Generally preferred RC frame systems, due to their construction methods, are insufficient to
meet the rapidly increasing housing demand economically without compromising safety. Tunnel Formwork
Systems (TFSs) have started to be used frequently as a reason for their fast manufacturing, economical
solution, and earthquake reliability. Since TFSs have a considerable lateral stiffness, they can be preferred
especially in buildings to be built in high seismicity regions. For this reason, the design of TFSs and the
understanding of their earthquake behavior become extremely important. It is assumed that the "Non-Linear
Time History Analysis" (NLTHA), which is a dynamic analysis method, gives closer results to the real
behavior. According to the “Turkish Seismic Code for Buildings (TSCB) 2018”, earthquake records should
be scaled to the design earthquake and TSCB 2018 suggests two scaling methods as "Simple Scaling (SS)"
and "Spectrum Matching (SM)". In this study, the effects of considering different scaling methods defined
in TSCB on the seismic behavior of TFSs have been investigated. For this purpose, an analytical model of
a six-story TFS building has been prepared in SAP2000 with a “nonlinear shell-layered element” and
NLTHA has been performed. Scaling methods have been compared in terms of the top displacements and
base-shears of the building. According to the results of this study, the SS method generally gives more
conservative estimations than the ones obtained for SM. However, looking at the mean values, it can be
said that this difference is insignificant in terms of overall behavior.
