Abstract
The increasing traffic on both railways and roads increases the risk of accidental collision
with bridges and buildings. One way to prevent disproportionate collapse of structures if an
unforeseen accident occurs is to make the structure robust. A structure that is robust has the
ability to withstand progressive collapse initiated by local failures. The aim of this Master
thesis is to study the term Robustness and the focus will be on robustness of bridges. The aim
is also to investigate if a bridge, designed according to the Swedish building code, is robust.
The knowledge and understanding of robustness is limited in Sweden. That is partly due to
the lack of defined design criteria in today’s building code. In order to increase the... (More)
The increasing traffic on both railways and roads increases the risk of accidental collision
with bridges and buildings. One way to prevent disproportionate collapse of structures if an

is also to investigate if a bridge, designed according to the Swedish building code, is robust.
The knowledge and understanding of robustness is limited in Sweden. That is partly due to
the lack of defined design criteria in today’s building code. In order to increase the structural
safety and to create a better understanding about robustness, there should be guidelines in the
building code on how to design the bridges supports and on how to protect the supports from
collisions. The studied bridge has been analyzed with the finite element program
BRIGADE/Plus. The simulation is based on a collision where one of the supports is damaged
and taken out. The simulation shows that the bridge would be able to survive the accident
when only deadweight is considered. (Less)
