A damaged driveway bridge over Dudley Creek has been blocked off with warning tape. The sides of the bridge have slumped, and the driveway surface has buckled and cracked. In the background, the gates to the property are misaligned. The photographer comments, "The bridge to a large mansion on a huge section was displaced by half a metre".

A simple and rapid approach to post-earthquake assessment of bridge condit…
Research papers, The University of Auckland Library
The paper proposes a simple method for quick post-earthquake assessment of damage and condition of a stock of bridges in a transportation network using seismic data recorded by a strong motion array. The first part of the paper is concerned with using existing free field strong motion recorders to predict peak ground acceleration (PGA) at an arbitrary bridge site. Two methods are developed using artificial neural networks (a single network and a committee of neural networks) considering influential parameters, such as seismic magnitude, hypocentral depth and epicentral distance. The efficiency of the proposed method is explored using actual strong motion records from the devastating 2010 Darfield and 2011 Christchurch earthquakes in New Zealand. In the second part, two simple ideas are outlined how to infer the likely damage to a bridge using either the predicted PGA and seismic design spectrum, or a broader set of seismic metrics, structural parameters and damage indices.
