Large-scale damage from earthquakes in ordinary buildings has been observed in different countries, dwellings built without any technical advice were devastated and even modern buildings based on seismic design suffered damages. This study analyses different types of structural response and assesses the destructive capacity of earthquakes. The assessment of the destructive capacity or degree of severity of earthquakes is determined by dynamic parameters of seismic records. Many of those dynamic parameters governing the structural response are sophisticated. Hence, it is vital to identify the properest earthquake intensity index to represent the structural response of buildings with a good correlation with the building seismic performance. Many methods can be found in the literature to assessment of damage potential of earthquakes. Some measures of the destructive capacity of earthquakes, such as the modified Mercalli intensity, are of a subjective nature and are strongly influenced by the quality, type and density of the construction. Analytical ones, such as that proposed by Arias (1970), consider only the characteristics of the seismic record. Other measures take into account some structure property, such as the maximum acceleration of the structure. Traditionally, one of the most used parameter in seismic analysis is the peak ground acceleration (PGA). This is due to the fact that PGA measurement is simple and easy, and is the best suited for short period structures. This facilitated the use of PGA as a popular intensity index. Nevertheless, with the technological advance, the height of buildings increased significantly, forcing to deeper research studies, involving energy dissipation systems based on inelastic deformations (Zahrah y Hall, 1984; Bertero y Uang, 1988). The objective of this research is to evaluate the most used intensity measurements, currently available in the literature, regarding their ability of seismic response prediction in ordinary buildings. The selected seismic records to evaluate the destructive capacity of earthquakes have various characteristics as there are the soil type, epicentral distance, duration, amplitude and frequency content, among others, suggesting this is a representative sample of the past worldwide Earthquakes. Results of the earthquake destructive potential assessment of the selected seismic records, are correlated with the global damage observed in buildings caused by the selected earthquakes, putting emphasis on the structural configuration able to reduce the damage.
