About us

The Dynamics Lab, set up by Dr Mateusz Bocian thanks to the support from the Polish National Agency for Academic Exchange (NAWA), commenced operation in September 2020. We are based in the Department of Roads, Bridges, Railways and Airports within the Faculty of Civil Engineering at Wrocław University of Science and Technology (Politechnika Wrocławska), Poland.


Our mission

We tackle urgent and evolving engineering problems and conduct fundamental research of which results have potential applications to real word challenges. We like to push boundaries in anything we do and often find ourselves questioning the status quo. We are driven by curiosity and the desire to make an impact. We find inspiration in diverse ways, but it often starts from seemingly simple questions beginning with: why, how, and what if. It is common that the answers to these questions open up a wide range of opportunities we end up pursuing for the advancement of science and society.

Our research

At the centre of our research are humans and the built environment, and their multifaceted interaction. Our research interests are encapsulated by the following themes:

  • structural dynamics, in particular vibration serviceability;
  • structural health monitoring;
  • sensors and signal processing;
  • stability and control of human gait and posture;
  • integration of sensory information during the execution of motor tasks;
  • crowd dynamics;
  • virtual and mixed reality.

Calibration of the inverted pendulum pedestrian model for laterally-oscillating structures based on stepping behaviour
2023-11-10

A biomechanically-inspired inverted pendulum pedestrian model (IPM) was first introduced to the field of structural engineering by John H.G. Macdonald in 2009 [1]. The original IPM has been shown to qualitativelly capture pedestrian behaviour on laterally-oscillating structres, including the structural excitation mechanism. However, to make it suitable for use in engineering applications, it had to be reconciled with empirical observations. This task has been accomplished in our recent paper.

Resonance curve - the case of pedestrian laoding on structures
2022-12-06

Resonance is one of fundamental concepts in structural dynamics. In simple terms, it occurs if a periodic force is applied to the (structural) system at or near one of its natural frequencies. This leads to the amplification of the response relative to the case when no resonance occurs. The consequences of this phenomenon can be severe, from accelerated degradation of the structure, lack of fitness for its purpose, to the catastrophic failure. Therefore, understanding this phenomenon is of critical importance to any engineer.

Dynamic performance verification of the Rędziński Bridge using portable camera-based vibration monitoring systems
2022-12-06

Monitoring evolving patterns of the dynamic behaviour of long-span bridges is a critical task in their maintenance and management. For the bridges lacking permanent monitoring systems, ad hoc testing campaigns are sometimes implemented. These are typically costly and utilise wired instrumentation systems requiring a direct contact with the structure, hence they can create risks to the involved personnel and equipment. An alternative solution is explored in our newest paper, reporting successful attempts at obtaining modal damping based on data from optical motion capture systems.

A methodological approach towards evaluating structural damage severity using 1D CNNs
2021-10-26

Monitoring civil infrastructure simplifies and improves reliability of decision-making in asset management. This task is increasingly important in established economies, in which engineering infrastructure has aged thus becoming exposed to various risks affecting structural integrity. In the latest paper, driven by our friends at the University of Leeds, we have explored the performance of 1D CNN in structural damage detection based on numerical simulations.

Performance of camera-based vibration monitoring systems in input-output modal identification using shaker excitation
2021-10-14

A complete dynamic characterisation of structures requires modal frequency, mode shape, modal damping and modal mass to be established for each mode. This can be achieved by using experimental modal analisis (EMA). EMA requires an input force and the resulting structural response to be measured. Optical vibration monitoring systems, enabling remote sensing, could make this process less challenging. This very issue was explored in our latest paper.

Performance of optical structural vibration monitoring systems in experimental modal analysis
2021-02-15

A considerable research effort has been spent in recent years on the development of machine vision techniques for structural vibration monitoring. However, experimental modal analysis relying on the measurement of input force and the resulting structural response towards the full dynamic characterisation of structures has not been previously investigated in this context. In our recent paper we have explored the performance of optical vibration monitoring systems in experimental modal analysis in which the excitation force comes from an instrumented hammer.
