Acceptibility Curves Derived from Motion Simulator Investigations and Previous Experience with Building Motion

Abstract eng:
A vital part of the design of tall buildings is the prediction of wind-induced motion and the assessment of its effects on occupant comfort and well being. Investigations reported herein aim to shed light on the formulation of acceptability criteria using results from three motion simulator studies and from a preliminary investigation focusing on the analysis of information pertaining to individuals with previous experience with wind-induced building motion. From the motion simulator studies it was shown that subjects’ semantic evaluation of motion is dependent upon the input waveform, with a near sinusoid producing the least incidence of nausea and task disruption. The duration of the stimulus was shown to be an important factor in the consideration of a motion’s acceptability, and frequency dependence of the semantically evaluated task disruption factor was demonstrated. The importance of furthering the acquisition of data from individuals with previous experience with tall building motion in wind storms, for the purpose of developing a relationship between the severity and effects of motion on an individual’s well being, was highlighted.
