摘　　要：实际工程中,空腹混凝土网架节点的受力性能直接影响整个结构的受力性能,单独对节点进行受力分析已越来越被重视。过去节点大多为试验研究,由于试验成本和加载设备的限制,使得试验数据不可能覆盖工程节点实际尺寸的全部范围。近年来,随着有限元方法和迭代技术的发展以及计算机的普及,数值模拟方法已取代了试验方法成为主要的节点研究方法。要使混凝土网架节点的数值模拟分析结果准确可靠,必须建立一种准确有效的有限元模型。结合规范和工程实际情况,采用Solid 65实体单元模拟钢筋混凝土,对空间节点进行有限元静力分析。Concrete open--web grid structure nodes directly affect the mechanical properties of the structure of the force performance in ordinary project, stress analysis separately node has more and more attention. Experimental study on the last node mostly due to the cost of test and loading equipment limitations, making engineering test data can not cover the full range of the actual size of the node. In recent years, with the finite element method and the iterative development of technology and the popularization of computers, numerical simulation method has been replaced by a node test methods become a major research methods. To make concrete grid node simulation results were accurate and reliable, we must establish an accurate and effective finite element model. Specifications and engineering combined with the actual situation, the use of Solid 65 solid element simulation of reinforced concrete, the spatial node finite element static analysis.
