Abstract
The bridge damage due to the past earthquake hugely affect the transportation systems. Many such bridges were designed with outdated regulation codes. The strong motion in several elements show how vulnerable such structures are. Generally, conventional bridges are low-cost construction but it requires high maintenance cost hence integral bridges reduced life-cycle cost and long-term maintenance. The integral bridge gives improved design efficiency and improved riding quality more than the conventional type of bridges. This study analytically determines the seismic fragility of an Integral box girder bridge. A set of 10 excitation records of ground motion considering near field area is utilized for nonlinear dynamic analysis of the bridge. A 3-D finite component model theme is employed during this study considering nonlinearity within the bridge piers. The part fragility curves area unit combined to judge the fragility curves for the complete bridge system at completely different injury states. The unstable demand consists in a set of nearfield ground motions to judge the probability of exceeding the unstable capability of the mentioned bridges.
