摘　　要：文章研究了一款十字形新型连接节点在地震荷载作用下对整体试件结构力学性能的影响。基于施工中常见的钩头螺栓节点,设计一种具有较高承载力和耐久性的新型柔性节点,通过拟静力试验与有限元数值模拟相结合的方式分析十字形新型连接节点的力学性能,从而验证其可靠性。试验结果表明:十字形新型连接节点具有良好的抗震性能及耗能能力,提高了结构在地震荷载作用下的承载力和耐久性,相比于钩头螺栓节点,具有更好的实用性和推广性。The effect of a new cross-shaped joint on the mechanical properties of the whole specimen under seismic load were studied.A new flexible joint with high bearing capacity and durability was designed based on the common hook head bolt joint in construction.The mechanical properties of the new joint were analyzed through the combination of pseudo-static test and finite element numerical simulation,so as to verify its reliability.The results showed that the new cross-shaped joint had good seismic performance and energy dissipation capacity,which improved the bearing capacity and durability of the structure under seismic load,and were more practical and replicable than the hook-head bolt joint.
