CARRILLO, JULIÁN. EVALUATION OF THE SEISMIC VULNERABILIY OF STRUCTURES USING A PERFORMANCE DESIGN. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.155, pp. 91-102. ISSN 0012-7353.

Due to the updating of the seismic design codes, the requirements and the seismic demand with which new structures should be designed, commonly are higher than those utilized during the design phase of existing buildings. The majority of the studies of vulnerability that should be carried out, are performed utilizing simplified methods included in the seismic design codes. Nevertheless, in most cases, they are too conservative and no quite representative of the real behavior of the structures. Using a performance design approach it is possible to have a better estimation of said behavior, permitting in most cases, to diminish or to eliminate the costs of a structural rehabilitation. In the article, the detailed description and a case of study of one of the available techniques for carrying out a study of seismic vulnerability utilizing a performance based design are presented.
