A STUDY ON EVALUATION FORMULA FOR MAXIMUM RESPONSE DEFORMATION ANGLE OF WOODEN BUILDING IN THE 2016 CENTRAL TOTTORI EARTHQUAKE

Abstract

 We propose a method to directly evaluate the maximum response deformation angle of wooden building without estimating earthquake ground motion at the point where seismic observation is not set. First, the evaluation formula of the maximum response deformation angle was derived based on the relationship between the equivalent performance acceleration response spectrum and the acceleration response spectrum. Subsequently, the valuation formula consists of the closest distance of the fault and the natural frequency of the microtremor H/V was obtained by regression analysis using the earthquake motion records obtained in the 2016 central Tottori earthquake. As a result, the maximum response deformation angle can be calculated from the earthquake observation record corresponded well with the value calculated from the proposed formula.
