The concrete - filled rectangular hollow sections ( cfrhs ) t - and y - connections are the novel kind of welded - truss connections , which have not yet been concerned by the existing codes or specifications in china 矩形鋼管混凝土t 、 y型節點是一種新型的節點形式,在我國現行的規范規程中對于這類節點都還沒有涉及。
The behavior of concrete - filled t - and y - connections is examined by means of nonlinear finite element analysis ( fea ) . the connection is modeled using shell , solid and contact elements , and analyzed concerning material , geometric and contact non - linear 采用殼單元、實體單元和接觸單元建立了節點的有限元模型,有限元分析綜合考慮了材料非線性、幾何非線性和接觸非線性問題。
