The Usage of Anti-tension Material and Its Advantages

From the past to the present, various solutions have been produced against the earthquake force, which significantly affects the structures. One of these solutions is the use of seismic isolation system. One of the purposes of using seismic isolators is to minimise the acceleration caused by the earthquake force that will affect the structure and the damage that will occur. Seismic isolators work in both vertical and horizontal directions while performing their functions in accordance with this purpose. The vertical load capacity of isolators varies depending on the type of isolator and the diameter of the isolator. One of the criteria used in the selection of isolators in the design of base isolation structures is the axial load value to which the isolator system will be subjected. Particularly in the base isolation solutions of thin and long structures, some isolators may be subjected to tensile forces due to the tip-ping movement that the structure is likely to experience during an earthquake. In this case, although increasing the diameter of the isolator is a solution, this solution is not preferred because it increases the overall cost, negatively affects the architecture of the structure and increases the difficulty of the test phase for this situation. The aim of this study is to mention how the anti-tension device, which can be used as another solution to the extra tensile force, can bring a solution to this situation and to provide information on its application by revealing the advantages of this material. To this end, the ETABS programme has realised a design in the form of an excessive tensile force in isolators and has demonstrated the benefits of using this material.
