Developments in the unified performance-based seismic design

Developments in the unified performance-based seismic design This review article provides an overview of the origin, development and applications of unified performance-based design (UPBD) method of seismic design of structures. The method is an up gradation of direct displacement-based design (DDBD). In DDBD, drift is the only design criterion. In UPBD method, both drift as well as performance level are accommodated in the design philosophy. Apart from satisfying two design criteria, the UPBD method also provides member size at the start of the design, which eliminates iterations for getting adequate member sizes. Since its inception in 2008, the method has been applied to various structures. A comprehensive review of this method is reported here. The application of the method in dual system, reinforced concrete (RC) frame buildings, bridge piers and steel frame buildings have been discussed in details. The determination of column size, effect of effective stiffness, equipment performance etc. in the domain of UPBD method have also been highlighted. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Building Pathology and Rehabilitation Springer Journals

Abstract

This review article provides an overview of the origin, development and applications of unified performance-based design (UPBD) method of seismic design of structures. The method is an up gradation of direct displacement-based design (DDBD). In DDBD, drift is the only design criterion. In UPBD method, both drift as well as performance level are accommodated in the design philosophy. Apart from satisfying two design criteria, the UPBD method also provides member size at the start of the design, which eliminates iterations for getting adequate member sizes. Since its inception in 2008, the method has been applied to various structures. A comprehensive review of this method is reported here. The application of the method in dual system, reinforced concrete (RC) frame buildings, bridge piers and steel frame buildings have been discussed in details. The determination of column size, effect of effective stiffness, equipment performance etc. in the domain of UPBD method have also been highlighted.
