REVIEW OF THE RESEARCH ON STEEL STORAGE RACK STRUCTURES

  • 摘要: 随着物流和电商行业的飞速发展,钢货架结构从单纯提供货物存储功能的简单机械类产品逐步向高位立体库、库架合一式建筑发展,这对货架结构的安全性提出更高要求。与传统钢框架结构相比,钢货架结构的托盘货载远大于结构自重,竖向荷载活恒比值可达10∶1量级;主要竖向承重构件多采用连续开孔薄壁截面,其性能受到局部屈曲、畸变屈曲、整体屈曲以及各屈曲模式间相互作用的影响;梁柱节点和柱脚节点多为半刚性挂齿式机械连接,表现出强非线性和捏拢滑移滞回特征;竖向支撑体系对整体结构稳定性的影响机制和有效性。另外,在地震作用下,货架结构的破坏模式除了主要承重构件的破坏和整体结构的垮塌外,还存在托盘货载跌落导致的货物、结构破坏和人员伤害。在钢货架结构抗震分析中,托盘货物的滑动和跌落应属于一种极限状态加以考虑,托盘与横梁间的动力摩擦系数将成为评估结构性能的一个重要参数。结合国内外已有研究成果,该文基于钢货架结构的特点,评述了现有的研究方法,综述了各基本结构要素的力学行为、整体结构的稳定性态及抗震性能,探讨了研究中的关键问题。

摘要: 随着物流和电商行业的飞速发展,钢货架结构从单纯提供货物存储功能的简单机械类产品逐步向高位立体库、库架合一式建筑发展,这对货架结构的安全性提出更高要求。与传统钢框架结构相比,钢货架结构的托盘货载远大于结构自重,竖向荷载活恒比值可达10∶1量级;主要竖向承重构件多采用连续开孔薄壁截面,其性能受到局部屈曲、畸变屈曲、整体屈曲以及各屈曲模式间相互作用的影响;梁柱节点和柱脚节点多为半刚性挂齿式机械连接,表现出强非线性和捏拢滑移滞回特征;竖向支撑体系对整体结构稳定性的影响机制和有效性。另外,在地震作用下,货架结构的破坏模式除了主要承重构件的破坏和整体结构的垮塌外,还存在托盘货载跌落导致的货物、结构破坏和人员伤害。在钢货架结构抗震分析中,托盘货物的滑动和跌落应属于一种极限状态加以考虑,托盘与横梁间的动力摩擦系数将成为评估结构性能的一个重要参数。结合国内外已有研究成果,该文基于钢货架结构的特点,评述了现有的研究方法,综述了各基本结构要素的力学行为、整体结构的稳定性态及抗震性能,探讨了研究中的关键问题。
