Human-Structure Dynamic Interaction

It is well known that people who are standing or sitting on a vibrating structure have capacity to increase the damping of the system significantly, which leads to the decrease of the vibration response compared with the response of an unoccupied structure. However, the way how people who are walking over a structure (such as a footbridge), or jumping or bouncing on a structure (such as a grandstand) influence structural behaviour is still not well understood. The aim of this project is to enhance understanding of the influence that human activities have on dynamic properties of the human-structure system through combined experimental and analytical approach.

    Dynamic Properties of Human Body

    Dynamics of the human body has potential to strongly influence the dynamic behaviour of the slender structures used and dynamically excited by humans. While the dynamic properties of passive (standing or sitting) people are relatively well researched, the dynamics of the human body in action (i.e. preforming various activities such as walking or jumping) is still under-researched area. The aim of this project is to study human body dynamics through experimental quantification of kinematics of the human actions in the Gait Laboratory and biomechanical modlling of people's bahaviour.

      Time domain dynamic force models are traditionally used for modelling pedestrian traffic. Although they provide detailed insight into vibration performance of a structure, their usage for modelling complex multi-person traffic scenarios could be time consuming and limited by the computing facilities available. For this reason, modelling pedestrian traffic in the frequency domain could offer great advantages over time domain models. This project aims at developing frequency domain force models for distinct traffic scenarios and their verification using data acquired on as-built structures.

        Synchronisation of Human Activities on Assembly Structures

        Apart from serving as sport venues stadia structures are increasingly used for hosting music and other entertainment events. In both scenarios, these structures are exposed to activities, such as jumping, bouncing and swaying, by crowd of spectators, who can be more or less well synchronised. This project aims at investigating the level of synchronisation between people performing different activities. Experimental part of the project could partly or fully be conducted in the Gait Lab, situated in the School, equipped with modern motion capture facility.

            Vibration Serviceability Design of Staircases

            Slender staircases are a frequent architectural feature, especially in public spaces. Although significant progress has been made in recent years in designing vibration serviceable floors, similar guidance for staircases is currently limited, resulting in low confidence in the design and often lively and unfit for purpose structures.

            This project aims to deveop guidance for designing vibration serviceable staircases exposed to human-induced dynamic loading. This will be achieved through a combined experimental and numerical study having the following objectives: (1) to develop a reliable force model for ascending/descending stairs, (2) to verify the model on as-built stair structures available for this study, and (3) to suggest tentative vibration tolerance limits.

            To quantify the dynamic force induced while ascending and descending stairs a continuous force will be measured using a motion capture system VICON, available in the Gait Lab in the School of Engineering. The data collected could be used to develop a mathemitical model for the dynamic force, taking care of inter- and intra-subject variability in the force induced. The model will then be varifiedon a number of as-built stairacases exposed to single and multi-person traffic. In addition, inteviews of stair users about their perception of vibration on lively stairs will be conducted to establish vibration perception and tolerance limits for the structures investigated.
