摘要

摘要: 细长直管道系统，相比于纵向其横向的力学性能对管道的稳定性更重要；对直管道支架抗震性能进行研究，考虑连接方式对管架抗震性能的影响，管道支架与底部基础采用螺栓连接和焊接，设计了SJ1和SJ2两试件进行拟静力试验，并建立管道支架的有限元模型。在获得准确有限元模型的条件下对管道支架构件进行考虑不同中面板构造形式、肋板数量以及连接方式等支架细部构造的参数分析，最终获得具有良好抗震性能的管道支架构造参数。研究结果表明：该文采用螺栓连接的支架构件由于螺栓易被拉起未能充分发挥支架结构的抗震性能，相较于螺栓连接，管架与底部基础采用焊接连接时支架构件试验及有限元分析所得滞回曲线相对饱满，骨架曲线较高，耗能能力较强，表现出相对较好的抗震性能；不同中面板构造形式的支架结构其骨架曲线、耗能能力曲线数值差异不大，刚度退化规律基本一致；增加竖向肋板的数量，支架构件抗屈曲能力增强，承载力和耗能能力得到显著提高，当竖向肋板数量为2个时，有利于协调管道支架的承载力、强度、刚度和耗能能力，更好发挥支架结构的抗震性能。

Abstract: Compared with the longitudinal mechanical properties, the transverse mechanical properties of the slender straight pipeline system are particularly important for the stability of the pipeline. The transverse seismic performance of slender straight pipe support was studied. Considering the influence of connection mode on the seismic performance of the pipe support, and the pipe support and the bottom foundation were bolted and welded, two specimens, i.e., SJ1 and SJ2, were designed for quasi-static tests, and the finite element model of the pipe support was established. On the basis of the finite element model, the detailed structural parameters of the pipe support considering the connection mode, the structural form of the middle panel and the number of ribs are analyzed, and finally the structural parameters of the pipe support with good seismic performance are obtained. The results show that the bolted bracket members fail to give full contribution to the seismic performance of the bracket structure because the bolts are easily pulled up. Compared with the bolt connection, the hysteresis curve of the welded pipe frame and the bottom foundation is relatively plump, with higher skeleton curve and stronger energy dissipation capacity, indicating a relatively good seismic performance. The skeleton curves and energy dissipation capacity curves of the bracket structures with different middle panel structure forms have little difference, with similar stiffness degradation law. A larger number of vertical ribs leads to enhanced buckling resistance of pipe support members, with the bearing capacity and energy dissipation capacity being significantly improved. When the number of vertical ribs is 2, it leads to better bearing capacity, strength, stiffness, energy dissipation capacity, and better seismic performance of the supports.
