河南艺术中心40m高悬臂玻璃艺术墙,采用“单层索网次结构-平面钢管相贯桁架主体结构”体系。对幕墙索网次结构与主体钢结构的共同工作、主次结构转换的“索-钢接触”连接约束条件对主体钢结构及索网次结构的影响进行研究。考虑索网次结构与主体钢结构共同工作,对主体结构稳定安全性有利,但对幕墙索网次结构安全性有较大的不利影响。根据研究结果要求幕墙设计单位对索网次结构进行加强设计,确保了工程整体结构的安全。 Henan Art Center 40m high cantilevered glass art wall, using “single layer cable network structure - the main structure of flat steel pipe intersecting truss ” system. The main work of the curtain wall cable network structure and the common work, the primary and secondary structural transformation of the “cable - steel contact ” connection constraints on the main steel structure and cable network substructure. Considering that the cable sub-structure cooperates with the main steel structure, it is beneficial to the stability and safety of the main structure, but it has a greater negative impact on the safety of the sub-structure of the curtain wall cable. According to the research results, curtain wall design units are required to strengthen the design of the cable network substructure to ensure the safety of the overall structure of the project.
