Abstract
In this paper, the relationships between static load-carrying capacity and seismic resistant capacity are focused on, that is, the comparison study is carried out about elasto plastic behavior of both responses. The purposes is to establish an evaluation method of allowable maximum earthquake acceleration, which may bring a structure into an ultimate state. The both elasto plastic behavior is analyzed for single layer lattice domes under vertical loading, which is a static vertical uniform load and a vertical seismic motion. The relationships between equivalent velocity of static absorbed energy and vertical deformations are focused on as a static elasto plastic behavior. The other relationships is the maximum earthquake input acceleration and the equivalent velocity of strain energy of domes as a dynamic elasto plastic behavior. Consequently, the change of slopes between the elastic and plastic ranges may be concerned with each other.
