STRESS DISTRIBUTION IN BRIDGE FRAMES

Stress distribution in bridge frames is measured in a series of tests on damaged end posts with angles turned out, solid cover plate on top and lacing on the bottom and on two other end posts with angles turned in, solid cover plate on top and perforated cover plate on the bottom. Each end post is loaded to failure at each increment of increase in damage, with damage varying from none at the first test to severely damaged condition for the final tests on an end post. It is concluded that the model bridge with damaged end posts has greater capacity than was expected by bridge engineers. Both types of end posts fail at the same load for straight, undamaged condition, although the latticed type suffers localized failure whereas the perforated cover plate type suffers integral-type failure.
