Reconstruction of Partially Collapsed Post-tensioned Beğendik Bridge During Balanced Cantilever Construction
Beğendik Bridge with a main span of 210 m has partially collapsed during construction in December 2017. The main reason for the partial collapse was a result of unfortunate events following each other. The collapse was simply triggered by removing a simple piece of timber support element from the scaffolding to have some space to place the unexpectedly oversize pot bearings on the abutment. No one has been injured or died during the collapse mainly due to ductile design of superstructure that allowed seven workers to escape from inside of the box girder within forty-five minutes. The focus of this paper on the description of the trigger mechanism of the partial collapse of the bridge, demolishment of damaged parts and reconstruction of the bridge. Following the collapse, a series of engineering scenarios have been evaluated to restart the construction. Reconstruction of the bridge has been started just in four months of time and bridge is still under construction.
