Perspectives in the estimation of seismic spectrum of bridges design in Colombia
Abstract
Considering the geographic location of Colombia and the advances in research reached by developed countries, it is necessary to update and modify the current standard earthquake- resistant design of bridges in Colombia. One of the design parameters that requires improving and updating is the design spectrum (seismic demand) considering the estudies of local seismic risk, already made in many of the most important cities of the country. In this paper, the preliminary results of an analytical investigation in the field of structural and seismic engineering are presented, where an evaluation and a comparisson of the methodologies proposed in Colombia as well as world-wide are made, to evaluate the seismic demand in bridges structures. Additionally, a case of study is shown, and the results obtained using the proposed design spectrums in the different analyzed methodologies are presented.Downloads
