vehicle traffic has increased on the roads. By definition, the route of such vehicles
should be planned in detail, adapted to the road gauge and agreed with the relevant
authorities and institutions. Often, however, the carelessness and bravado of drivers
and carriers can lead to a threat to traffic safety as well as the safety of the engineering
facilities themselves, which are on the route of an oversized vehicle. The situation in
which the object is damaged by a car impact is one of many that during the operation
of the object may cause a sudden redistribution of internal forces.
Bridge failures arouse quite wide offers, but there are no compact and comprehensive publishing positions about this list. On a global scale, there are several extensive
items describing bridge failures such as D.W analysis. Smith from 1977 [1] concerns
143 bridge disasters and a newer item from 2010 [2]. These deficiencies are available
from some confidentiality investigation documents regarding the actual causes of the
merger or disaster, and will be subject to their consequences, requesting transactions
and financial advice. They are often “blanked” and it is difficult to obtain reliable
information about them. However, it is worth reviewing references to the last two
Conferences in Construction Failures to get to the conclusion that this problem is not
at all marginal [3–6]. In the list of cases, these are only descriptions of the situation
together with a description of the extent of connections and corrective actions [4].
Less often, analysis of span analysis attempts with reports confirmed by information
[3, 6].
However, several descriptions of in-depth analysis appeared in the world literature,
including modeling of the phenomenon of collision with a detailed model of a striking
vehicle and a non-linear model of the bay [7, 8]. This simulation makes it possible
to assess the degree of danger in the event of a vehicle colliding with a bridge
span, predicting the effects of such an event, and seeking and designing appropriate
safeguards.
This article deals with the problem of redistribution of internal forces that occurred
as a result of damage to the bridge structure girders caused by the impact of an
oversized vehicle. Using the Sofistik computer program, a three-span viaduct in a
five-girder and seven-girder variant was modeled. The structure of damage to the
bottom of the structure as a result of vehicle impact in the middle of the span of the
second span was determined in the object. Static and strength analyzes of the viaduct
structure were carried out, comparing the results obtained for the original condition
and the damaged condition.
2 Redistribution of Internal Forces in the Exploitation
Stage
During their operation, bridge structures are exposed to various phenomena that may
affect the redistribution of internal forces. Along with the increase in communication
in recent years, oversize and oversized vehicle traffic has increased on the roads. By
