AB  - This study presents a Performance-Based Plastic Design (PBPD) 
  methodology for the design of steel Concentric Braced Frames (CBF). The design 
  base shear is obtained based on energy-work balance using pre-selected target 
  drift and yield mechanism. The 3 low-to-medium rise CBF 3, 6 and 9-story were 
  designed by the proposed methodology and current seismic codes. Results of inelastic 
  dynamic analyses showed that the PBPD frames met all the intended performance 
  objectives in terms of yield mechanisms and target drift levels but the code 
  compliant frames showed very poor response due to premature brace fractures 
  leading to unacceptably large drifts and instability.
