Jianzhu Gangjiegou Jinzhan, 2011 铝合金结构在国内外应用十分广泛,具有诸多优点,我国目前已经建成了10多处大型的铝合金空间结构。本文总结了国内外在铝合金结构常温下以及高温下的材料特性和受压构件的研究现状。目前,发达国家对铝合金结构的研究相对成熟,对高温下铝合金受压构件的研究日趋完备。国内针对铝合金结构的研究也越来越深入和广泛,对各类构件都有研究,其中对轴心受压构件的研究最为深入,但还没有进行高温下的铝合金受压构件承载力的研究。因此有必要进行高温下铝合金受压承载力的研究,并给出可以用于工程设计的计算公式。

Jianzhu Gangjiegou Jinzhan, 2019 提出了一种具有环向预应力的三重钢管防屈曲支撑(three-tube buckling-restrained brace,TTBRB)。该防屈曲支撑由位于中间层提供轴向刚度和承载力并耗散地震能量的芯材钢管,以及分别位于芯材外部和内部限制芯材整体屈曲和局部屈曲的外套管和内套管等3部分组成。内、外套管与芯材钢管之间设置高分子聚乙烯材料制作的减摩层,以减小芯材轴向变形过程中内、外套管与芯材之间的摩擦力。相比用实心截面芯材的传统防屈曲支撑,用空心圆管作为芯材具有更大的回转半径;且取消了混凝土类填充材料 ...
