Seismic Performance Evaluation of a Prestressed I-Type Girder Bridge in Daegu for ICT Based Disaster Management in Daegu Metropolitan City
Abstract One of the most typical bridges in the Province of Daegu (Korea) is prestressed I-type girder bridges. Due to the lack of seismic detailing, this bridge may be vulnerable to earthquake events. In an effort to prevent an interruption of the transportation network, which could be catastrophic for Daegu, a comprehensive research program was conducted whose aims were to assess the seismic vulnerability of typical bridge classes. The understanding of the impact of various modeling parameters on structural-component responses is the first step in a forward-vulnerability assessment of bridges in Daegu. This paper presents part of a comparative study using detailed finite element nonlinear models that was conducted to assess the longitudinal and transverse responses of multi-span continuous prestressed I-type girder bridges in their as-built configurations using code-based loading of Korea. Deterministic responses in terms of column curvature demand, abutment footing deformations are provided for the longitudinal and transverse directions of bridge models.
