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 矩形钢管混凝土t 、 y型节点是一种新型的节点形式,在我国现行的规范规程中对于这类节点都还没有涉及。
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 采用壳单元、实体单元和接触单元建立了节点的有限元模型,有限元分析综合考虑了材料非线性、几何非线性和接触非线性问题。
