Supporting data for: Accurate estimation of the long-period transition period in the two-period design response spectrum based on Turkish ground motion records and its application to a three-tower cable-stayed bridge

This repository contains the supporting data for the study entitled “Accurate estimation of the long-period transition period in the two-period design response spectrum based on Turkish ground motion records and its application to a three-tower cable-stayed bridge.” The dataset was prepared to support the reproducibility and transparency of the analyses presented in the manuscript.The uploaded data mainly include the selected ground motions matched to two different design response spectra, as well as the comparative results of component responses of a three-tower cable-stayed bridge under spectrum-compatible ground motions and actual ground motions.The dataset is intended to document the ground-motion selection and comparison procedure adopted in the study and to provide the numerical basis for evaluating the differences in structural responses under different seismic input scenarios. It supports the figures, tables, and conclusions reported in the paper.
