG (PBPD) METHOD FOR EARTHQUAKE-RESISTAT STRUCTURES
This paper presents a brief overview of Performance-Based Plastic Design (PBPD) method as applied to seismic design. The method uses pre-selected target drift and yield mechanism as key performance limit states. The design base shear for selected hazard level(s) is calculated by equating the work needed to push the structure monotonically up to the target drift to that required by an equivalent SDOF to achieve the same state. Plastic design is performed to detail the frame members and connections in order to achieve the intended yield mechanism and behavior. The method has been successfully applied to a variety of common steel framing systems, and validated by inelastic static and dynamic analyses. In all cases, the frames developed desired strong column sway mechanisms, and the story drifts and ductility demands were well within the target values, thus meeting the desired performance objectives. Comparisons of responses with corresponding baseline frames designed by current practice have consistently shown the superiority of the proposed methodology. The work-energy equation can also be used in seismic evaluation of structures.
