Abstract: Knowing the behavior of building structures through the interpretation of the results of different tests is indisputably the most correct approach to mathematics, mechanics and engineering. Among other things, should be given proper attention differentiation of the analysis, that our approach to each of them will manage to get the necessary and appropriate results in relation to the time spent for each of them. In the material that follows, I’m focused to address the concept of Vulnerability, for defining it as a practical factor in assessing the structure risk, mainly from seismic actions. Serving this concept I have exploited nonlinear analysis (PUSHOVER) and within the segment in which appeared that the structure posses resistance,I have realized two models of vulnerability. Mechanic model that provides physical state of the structur for different levels of seismic force and Economic model which develops the mechanical model by using economic parameters in terms of reinforcement. The concept of mechanical model aims to liberate the local performance of the structure by modeling its global performance. The concept of these models is addressed in the following paragraphs, together with reflections and improvements about this model. This vulnerability model has an advantage as it is very simple to be realized furthermore is more applicable for the purpose of strengthening the existing structures, as conducts an accurate correlation between the performance of the structure, risk, the level of restoration and total cost.
