| 爆炸荷载作用下顶底角钢螺栓连接的性能研究 |

| 摘 要： | 爆炸或冲击荷载可致结构局部损坏,有时会影响整个结构的安全,结构设计时必须考虑这种情况。连接是增强钢结构延性和鲁棒性的重要手段,可减轻这种破坏。采用有限元方法研究爆炸荷载作用下顶底角钢螺栓连接的性能。采用ANSYS有限元软件,对有、无腹板角钢的顶底角钢螺栓连接进行分析。通过比较模型数值结果和试验数据,对有限元模型进行验证。对连接模型施加简化爆炸荷载,分析了爆炸荷载作用下连接的性能,确定连接临界面。对爆破荷载作用下连接的破坏模型和实用性进行简单讨论。

The Behavior of Top and Seat Bolted Angle Connections Under Blast Loading |
| |
| Abstract: | Abnormal loading generated by blast or impact may cause local damage in a building that may evolve to affect the whole structural system.Therefore,structures have to be designed to prevent such disproportional consequences.Connection is an important contributor to ductility and robustness of the structural steel systems in mitigating such consequences.Considering this importance,finite element analysis is used in this paper to study the behavior of top and seat bolted angle connections under blast loading. ... |
