Failure of horizontal support system to adjacent buildings during reconstruction in Eskisehir

Approximately, 65% of the existing residential structures are adjacent in Turkey. In addition to the social disadvantages of living in adjacent buildings, these structures are prone to pounding during earthquakes and they are under threat during the construction and demolition of the neighboring structures. The neighboring structures may experience damage during/after the demolition of adjacent structures due to pounding of structural components. There are many cases of casualties and economic losses due to the collapse of neighboring structures during the demolition of old structures. The damage can be occurred as a result of constructing shared foundations, different foundation depths, the groundwater level, and possible impact of the work machine during demolition. Also, in areas with high seismic risk, there is a possibility of an earthquake at a time between the demolition and reconstruction stages of a building, which can cause significant damage. Due to these reasons, the design and construction stages of adjacent structures should be described by building codes in detail. In order to renew the adjacent structures at different times, horizontal support elements should be used and required design calculations should be made. This study examines the truss system applications as horizontal support in such structures built in Eskisehir. The characteristics of the section and system properties, the horizontal load carrying capacity, the choice of support zones between the adjacent structures, and the characteristics of strain deformation are determined. It is concluded that the horizontal support applications prevent horizontal forces due to earthquakes and various vibrations in neighboring structures and prevent structural deformation.
