Structural Retrofitting of Existing Stone Siphon by Internally Concrete Lining

Abstract

Nowadays, the devastating effects of natural disasters and methods of protection from these effects are very popular. In the field of civil engineering, the issue of protecting structures against natural disasters has always been on the agenda. For this reason, research on the protection of all building types against natural disasters is of vital importance. It seems that stone siphons, especially those used for irrigation purposes, are negatively affected by earthquakes. As a result of this situation, problems are encountered in accessing water and flowing water. Post-disaster modal performance levels of stone siphons should be examined and as a result, appropriate retrofitting techniques should be applied according to the structure type, damage and regional conditions. Various retrofitting methods are available to increase the seismic performance and stiffness of stone siphons. The retrofitting method with concrete lining also stands out as an alternative, simple and popular. For all these reasons, this study focused on retrofitting stone siphon with concrete lining. A stone siphon model was created with the finite element method and modal analysis was performed. Then, the same model was retrofitted with concrete lining and modal analysis was performed. When the results obtained were compared, it was seen that retrofitting with concrete lining significantly increased the stone siphon rigidity. In light of all these findings, it is recommended to retrofit concrete lining for stone siphons.
