摘　　要：针对T型节点强度预测大多是通过试验进行,但试验测试存在周期长、成本高等问题,特别是对节点进行尺寸优化后再次进行试验效率较低,有必要针对复合材料T型节点直接计算模型进行研究,实现对T型节点强度的快速校核。因此以复合材料T型节点作为研究对象,参考相关规范确定节点直接计算模型的边界条件、尺寸以及强度校核标准,得到一个用于T型节点强度校核的直接计算模型。The strength prediction of T-shaped nodes is mostly carried out through tests,but there are problems such as long cycle and high cost in test tests.In particular,it is low efficiency to conduct tests again after optimizing the size of nodes.Therefore,it is necessary to study the direct calculation model of T-shaped composite nodes to realize the rapid checking of the strength of T-shaped nodes.Therefore,taking T-shaped composite nodes as the research object,the boundary conditions,dimensions and strength checking standards of the direct calculation model of the nodes were determined by referring to relevant specifications,and a direct calculation model for strength checking of T-shaped nodes was obtained.
