Estimation of natural period is indispensable for evaluating dynamic behavior such as wind induced vibration and earthquakes. However, it is complicated to estimation of natural period of truss tower supported steel chimney. Because there are many members that making up truss tower, it is impossible to uniquely determine the weight and stiffness of truss tower, and also chimney body weight concentrating on the tower support point height depends on the number of parts to support and the height. This paper presents estimation formula of natural period truss tower supported steel chimney except such kind of complicate process.
