“…Such ground motion is produced by directivity, ing action, basin edge effects, and fracture bumps. They impose higher seismic demands on the structure and can also in uence the dynamic behavior of the structure (Poreddy et al, 2022). The results of this study suggest that more attention should be paid to vulnerable high-risk points to manage unsafe districts, and the demands should move towards safer structures and infrastructures in assigned areas.…”

The vulnerability analysis of structure and infrastructure damages is an essential step to estimate the possible effects of an earthquake to decrease the loss of key system factors. This study was conducted aiming to shine light on seismic analysis and performance evaluation of lifeline networks during earthquake sequences with insight into resilience. Probability Seismic Hazard Analysis (PSHA) was used to analyze seismic hazard; and EZ-Frisk application was used to analyze seismic hazard, spectral matching modeling, and site response. ZMAP software was used to detect and locate future earthquakes, considering local seismic tectonic conditions. To detect the resilience level of the lifeline networks, key point localization and geospatial mapping were performed using GIS software. Maximum displacement in this study was estimated to be approximately 68 cm. The distribution of these values resembles the acceleration of the earthquake. In the part concerning seismic studies, the location of future earthquakes for the next event was also proposed for two other areas. The highest level of sensitivity and vulnerability was located in the center and toward the northeastern part of the study area. The results of this study suggested that a particular attention should be paid to vulnerable high-risk points and the demands should move towards safe structures and infrastructures in assigned areas.

“…In structural damage assessment, commonly used peak values alone do not lead to an understanding of the damage potential of strong ground motions to structures. Many other ground motion parameters can contribute to structural damage [30]. The seismic parameters given in Table 1 are classified according to acceleration, velocity, displacement, frequency and ground motion duration.…”

Energy-based seismic analysis and structural design require understanding the seismic input energy response of reinforced concrete buildings subjected to strong ground motions. Thus, calculating and predicting input energies becomes of great importance. The object of this study is to introduce a regression model for predicting the seismic input energies of reinforced concrete buildings using the 6 February 2023 Kahramanmaraş earthquake. For this purpose, three regular 3, 6 and 9-storey residential reinforced concrete buildings are designed. Input energy response histories of buildings subjected to a set of horizontal acceleration histories of 67 stations of the February 6 Kahramanmaraş earthquake were obtained. Subsequently, the ground motion parameters were used to estimate the input energies. It was revealed that acceleration-based parameters generally had better consequences than velocity-based parameters in low periods, while the opposite was the case in high periods. This study proposed new equations in which multiple ground motion parameters are combined to better reflect input energy from a single parameter. As the height and period of the buildings increase, the multiple linear regression coefficient decreases and the estimation of input energy becomes difficult with the ground motion parameters.
