河南艺术中心艺术墙为“单层索网次结构-钢管相贯桁架主体钢结构”体系。转换节点是实现主次结构共同工作力学效应、保证整体结构安全的关键节点之一。主次结构的连接转换节点有着与普通钢节点完全不同的索-钢接触单元的特殊构造,受力复杂。设计应用ANSYS软件对索钢转换节点进行带接触单元的弹塑性有限元计算分析,并进行足尺节点试验研究,确认了该复杂节点力学性能计算设计的正确性,确保了该类关键节点的安全性。
The art wall of Henan Art Center is “single layer cable network structure - the main steel structure of steel pipe intersecting truss ” system. Transforming nodes is one of the key nodes to realize the common mechanical effect of primary and secondary structures and ensure the overall structural safety. The primary and secondary structure of the connection conversion node has a completely different from ordinary steel node cable - steel contact unit special structure, the force complex. The application of ANSYS software is designed to analyze the elasto-plastic finite element of the contact element with cable and the full-scale joint test is carried out to verify the correctness of the calculation and design of the mechanical properties of the complex node and to ensure the safety of such critical nodes Sex.
