摘要
高层建筑消防管道系统在地震作用下承受复杂动力荷载,支架结构的稳定性直接影响给水系统功能的可靠性。从布置特征与节点响应入手,分析抗震支架与管道耦合行为,构建基于承载力控制的布置优化模型,明确间距、方向与锚固方式对系统刚度的控制路径。结合天津项目实测数据,验证布置策略的适应性,结果显示振动响应下降,应力集中特征明显缓解,支架系统稳定性提升。模型可以应用于高层建筑复杂给水系统抗震设计,为提升建筑防灾性能提供数据基础与优化路径。
The fire protection pipeline system of high-rise buildings bears complex dynamic loads during earthquakes action,and the stability of support structure directly affects the functional reliability of the water supply system.Starting from the layout characteristics and node response,this study analyzes coupling behavior between seismic supports and pipelines,constructs a layout optimization model based on bearing capacity control.It clarifies the control path of spacing,direction,and anchoring methods influence system stiffness.Based on the actual test data of the Tianjin project,the adaptability of the layout strategy was verified.Results show a decrease in vibration response,a significant alleviation of stress concentration characteristics,and an improvement in the stability of the support system.The model can be applied to the seismic design of complex water supply systems in high-rise buildings,providing a data foundation and optimization path for improving building disaster prevention performance.
