Abstract:
|
Bridges are constructed in a way that they ensure safe traffic and that they resist all actions durably. In order to ensure the traffic safety bridges are fitted with safety barriers. The safety barriers usually installed on German bridges are designed to protect lorries up to a weight of 13 t from breaking through the barrier and crashing down the bridge. But in case of accidents with heavier vehicles conventional safety barriers reach the limit of their capabilities. Therefore a research project was initiated in order to obtain safety barriers which are able to protect even heavy lorries from breaking through and crashing down, without simultaneously concerning about unacceptable bridge damages. Within the research project real crash tests of vehicles towards safety barriers were executed - for the first time inclusive measuring all important forces acting on bridges.
