【Abstract】 The model of a steel silo is built and simplified by using the method of Rotter’s effective length and the finite element analysis program LS-DYNA,and the collapse behavior and the deformation mode of the transition junction is analyzed and calculated.The computational results are compared with the predictions of Rotter’s simulation of small-deflection theory and large-deflection theory.更多还原
