초록
In this paper, allowable acceleration for horizontal vibration in buildings was estimated by shaking table. Human comfort of occupants is satisfied by using the peak acceleration in NBCC and ISO6897 used by Korean structural engineer. We used one-dimensional shaking table for horizontal vibration tests, and a vibration house made similar to a living space was made. Experimental results were recorded by increasing acceleration in the range of 0.2Hz through 1.2Hz of frequency after organized into five experimental groups, each of which was composed of eight persons. We obtained performance curves by dividing the distribution of perception from horizontal vibration tests into the range of 0～25%, 26～50%, 51～75%, 76～100% and then fitting curves. Also we made questionnaire based on human comfort criteria of foreign countries, and examined the feeling of subjects. From the results of horizontal vibration tests, it was found that acceleration of perception was low when frequency was high, and that visual and auditory senses affects the human perception for horizontal vibration.
Abstract
In this paper, allowable acceleration for horizontal vibration in buildings was estimated by shaking table. Human comfort of occupants is satisfied by using the peak acceleration in NBCC and ISO6897 used by Korean structural engineer. We used one-dimensional shaking table for horizontal vibration tests, and a vibration house made similar to a living space was made. Experimental results were recorded by increasing acceleration in the range of 0.2Hz through 1.2Hz of frequency after organized into five experimental groups, each of which was composed of eight persons. We obtained performance curves by dividing the distribution of perception from horizontal vibration tests into the range of 0～25%, 26～50%, 51～75%, 76～100% and then fitting curves. Also we made questionnaire based on human comfort criteria of foreign countries, and examined the feeling of subjects. From the results of horizontal vibration tests, it was found that acceleration of perception was low when frequency was high, and that visual and auditory senses affects the human perception for horizontal vibration.
