Special Issue Information

Dear Colleagues, 

Earthquake resilience is a critical concern in the design and construction of modern infrastructure. The development of innovative materials and structural systems that can withstand seismic forces is essential to ensure the safety and longevity of buildings and other structures. Advanced materials, such as high-performance concrete, fiber-reinforced polymers, and shape memory alloys, along with novel structural designs, play a pivotal role in enhancing earthquake resistance. Techniques for seismic retrofitting, base isolation, and energy dissipation are also crucial in mitigating the impact of earthquakes on existing structures.

In this Special Issue, we invite submissions that delve into the latest research and advancements in earthquake structures and materials. We welcome both theoretical and experimental studies, as well as comprehensive reviews and survey papers. Topics of interest include, but are not limited to, innovative materials for seismic applications, advanced structural systems, seismic performance assessment, retrofitting techniques, and case studies of earthquake-resistant design and construction.

On 22 May 2012, a magnitude Mw 5.6 earthquake struck the Pernik region of western Bulgaria, causing structural damage in nearby cities, including Sofia. This study assesses the seismic response of a six-story reinforced concrete building in central Sofia, utilizing real accelerogram data recorded at the basement (SGL1) and sixth floor (SGL2) levels during the earthquake. Using the Kanai–Yoshizawa (KY) model, the study estimates inter-story motion and assesses amplification effects across the structure. Analysis of peak ground acceleration (PGA), velocity (PGV), displacement (PGD), and spectral ratios reveals significant dynamic amplification of peak ground acceleration and displacement on the sixth floor, indicating flexible and dynamic behavior, as well as potential resonance effects. The analysis combines three spectral techniques—Horizontal-to-Vertical Spectral Ratio (H/V), Floor Spectral Ratio (FSR), and the Random Decrement Method (RDM)—to determine the building’s dynamic characteristics, including natural frequency and damping ratio. The results indicate a dominant vibration frequency of approximately 2.2 Hz and damping ratios ranging from 3.6% to 6.5%, which is consistent with the typical damping ratios of mid-rise concrete buildings. The findings underscore the significance of soil–structure interaction (SSI), particularly in sedimentary basins like the Sofia Graben, where localized geological effects influence seismic amplification. By integrating accelerometric data with advanced spectral techniques, this research can enhance ongoing site-specific monitoring and seismic design practices, contributing to the refinement of earthquake engineering methodologies for mitigating seismic risk in earthquake-prone urban areas.
