【Abstract】 The paper researches on the dynamical characteristis of an eccentric chemical workshop with the help of software ANSYS; then it compares different dynamical responses caused by earthquakes from different orients. In order to reduce the torsional coupled effect, the paper brings forward that the knightheads setting along the transverse direction can improve the aseismic property economically and effectively.更多还原
