摘要通过试验和数值模拟，研究了弦杆轴压对承受支撑面外弯曲的双T形管节点极限承载力的影响。给出了具有不同水平弦压缩的四个实验测试的结果，以及使用非线性有限元程序进行的参数研究的结果。将计算结果与美国石油学会的DT节点设计规则进行了比较。
Abstract The effects of chord axial compression on the ultimate strength of a double-tee (DT) tubular joint subjected to brace out-of-plane bending have been studied both experimentally and numerically. The results from four experimental tests with different levels of chord compression are presented, together with the results of a parametric study using non-linear finite element procedures. The results are compared with the American Petroleum Institute's design rules for DT joints subjected to combined brace and chord loading.
