摘要
针对某古塔结构的主要受力和变形特点,并遵循"保护第一"和"修旧如旧"的古建筑保护原则,设计了3种SMA阻尼器,提出了将其安装于古塔结构以提高其抗震性能的保护方案,探讨了SMA阻尼器的安装方式及确定其数量的计算方法,并进行了装有SMA阻尼器的古塔模型结构振动台试验。试验结果表明,文中所提SMA阻尼器可有效地提高该古塔结构的抗震能力,且对其他历史建筑的保护和修复也具有一定的参考意义。
In the light of the ancient building protecting principle "protect first" and "repair like the old",3 kinds of shape memory alloy(SMA) dampers were designed;a protection scheme for ancient pagoda structure to improve the earthquake resistance of the pagoda was proposed;shaking table tests were performed on the model structure of pagoda in two cases: installed with and without SMA dampers unerected.Test results demonstrate that the SMA dampers can fulfill the valid seismic energy dissipation,effectively strengthen the anti-seismic capacity of mosque pagoda structures and are worthy to be further exploited and extensively applied.
