Performance Based Design is creating structures for predictable performance for assumed initial loads. This method is used to create a unique building or to consider an existing system. In performance-based design, structural forensic engineering takes place to originally determine the precise performance of the structures in having the talk with the owner and then move with the design or evaluation of the existing structure. Performance-based design is highly used in association with seismic loads. Yet, in modern design, performance-based design is issued in wind designs, earthquake designs, blast analyses and design and advanced collapse studies. Evaluation of the current structure or designing structure against potential earthquake load completed initially is accomplished. In contrast to the traditional design approach, PBD needs engineers and architects to assess project performance objectives earlier in the design stage to comprehend and control the characteristics affecting th
