Human Induced Excitation - Abstract:
- The goal of this thesis is to add to the body of literature on predicting vibrational behavior in multistory buildings. To achieve this goal, the following research question is proposed: Can a multistory ETABS model predict the possibility of whole building vibration issues due to human induced excitation? The focus of this thesis was developing a modeling procedure that is capable of producing a model that can capture the multi-story response that was seen in a case study building. The ten-story case study building had a combination of dance studio spaces and office spaces on various floors. Vibrations caused by people dancing on one floor resulted in occupants on another floor in an office space complaining about annoying vibrations. This thesis starts by going over the current literature available for evaluation building vibrations and modeling approaches to use for predicting human induced vibrations. From there, a model was created and evaluated to see the dynamic response of the structure. It was found that it is possible to get a multi-story vibrational response out of a model in ETABS from human induced loading that represents the in-situ behavior. In the end, the amplitude of the floor accelerations obtained from the model did closely match the in-situ values. From the results obtained through the model created and the sensitivity analysis performed in this thesis, valuable insight was gained as to how certain assumptions effect the modal properties of an ETABS model when analyzing floor vibrations.
