| Abstrakt: |
This article presents the results of elastic analyses performed on three types of bridges, monolithic, continuous, and simple-supported, making changes to the regularity of the substructure. Such variations consist of increasing and reducing the height of the center pier, to determine conditions of vulnerability due to irregularity. The structures were subject to a database of 53 accelerograms recorded on the Mexican Pacific Coast. The maximum responses in displacement and standardized differences between the regular and irregular systems are presented. These data can be applied in preliminary evaluation methodologies and then in maintenance programs. |
