Seismic resilience is critical in the design of modern structural systems, particularly for steel moment‐resisting frames (MRFs). Traditional energy dissipation mechanisms, such as viscous or friction dampers, are effective but often involve high installation and maintenance costs. This study investigates the performance of pressurized sand dampers (PSDs) as an innovative and cost‐effective passive control device for mitigating seismic vibrations in steel MRF structures. The proposed system leverages the frictional and dissipative behavior of PSDs. This study presents a numerical analysis using a representative 3‐story steel MRF building. The PSD is integrated at selected locations within the frame. Time‐history analyses are performed using different earthquake input motions. The study focused on key structural response parameters, including the inter‐story drift ratio, the base shear, and the peak floor acceleration comparing the performance of the MRF with and without PSDs. The use of pressurized sand dampers reduces these seismic demands. This research provides insight into the practical implementation of PSDs for seismic control in multi‐story steel MRFs, offering a sustainable and adaptable solution for enhancing earthquake resistance.

Nonlinear velocity dampers (NVDs) embedded in coupling beams may enhance the seismic performance of frame–core tube structures by dissipating energy and limiting structural damage. This study evaluates the seismic performance of a 20-story reinforced concrete (RC) frame–core tube building incorporating NVD-equipped cou...

The present paper reports the results of the preliminary study geared towards investigating the effects of base‐connection design on residual drifts and prospective repairability assessment of seismically designed steel moment‐resisting frames (MRFs). To assess these implications, a single 4‐story steel MRF with four d...

Steel moment-resisting frames are widely used in seismic regions, but conventional beam–column connections often suffer from concentrated damage and difficult post-earthquake repair. To address these issues, this study proposes a novel replaceable energy-dissipating slit beam–column joint for steel frames. To enhance s...
To improve the seismic performance and post-earthquake recoverability of low- and mid-rise steel frames, this study investigates the seismic performance and layout strategy of a self-centering friction damper (SCFD) through experimental and numerical studies. The SCFD combines the superelastic restoring capability of s...

The seismic design of multi‐story steel buildings requires balancing structural efficiency, drift control, and material economy. This study presents a parametric comparison of moment‐resisting steel and steel‐concrete composite buildings, where steel beams interact with concrete slabs through shear connectors. Numerica...
