影响索-混凝土组合梁节点受力性能的主要因素

索-混凝土结构能够充分发挥组合材料在技术和经济上的优越性，体现了现阶段工程材料的发展方向，是一种极具发展潜力和应用价值的组合结构。节点是结构中的关键部位，也是施工难点，合理地设计节点对结构的安全和整个工程的造价具有重要的理论意义与工程实际价值。采用ANSYS软件研究了混凝土强度、节点梁端箍筋配筋率、梁柱纵筋配筋率等因素对节点受力性能的影响规律，获得完整、准确的节点受力性能信息，对于正确进行框架分析，保证结构体系的安全可靠具有重要的意义。

Main Influence Factors of Mechanical Properties on the Nodal of Cable-Concrete Beam

Concrete filled steel tubular structure gives full play to its two materials＇ superiorityin technology and economics over others, embodies the development direction of the engineering material at present, it is a composite structure with great development potential and application value. The joint is the key part of the structure, it also has technology difficulties in construction. The reasonable design of the joint related to the safety of the structure and the cost of the whole project, it is of great significance in the theoretical research and the engineering application. There-fore, obtaining complete and accurate information about the joints＇ performance is of great important for the frame analysis and the safety and reliability of the structure.
