Seismic Damage Detection of Moment Resisting Frame Structures Using Time-Frequency Features
Shock and Vibration, 2018 To detect seismic damage of moment resisting frame (MRF) structures, a data-driven method using the fractal dimension (FD) of time-frequency feature (TFF) of structural seismic dynamic responses at measured stories is extended and refined.

Investigation of the Seismic Behavior of Framed Tube Buildings Considering Soil Structure Interaction [PDF]
Journal of Structural and Construction Engineering, 2019 In recent years, the framed tube system has been known as the most efficient structural system for the high-rise buildings. The entire lateral resistance in the framed tube structures is provided by closely spaced exterior columns and deep spandrel beams.
