| Abstract: | The performance of space lattice structures can be significantly affected by the cumulated damage of material caused by large deformation and obvious material plasticity under severe earthquakes.The spatial experiment of circular steel tubes under cyclic axial and horizontal loads was conducted to get a rational constitutive model.The hysteretic behavior of specimens with different slenderness ratios and different loading schemes was investigated.Then,finite element models were developed using a user-define... |
