| 摘要： | Rigorous numerical analyses are conducted to study the effects of bidirectional lateral cyclic loading on the hysteretic response of stocky circular thin-walled steel columns. Four unidirectional and eight bidirectional lateral displacement controlled load paths are considered; different performance indices obtained from the lateral load paths under consideration are compared. The results obtained from these comprehensive numerical analyses indicate that bidirectional lateral cyclic loading has a very limited effect on the ultimate strength of stocky circular thin-walled steel columns, but significantly decreases the ductility when compared with unidirectional lateral loading. |
