SIMPLE METHOD FOR EVALUATING CUMULATIVE TIME OF WIND SPEED FOR ESTIMATING FATIGUE DAMAGE

Abstract

Increasing number of high-rise buildings are being equipped with energy absorption devices of elasto-plastic materials. It is important to ensure the safety of these devices to not only under design wind speed but also under cumulative fatigue damage due to wind loading during use. In determining cumulative damage, it is necessary to evaluate the cumulative time of wind speed in a period and the wind response to each wind speed. This paper presents a simple method for evaluating the cumulative time of wind speed in a period and its effectiveness.
