STUDY ON WIND RESPONSE CHARACTERISTICS OF HOKEKYOJI FIVE-STORIED PAGODA

Wind response characteristics of the Hokekyoji five-storied pagoda is investigated by applying probabilistic statistical method to displacement data during strong wind obtained from image measurements. And rainflow method is used to estimate restoring force characteristics from the displacement data at the five-storied pagoda. Using the estimated restoring force characteristics, an earthquake response analysis is performed with the ground acceleration of the Tohoku Pacific Coast Earthquake as input, and the validity of the estimated restoring force characteristics is verified. Furthermore, wind response analysis is performed using the restoring force characteristics and wind force time series obtained from wind tunnel test results.
