MALDONADO RONDON, Esperanza; GOMEZ ARAUJO, Iván Dario  and  CHIO CHO, Gustavo. Simulating vulnerability functions and seismic damage probability matrix for reinforced concrete frame buildings. Ing. Investig. [online]. 2008, vol.28, n.3, pp.28-40. ISSN 0120-5609.

This paper outlines vulnerability functions and seismic damage probability matrixes being constructed for reinforced concrete frame buildings. These functions and matrixes were based on simulation techniques and experts’ opinion. The proposed functions and matrixes relate a building’s vulnerability to the level of damage which might be incurred, depending on an earthquake’s motion. Vulnerability was defined by estimating an index proposed by expert opinion. Damage was defined by means of a damage index depending on nonlinear static analysis. Simulation techniques were used for constructing hypothetical buildings and thereby to building the functions and matrixes. Such buildings represented the typical characteristics of Colombian cities’ reinforced concrete frame system ( Bucaramanga for example). A set of tools was made for constructing and applying these functions and matrixes, allowing us to determine the level of seismic damage by using the buildings’ characteristics for specific seismic action.

Keywords : seismic vulnerability function; seismic damage probability matrix; seismic vulnerability; seismic damage; concrete building, frame.
