Abstract

This paper shows the behavior of composite steel structures filled up with concrete under unit impulse. Combining Finite Strip Method and Finite Element Method, we can analyze dynamic response of composite shell structures having arbitrary shapes. Impulsive stress propagates as group waves. The group waves influenced by the direction and position of the unit impulse can be explained clearly by strain energy generated in the structures. The characteristics of wave propagation and group wave are discussed by using strain energy.
