Özet:

In the energy-based seismic design approach, the earthquake ground movement is considered as an energy entrance to structures. The energy that enters the system during the earthquake is equal to the total of the kinetic energy formed in the structure system, decomposition energy, elastic shape change energy and hysteretic energy components. Therefore, it is important to know the amount of energy that enters the system and how it is consumed. This study assessed the behavior of the default and unique freedom-degree (TSD) structural systems designed according to the TBDY (2018) standards in the center of Elazığ province, scaled according to the DBYYHY (2007) and TBDY (2018) design spectrum. For this purpose, three different earthquake drive records were selected. These drive records, taking into account the area where the structures are located, have been used by separate extension according to the design spectrum created for the four floor classes of both regulations. A two-right model for the nonlinear behavior of the building elements has been considered. The TSD models' movement equations are solved in the time definition field using the Newmark average drive method. After the location changes of each structure model are determined, the classical work-energy formula is applied to the movement equation, the energy entering the system is obtained by the earthquake effect. Changes in space, cutting forces and energy input for structural systems have been assessed.
