MODELLING AND ANALYSIS OF HUMAN STRUCTURE INTERACTION

Abstract

Vibrations induced by human are increasingly important serviceability and safety issue in the field of dynamics. Lately, there have been an expanding number of issues identified with human induced vibrations of bridges, floors, staircase, etc. The interaction between human and structure is vital, however, is a new thought while designing slimmer structures possessed and dynamically excited by human. So this interaction is complex, interdisciplinary and it is not analyzed very often. It can be known how human can impact the dynamic properties of designing structures and auxiliary vibrations can influence forces produced by human inhabitants. In this thesis the acceleration response in vertical direction for a pedestrian bridge (simply supported beam) is anticipated by taking a single pedestrian who walks with various pacing frequencies. Then response curves for accelerations are generated and the variation of acceleration with pacing frequency is analysed. The acceleration values are also compared with the given standards.
