Structural dynamics and vibration control involve the study and manipulation of the dynamic behavior of structures, such as buildings, bridges, and mechanical systems, in response to external forces or disturbances.

Research Areas

• Modal Analysis: Investigating the dynamic characteristics of structures, such as natural frequencies, mode shapes, and damping ratios, to understand their behavior under various loading conditions.
• Structural Health Monitoring: Utilizing sensor networks and data analysis techniques to continuously assess the structural integrity and detect damage or degradation in real-time.
• Nonlinear Dynamics: Investigating the behavior of structures under nonlinear loading conditions, including the study of chaos, bifurcations, and limit cycles, to understand and predict complex dynamic responses.
• Active Vibration Control: Investigating techniques and algorithms for actively controlling vibrations in mechanical systems using actuators and sensors. This may include methods such as adaptive control, robust control, and model predictive control.
• Passive Vibration Control: Exploring materials and structural designs to passively dampen vibrations without requiring active control systems. This may involve the use of damping materials, tuned mass dampers, or vibration isolators.
• Semi-Active Vibration Control: Researching control strategies that combine elements of both active and passive vibration control techniques. Semi-active control systems adjust damping characteristics or stiffness properties based on real-time feedback without requiring as much energy as active systems.
• Seismic Analysis and Control: Assessing the dynamic response of structures to earthquakes and developing seismic control strategies to enhance resilience and mitigate damage.
• Optimal Design of Vibration Control Systems: Investigating methodologies for optimizing the design of vibration control systems to achieve desired performance objectives while minimizing cost, weight, or energy consumption.
• Multi-Objective Optimization: Studying approaches for simultaneously optimizing multiple conflicting objectives in vibration control systems, such as minimizing vibration levels while maximizing energy efficiency or structural robustness.
