Many
historical stone arch bridges have been exposed to the different environmental
effects, which could cause structural damage, at different times. Under these
natural or human-induced effects such as floods, earthquakes, the bridges were
partially or completely damaged. The repair of the historical arch bridges has
been repaired against to these damages. The success of the repair work depends
on both a detailed archaeological-historical survey and a detailed structural
evaluation process carried out together. It is very important to determine the
answers to questions such as date and time of construction of the structure,
whether there was any interruption in the construction process, the scheme and
the order of the damages of the structure, what were the repairs and
strengthening done in the structure and whether there was any change in the use
of the environment. After these process, the repair method is determined
considering many alternatives such as partial or complete disassembly for
remodeling of the bridge, regional repair or regional strengthening, full
strengthening of the upper structure, removal of excess weight over the bridge,
balancing of mass and stiffness distribution, improvement of structural
interaction between arches and feet, strengthening of foundation system of the
bridge. In this study, the repair methods against the damages occurred on the
historical masonry arch bridges exposed to different damages have been tried to
be evaluated.
