Earthquake Saftey Assessment of a Tall Brick Chimney in Tokoname Based on the Micro-Tremor Measurement
Abstract eng: This paper deals with earthquake safety of the brick chimney of the height of 23 m in Tokoname, Japan. We measured micro-tremor to acquire vibration characteristics, which was used to construct FE model for the superstructure by simulating base-fixed horizontal natural frequencies. Soil-foundation interaction was treated by installing soil springs which were determined by simulating soil-coupled frequency. With the soil-coupled FE model, linear dynamic response analysis was carried out for four kinds of input ground motions. It is found that the base of the chimney will have damage at maximum acceleration from 41 to 77 Gal, should the collapse be caused by excessive tensile stress at mortal joints.
