  • Abstract:
  • In modern years, the term Performance Based Design is being used as a popular buzzword in the field of earthquake engineering, with the structural engineer taking keen interest in its concepts due to its potential benefits in assessment, design and better understanding of structural behavior during strong ground motions. The basic idea of Performance Based Design is to conceive structures that perform desirably during various loading scenarios. Furthermore, this notion permits the owners and designers to select personalized performance goals for the design of different structures. However, there is a need to emphasis that some minimum level or minimum acceptable criteria are required to be fulfilled by all structures. In the context of seismic design, it has been realized that the increase in strength may not enhance safety, nor reduce damage. The distribution of strength through the building rather than the absolute value of design base shear is now considered of importance, as endorsed by the capacity design principles. At the same time, the objective of most codes is to provide life safety performance during large and infrequent earthquakes. However, recent earthquakes have shown that structures may suffer irreparable or too costly to repair damages. Besides, inelastic behavior, indicating damage, is observed even during smaller earthquakes. It seems that Performance Based Design concepts, which consent multi-level design objectives, could provide a framework to improve the current codes; by obtaining structures that perform appropriately for all earthquakes. Current research developments in seismic structural behavior indicate that the most suitable approach of achieving the performance objectives is by performing a damage-controlled design. The most important is to perform an evaluation process easy to be applied but that gets the main features that considerably influence the performance objective. Various recommendations are made in order to implement this ideology into the design procedure.
