Abstract

In this Chapter are presented the results of the numerical evaluation of the seismic response of an eight-levels RC framed building who suffered light damage by the 2009 Tucacas Earthquake (6.4 Mw). The building was designed according the current Venezuelan codes, splitting the structure in three different modules in order to avoid the negative effects of in plan irregularities and represents a typical mid-rise building located on high seismic-prone areas. Each module was modelled and analyzed independently using non-linear standard techniques (pushover analysis and incremental dynamic analysis). The seismic action was defined by a set of synthetic design-spectrum compatible accelerograms. In order to improve the original seismic design of the building, a new building was proposed using an innovative energy-based procedure. The set of dynamic analyses was used in order to formulate a new procedure for the determination of fragility curves. Results show that the new procedure is suitable in order to predict the damage state which the building may reach when it is subjected to a strong earthquake. This seismic event leads to evaluate the current design and construction practices in order to ensure the life of the population and to reduce the seismic vulnerability of less developed countries.
